What thickness & grade of steel did you use for your Buff. I have a piece of 5/16 mild steel that is 9 x 16 ft that I am contemplating cutting a life size buff out of it for just cast bullet (1600 fps max prob.)shooting at minimum of 700 yrds but hopefully 1/2 mile.
My original plan is to cut the thing into joinable sections of under 100 lbs each so it can be relocated easily by a couple people with a pick-up. I'm sure the slugs wont penetrate that thickness at that range but do you think they will pock mark it ??
Mine is 1/4” mild steel, and stops cast bullets like nothing. With enough hits it starts to curl up a bit, which is easily fixed by turning it around. It’s only been flipped once in quite a few years though.
It is easy to move by throwing it on a sled trailer. A couple of strong guys can carry it a ways and hang it. When it got turned an enterprising friend clipped a vise-grip at the balance point, hooked up a come-along, spun it around and did up the chains again. Did it himself, sort of one of those work smarter not harder kind of things.
