update: as colonel "hannibal" smith was wont to say on "the 'a' team," i love it when a plan comes together. well, maybe it was just shit house luck, but i prefer to think of luck as the residue of design.
to the 400 yard range this day, with an 8.5 inch target in tow. tape the target on the standard. back to the bench, a brick or two on the top, a blanket over that, and drape the rifle and myself over the blanket, pick five bullets from the box, and have at it.
sighting at the center of the bull, i let 'er rip. walk down to the target standard, and find that the target has emerged unscathed from the whole deal, and that there are five little holes about a foot or so below the point of aim in the cardboard backing.
back to the bench. five more shots, this time using the point of the bottom post of the plex reticule to aim. i have constructed a target by drawing the outline of a correl ware bowl (8.5" in diameter at the rim) on two sheets of typing paper, laying some scotch tape across it in a cross pattern, and then coloring in the little pie shaped figures around the clear tape in black marker pencil. that way, i have a white cross with a black contrast around it.
i simply edge the point of the plex post up the upright of the crossarm, until the black of the tip meets the black of the pie-shaped black shapes. and, fire off five more rounds. i walk down to the target again, and find five shots, two shots just off the left edge of the circle, defining a 5.17" group, and the three closest shots in a straight line up the lower right edge of the white cross, 2.20" inches apart.
pure shithouse luck, or skill? however it was done, the rifle shooting the 115 grain sierras at 2550 fps have shot a 1.29 minute of angle group at 400 yards, off the top of a blanket with no mechanical rest.
consider the center of the target the second button on a shirt or tunic. viewed that way, the shots to the left are just above the left nipple and right on the bottom rib below the nipple, with the other three shots just to the left of the mid sternum. in short, the group is satisfyingly accurate, and, in a needed situation, very much lethal at 400 yards.
in sum.--
a rifle with one load, and not changing scope settings or fooling around with "clicks" on the turret, shoots into a 1.00" plus group at 100 yards, with a point of aim of the tip of the top plex, rings the gong dead center at 300 yards by the use of the intersecting cross hairs, and hits a target to point of aim at 400 yards with a point of aim of the tip of the bottom plex.
all, without any fuss or bother with scope settings, or figuring "comes ups," "dial downs" or how many clicks equals 6 inchs at 400 yards. shit house luck? the residue of design? who cares? it works. john jay 02.09.2011 end update.
to the range this day, to test a couple of variations of my "whisper," and to decide upon a standard loading for the same.
i loaded some "whispers" *** , loading 130 grain sierra boat tail gamekings (a lead tip instead of a hollow-point) and 130 grain speer hot core spitzers in front of the same charge, that being 6.6 grains of imr "trail boss." this load develops about 950 fps in my ar-15 rifle, equipped w/ a 20" barrel.
to cut to the chase, the sierras shot reasonably well, delivering a 2.1" group at 100 yards, and the speers did not shoot well at all, delivering a couple groups at 3.5" and 5.5" at 100 yards. these latter groups more or less confirmed previous experience, and previous performance.
this is nothing against the speer bullet. i use the same hot core spitzer in full power loads in preference to the sierras, and they shot very well at around 2350 fps over the chronograph. i get this performance by using a load from the speer manual no. 13, consisting of 26 grains of h-322 with a large rifle primer and a 130 grain hot core bullet. in my rifle, i get no indication of excessive pressure from this load, and it is fully 1/2 grain below the listed maximum.
i shot five 5-shot groups with the "whispers."
after that, i shot a single 5-shot group with my standard load of the sierra 115 grain bthp matchking (an "open tip" bullet) at 100 yards, and this bullet at 2550 fps delivered a 1.440" group, with four shots within .775" of one another: the errant shot was the third, and was simply the result of an aiming error on my part when the sear dropped. i knew it was " ... bad when it left the barrel ...," as the saying goes, and that shot was entirely upon me, landing low and directly below the nice little cluster. the load consists of 28.2 grains of h-322 behind a 115 grain sierra bullet, the load from the hodgdon web site.
