Being a pump design, my Rem 7600P can shoot pretty much everything .308 that would feed into the chamber. I'd like to exploit this versatility for a "one-rifle for all occasions" project.
A standard 150-168 grain .308 is generally considered an overkill for HD due to over-penetration, especially in urban area. Even for short-range general SD situation the standard round is not optimal, since it is designed to deliver energy efficiently to much longer range. The shooter pays with a relatively heavy recoil - especially in a light (7 pound) rifle.
That recoil, not to mention bang and flash, cost the speed and accuracy of follow-up shots which is important at close range.
I believe a loading was developed specifically for police that uses a light (115grain?) bullet at higher velocity, to be used with low-recoil at relatively close (iron-sight, 0-75yds) distances. That sounds interesting - as a fast 110-130 grain bullet might actually deliver greater energy at close range and at much reduced recoil than a standard round.
I imagine, M1 carbine bullets can be used for such SD purpose. Would an M1 bullet out of 7600 be under-stabilised or over-stabilised?
Anyone tried anything like that or read anything relevant? Any recepies? Suggestions?
For HD, a lighter powder loading with a relatively light bullet can be developed - providing sufficient energy but further limiting recoil and especially over-penetration. Some kind of a HP or round-nose lead bullet would be preferable, but I imagine a regular bullet can be loaded backwards - maybe even with a small indentation/cavity drilled into the exposed lead of the base.
Basically, an AK-type loading (7.62x39) or even M1 type, but with more radically expanding ammo - from a .308. How about that?
