Are you sure you weren't shooting 45 colt shells in a 454 casull gun? A 454 casull ain't a big fluffy pussycat. It makes a 44 magnum look like a little girls gun.
I made/am making a steel target out of old rail road plates. It's a bit of pain plugging, welding, and grinding the 6 or 8 3/4" square holes in each plate. So, 150 grain SP 7.62x39 out of SKS from 40 yards left small craters, 9mm Makarov left only a shiny spot. View attachment 454449
Did you have equal grips on both guns? A set of rubber grips and wood grips on one gun makes a big difference. I have wood grips on both guns. Was the weight on both guns you shot close to the same?Oh, I agree, but shoot that .375 JDJ and get back with me. Just a couple of rounds should do it.
Yeah, I don't plan on shooting it with .270 win or 7.62x54r, but just for .40 s&w and 9mm Makarov. If it starts deforming, it's ok, I've only got maybe $1.00 in it, in grinding wheel. I lucked into 40 lbs of 3/32 6013 for $4 at an estate sale. Would have preferred 6011, but at that price, I couldn't not buy it. The plate is probably close to 5/8" at thickest point and about 3/8" at the thinnest, and was free.

I'll talk a buddy into shooting it first. If it break his wrist or give him a concussion then I'll shoot it.
