What would shooting that slug or buck shot do to the end of your barrels if you tried pushing it thru, oh lets say say a .040 choke or tighter?

I think I'll keep on doing what I've been doing for years with absolutely ZERO problems, shooting light recoiling, low pressure 70mm shells in 65mm chambers. I own a few guns with short cones, I shoot them often and I usually get around 10 to 15 reloads out of a single Remmy STS hull, when the hull starts crackin at the mouth (crimp area), its because I shot it to death, not because of the short cone. Do what ya'll want to do, at the same time I'll be doing what most other people are doing who've read the published material and have put many thousands of rounds down range with ZERO problems.
