I have an xp-100 in 350 rem mag with a 12" barrel, that I thought was pretty bad until I shot my contender with 10" tapered 45-70 barrel installed ( old style wood grips and no muzzlebreak)and hot loads. and I had a ruger super blackhawk with 7.5 barrel that just wasn't fun to shoot alot, using max 300 gr loads. but the worst thing I've ever shot was a american derringer in 45-70, with the small half moon grips. the barrel on it is only 1" longer than the cartridge. I grabbed the wrong loads for it and didn't realize it until I sent a very hot 450 gr., ruger #1 load, down towards the target. it took about 10 minutes to get the feeling back in my hand, once I got all the bleeding stopped. then the hand went numb again---right before they stitched it up. one shot was enough for me. I still have the derringer and it still has only one shot thru it. everytime I think about shooting it again, I just look at the 2.5" scar on my hand and that feeling goes away. jim
