In the last two years:
700 VLS in 308 with plastic stock*-variety of hand loads
308 Sps ss sporter*-178g Hornady Tac ammo
308 sps blued sporter*-178g Hornady Tac ammo
223 sps ss sporter-Benchmark with 55g Nolsers, unreal accuracy
Tack drivers with no alterations, guns with the *
These belonged to friends
The 223 Sps ss I bought, I put it in an old Walnut stock, bedded, freefoated, tuned trigger, and it shoots 3/8"-1/2" with a variety of loads.
There is no perfect world, spend according to your patience level.