the rifle will shoot, when i do my part.
i want to talk to you about "systems," and devices, which i do not particularly like and which to my mind are to be avoided as useless and nettlesome complications. in short, i resist whenever possible the resort to very high powered scopes with lots of nobs and settings and twisting to be done at this range and that range, when shooting a firearm.
were something to go horribly wrong in this world, and i had to resort to my rifle to protect myself, i do not want to have to be sorting through this box or that box for my 276 yard ammo, and to set my scope to the 276 yard setting, when that it highly inconvenient.
k.i.s.s. keep it simple, stupid. i like that motto. its fits me. its regrettable, but i don't do "needless complication" very well.
for instance, this day i shot the groups at 100 yards with one bullet traveling 2550 fps and another traveling about 950, using the same target, the same scope, and the same scope settings.
and, another fellow and i used the rifle to shoot a steel gong at 300 yards, with the same rifle, the 115 grain sierra bullet at 2550 fps, without changing the scope settings at all, and by holding the rifle dead smack dab on the middle of the gong at that distance.
as a matter of fact, the rifle is "zeroed" to the 300 yard distance. it shot dead on at that distance. it also shot dead on using the high velocity load at 100 yards, without changing the scope setting at all. as for the whisper cartridge, it shot 7 inches below point of aim at 100 yards, also without changing scope settings: for reference, it is just about 7 inches from the point of my nose to the knit neck of my t-shirt.
how is this possible?
i have fixed on my rifle a leupold 2x7 power vari-x compact glass optic. "dead stock," right off the shelf. i have used it on .22 rifles, and on a rifle chambered in 7mm remington magnum.
when i shoot the long range gong with the high velocity ammo, i hold directly to point of aim using the cross hairs, the intersection fo the same right on the target. simple. just like me. at that range, i don't want to be using any guesswork, as there isn't a whole lot of room for error.
when i shoot the 100 yard target, i hold dead on the intended point of impact as well. how is that possible? well, in reality it is quite simple. the 2x7 leupold has a "plex reticule," which consists of four stadia which are wide at the outside of the field of view through the scope, and then narrow to points about 3/4's the way to the center of the scope. from there, the stadia are narrow as they lead toward and "meet" at the center of the scope. i simply use the top stadia as the "sight", and hold the sharp tip of the same directly on the intended point of impact.
rest assured, you can aim as precisely with the sharp tip of the stadia as you can with the cross hairs. and, it just so happens, that set at "7" power, the stadia tip is dead on at 100 yards with the above load, and close enough with anything else i will shoot through the rifle that i simply will not worry about it.
for instance, the aforementioned 130 grain speer full power load shoots to the same basic point of aim, and though there is some difference, it is less than i can compensate for by "kentucky windage," so i just hold dead on.
and, finally, i use the same method when aiming at short distances with the "whisper." except, instead of using the tip of the top stadia when shooting the low velocity round, when shooting targets i use the tip of the bottom stadia to aim the rifle. is this novel? nope, not really, the germans are quite fond of scoped rifles that basically use a bottom stadia all by its lonesome to effect aiming. and, when you think about it, the front sight of a rifle using "iron" sights aim with a blade at the front of the barrel which are nothing more than "posts" sticking up in the air all by their lonesome.
i do not use a range finding laser device to measure distance.
i do not have trajectory charts with "come ups" and "dial downs" taped to the stock of my rifle, nor do i have such information memorized. and, i do not have a little notebook with all such arcane information written in it, along with corrections for elevation and atmospheric pressure.
nor do i have such information stored on a laptop that i carry with me shooting.
i do have an old palm zire pda with art pejsa's ballistics program loaded on it, and it is helpful in noodling such things out, so that i can figure how to use my scopes to do the above little tricks.
why do i eschew the technology that would allow me to plant a bullet on the brow of a gnat at 312.69 yards, along with the 8x24 power scope that would allow me to see it?
hey, i am not that good a shot. what i mean by that, is that, i am not that good a shot. i do not shoot well enough to take advantage of that sort of thing. i don't need a ferrari testa rosa to drive 55 mph in the slow lane, either.
and, there is another reason. well, two. the second reason, is that for my purposes, i don't need to be that damned good a shot. minute of grapefruit is just fine for most purposes, and it has proved sufficient for most of the armies of the world for over a century of use of smokeless high velocity weapons.
