Very interesting test "DPris." Thanks for the info on the patterns. I didn't have enough ammo to really do a thorough testing. Just did enough to get a general idea.
"WV-Gunner" yes I agree with you about barrel length. But if I'm going to carry a gun with an 18" barrel it's going to be either a shotgun or an AK, and I'm pretty sure either will solve any snake problems - even a 30' anaconda. LOL
As for whoever mentioned shooting a snake at 2 or 3 feet away - it ain't gonna happen - if a snake is that close to me I'm going to be jumping 5 feet into the air, running! I'll shoot it on the return trip after I clean my shorts.
