the load. "jj's brit" ™ cases fabricated from remington peters cases in .243 winchester, as detailed more than once in these pages; 120 grain nosler ballistic tip bullets, seated to 2.440" inches overall cartridge length; 29.5 grains of h-4198 powder; cci 200 primers, and that's about it.
i had shot an exceptional group w/ the 120 grain bullet, but wanted a bit more velocity from the load. and, previously, i had fired a group with 29.5 grains of h-4198 behind the nosler bullet, and it showed promise, but the group opened on a third shot when i just wasn't paying attention.
the group. this time i paid attention. 3 shots from the bench at 100 yards, into 0.360". when you look to the picture, look to the top hole, as it is actually two bullet holes: at the bottom left of the hole you can see an elongation of the hole.
this is a "bragging-size" group, and is exceptional accuracy from any rifle.
the conclusion. this will be a "standard load." i have some more work to do w/ the sierra 130, as i think it will eventually group this well, as well. but, this load will become standard.
a rifle cartridge capable of getting 2650 fps from the muzzle with a 120 grain .284 caliber bullet and shooting a 0.360" group @ 100 yds is nothing to sneeze at. this attracted a bit of attention from some shooters, who shot the rifle, and all were pretty enthused about it. they liked it.
that's all good.

caption: the target is a plaster on a used papa murphy's take & bake pizza tray. it works pretty well. "waste naught, want naught." the trays don't store very well, though, and smell a bit funny. you cannot, however, beat the price. they make good targets.
update: i got curious the other day, and decided to see if a nickel would cover the group. well it did, so then i tried a dime. much to my surprise, the dime covered it quite easily. a dime isn't very big, about 0.704" in diameter. i figured that there would be enough "space" between bullet holes to account for that, but there was not. end update, picture to follow.
caption: the bullet alongside the dime is a nosler 120 grain ballistic tip, in .284 caliber. someday i will learn how to focus the camera, a small nikon "coolpix." it works wonderfully, except it doesn't focus worth beans. it will have something in focus, and about the time i get ready to shoot, it backs out to "fuzzy." it makes it kind of a game, i guess.