(i am looking at frank barne's "cartridges of the world," 8th edition, 1997, edited by m.l. mcpherson. on page 447 -- 459, there is published an index to u.s. military ammunition, which sets forth, among other things, the accuracy stands for specific types of ammunition. at p. 449, we find the description of the m59 ball cartridge, caliber 7.62mm nato, loaded with the 150.5 grain bullet. under the heading "accuracy: carton or clip pack," we find the notation, "... 5 inch mean radius at 600 yards ... ," which i understand to mean that the bullet is capable of landing within a radius of 5" at a 600 yard target. actually, this is pretty impressive.
but, hold on a second. a radius is one half of a diameter. this means that the bullet is designed to land within a circle the diameter of 10 inches at 600 yards. that still isn't too bad, and in fact the bullet is designed to shoot into a 1.666 minute of angle cone at 100 yds. but, hold on another second. that is just the performance level of the bullet. it says nothing about the degradation of that sort of accuracy by being shot out of a rifled barrel not of that quality of accuracy. and, finally, you may breathe after you consider what happens when you add the fallibility of the shooter firing the cartridge in a rifle of less than perfect conditions under very horrible circumstances.
the fact is, unless someone is a very skilled marksman with adequate time to set up a good shot, not very many adversaries or attackers are going to be hit, on purpose, by a single & precisely aimed shot at much over 400 yards or so. so, i don't worry about it. and, i am not going to change a system calculated to give me a reasonable probability of a hit at 350 yards or so, without a lot of fuss and bother, for the chance at being a better shot at distances not calculated to engender a whole lot of danger to an adversary.
are people shot at extended ranges? you bet. happens all the time. sometimes as a result of a shot by an extremely skilled rifleman, but, more often, as a matter of what we call tenderly in the pac nor west, "shithouse luck." hey, you get killed stepping off curbs in front of pakistani cab drivers, too, ... , and there is no arguing with fate.
the first reason, and the paramount reason, is that in any situation in which you are seriously intent on shooting a weapon to protect yourself, you just don't have all that damn much time. if you have the weapon at hand, and you need to use it right now, you are not going to have time to take your laser range finder from its case, aim it, lase the target, and then transfer that information into your trajectory calculator, and then dial up the "clicks" on your scope, turn it to the desired magnification, and then take precise aim, and blow the gnat away with a precision shot to the brow. off of your concrete rest, using a lead sled fixture to absorb the recoil of your weapon.
nope, you are gonna flop down on the ground, first thing, so you don't get your fool ass blown away standing there picking your nose figuring out what to do. oh, yeah, even on the gravel, and even on the prickly pair, and even in your dior.
then you are gonna charge your weapon, and you are gonna aim, and you are gonna shoot until you get the bastard who is trying to get you, or until he gets you, or until you can figure out a way to get the fuck outta there.
in short, you want things idiot proof. you want them simple. you want it pre-arranged, so that you don't have to be dicking around "getting set up" while some asshole is using the precious time to fix your ass.
so, with my "system", it is hold dead on at 300 yards, hoist her up a little bit for 400 yards, or for close in, 150 yards plus or so, you use the tip of the top stadia and aim to intended point of impact.
it is a butt wipe simple operation, because i am a butt wipe simpleton.
