And a threaded barrel on 6.5CM is meaningless, not like there is any recoil with that cartridge in a heavy 26" barrel rifle.
I filled the hollow butt of my 12FV with lead wheel weights and silicone caulking, weighs about 13lbs now. Stock is pretty comfortable so I'm trying to make it work rather then replace it.
Not true, less recoil is less recoil. what is easier to see your hits on through the scope? A 17HMR or a 308? I can tell the difference between a .17HMR and a .22lr. Maybe on a 20lb+ rifle you couldn't tell. I can tell when I take my brake off a 10lb 6.5CM rifle.
