So after building my first form 1 can for my .308 last year, i decided to make another for my .223 AR and bolt action. I may have made a small oops and figured id ask while i can still just toss it an make another.
I was putting the finishing touches on the end caps, and i was putting a slight bevel into the muzzle end of it (muzzle as in where the bullet exits not where it threads onto the muzzle of the rifle). Apparently, the bit was a tad loose in the tool holder and when i put pressure onto it to take off material it moved, increasing the angle of the cut. I didn't realize until i made the full pass, and the metal around the hole is very thin, right at .030.
the inside of the cap is flat so obviously that is the thinnest point. Is that way too thin or would it be safe? My thinking is by that point, the pressure isn't nearly as great as what happens in the blast chamber portion. Will this be safe to stick with or should i just junk it?

Re: .223 endcap thickness
What's the dimensions of your can and what material for the end cap? If its 1.5"x5" versus 1.5"x12" my answer will change. All in all, I personally think its a tad too thin. I'd want 0.050 or so.

Re: .223 endcap thickness
I'd go thicker. Call it an Oops while making the can. The can is not yet complete so destroy the part according to ATF recommendations and make another one to correct specs.