and, i got news for you. i am not going to get a whole lot smarter put into a situation where somebody is seriously after my ass, or shooting at me, or dragging my child off into the bushes. am i going to have the presence of mind to get my laser out, dial in my clicks, consult my trajectory chart in such a circumstance? i don't know about you, but i don't think that i am gonna. i am gonna be in pretty good shape if i can remember how to insert the magazine into the magazine well, and take aim and shoot.
this brings up something almost totally extraneous to anything, but it is just the little thing that i like. did you you that the french, our beloved froggies, haven't as an historical matter been in the habit of putting safeties on their infantry rifles. the french believe that if you are not worried, the chamber is not charged with a cartridge. and, that if you are worried, the chamber is charged with a round, so that when the gun is mounted it is capable of being discharged without having to dink around with putting the safety into the "fire" position.
in this, i am in agreement with the froggies.
keep. it. simple. stupid.
that is my "system." partly through design, and partly through "trial and error," i have with my little ar-15 in 6.8mm remington spc, a method whereby i can shoot the high velocity round that i load for my rifle from about 0 to 450 yards or so, without a whole lot of messing around with things. and, why am i not worried about distances greater than that?
well, the fact is, at those ranges, i will not be able to hit anything with sufficient reliability and predictability to warrant messing with it, a whole lot. well, i will mess with it a little. i have a target i have prepared, and i am going to go to the range tomorrow, and shoot at it at 400 yards, and then at 500 yards. am i going to change the scope settings to make sure i can hit those targets at that range?
no. i am not even going to think about it. i have a fair notion that it will not involve much to hit at 400 yards. and, i have a firm conviction, based on my experience walking in the country side and hunting in the mountains, that i cannot estimate range sufficient accurately at ranges over 300 to 400 yards to even worry about it. if i don't hit something at that range, i will simply figure out how to do so, on the spot.
now, i shot at elk years ago and in another life time at a measured 395 yards, confirmed by topo map and gps readings. (hey, the elk was dead, we had the time and some people had the equipment, and elk are pretty famous for not shooting you whilst you are consulting your trajectory charts.) i saw him, i slid down a saddle on my back below the line of shrubbery, and i laid the rifle over a sapling bent parallel to the ground in the previous years snow, and i compensated for the fact that it was a downhill shot, and held the cross hairs on "hair," as the old saying goes. at the shot he was down in a heap to 175 grains of 7mm bullet, and i had my spike. i held the cross hairs on a line extending up from his front leg, and on his shoulder just above the bent "elbow." some 10 or 15 seconds after he went down, he struggled a bit to get up, and i hit him again, mercilessly & mercifully (hey, hunting is complicated to me, like the love of a woman), and killed him without further quiver. his companion ran away at the second shot.
i took that shot with confidence.
not because i had a whole lot of doodads. i did not. but, i had busted a lot of rocks in those canyons, and i knew my rifle had the reach without a whole lot of calculation being necessary to make the shot.
simple. just like me.
and, were i you, i would keep it simple, too. that's my opinion on things, and just like everyone else, i have a couple of 'em, ... , just like nipples.

*** the "whisper" concept was developed by j.d. jones of ssk industries, and is a proprietary system whose name is trademarked, and the intellectual property in the same is the exclusive property of j.d. jones.
you want to buy a "whisper," contact j.d. jones at ssk. simple as that.
my little experiment simply uses his example as inspiration to achieve a desired end, and i do not use or follow the principles he uses in his developments. i do not use special cases, or special guns, merely working to attain sub-sonic performance from a cartridge case normally producing high velocities, while maintaining a semblance of accuracy, sufficient to give some utility to the use of the cartridge in that guise.
there. that is explained. has mr. jones ever given me a hint of grief over my scribblings? no, and i doubt that he is even aware of them. i just respect his pioneering efforts, ... , sure as hell, no one else even dreamed of any of this stuff before him, to the best of my knowledge, ... , and have no problems with him trying to make a buck from his thinking and work.
