early on when i acquired my ar-15 upper in 6.8mm remington spc (special purpose cartridge), i also acquired sevearl boxes of remington ammunition for it, and some from hornady.
no surprises from the remington when it came time to reload it.
by contrast, a rather unexpected turn of events happened with the hornady expended brass.
as expected, and as noted in my speer reloading manual, the remington brass came with large rifle primer pockets, into which after depriming and resizing the case, on inserts large rifle primer caps. in my instance, i replaced the old spent primers, once removed from the case, with cci no. 200 primers. and, as per usual with remington cases and speer primers, no problems.
such was not the case with the hornady empty brass. imagine my surprise to find out that the primer pockets in the brass were sized for small rifle primers, and that the brass, made and marketed for the private commercial market, had primer pockets crimped with a military crimp. this made reseating new primers virtually undoable, and before i will be able to reprime and reuse the cases to make more ammunition, i am going to have to go to the expenditure of considerable labor in swaging the primer pockets and reeming the rims to remove the old military style crimp.
this comes under the heading of "tedium," and "major pain in the butt." it is not something i enjoy doing, an unless you are really into tedious labor, i would avoid hornady brass or ammunition unless it comes with a large rifle primer as does the remington brand ammunition, and component brass.
i do not know hornady's rationale for so equipping their ammunition. if any of you do know, i most surely would like to learn why they have done this, and would appreciate you so informing me.
