steel mags =2 more lbs. 16 rds to the lb for long range match bthp ammo. 5-7 lbs of pistol(s) mags, cleaning gear, spare parts, holster(s) a lb of bipod, You can't keep the 308 viable unless you lug around nearly 20 lbs of gun gear, and that's WITHOUT any pistols. Pistol(s) their gear and ammo, add another 5 lbs or so. I aint wrong about this stuff, OR about the difficulty, likelihood of injury, of running, diving prone, etc, with too much wt on you. Fatique causes errors, proneness to illness, makes healing MUCH slower, etc.
