Elderoo, the facts on a .22 rimfire are they loose on average 25% of kinetic energy and allmost the same velocity in the first 100 yards, at 150 the bullet drop is close to 24'', with the bullets energy down around 50 to 60 ft. lbs.,,, the shot he was speaking of was 200 yards farther, and done with out a rear sight on the rifle.
Thats about the same as loading your shotgun with a shot barrel (no rear sight),, full of slugs and hitting a deer 1000' away. I would have though it possible untill the 5 for 5 hits with no sight.
I agree with you on the .243, they are great for women, kids, or anyone recoil shy.
One of my favorite "farm guns" is the SKS, they are cheap, rugged, most are decent shooters, allmost no recoil, in the same power range as a 30-30, and cheaper to shoot than allmost any centerfire.
