Worst I've ever shot was my son's NEF 12ga single with 3" mag turkey loads. My son, a friend, and I were shooting and we tried the 3" in my Winchester 1300 and my friend's Mossburg 500. They were barely different than the skeet loads. I tried one in the NEF, figuring it would be no big deal. My son pulled the trap, I fired, and when he looked over at me I was gone. It stutter stepped me back about 2 feet and nailed my index finger on the trigger guard and my middle finger on the back of the trigger guard. I was shaking my hand out for several minutes (my shoulder wasn't too happy either) Of course, when I offered it to my friend he tried it too (wouldn't we all?) and the same thing happened to him. My son was a bit smarter and wouldn't try. I fired a .454 and though it definitely lets you know it's there, it just feels good. I get much more muzzle flip from my wife's H&R topbreak in .32 S&W short. One other (useless) weapon I shot was a Remington 760 carbine pump action in 30-06 with a scope firing Winchester 220 gr Silvertips. That thing is too short to be accurate, too light for that round, and the pump action and short barrel would be for close woods range, but the scope would slow you down too much to use it for that and '06 isn't the best short woods cartridge. We had a slip on Pachmeyer recoil pad on it, so it didn't hurt, but it put my soulder back about 7" seated and leaning into it. Compared to that, my Czech Mauser 8X57 is a BB gun.
