Glad to share. That photo, in my opinion, is a testament to how well put together the old M4-2000 cans are.
I've seen cans fail in most ways you can imagine. Luckily, (knock on wood) I've never been around a can that failed and injured shooter or bystander. Launching a whole rifle can or having one barf it's guts out is a very big shock, recoil-wise. Don't recall anything I'd consider a failure with a rimfire can, and only a few with centerfire pistol. Had an experimental piston in a 45 can with improper heat treat shatter in testing and throw the whole can downrange. Most failures were with centerfire rifle cans, and most were cases of " it almost fits, let's give it a try".
With that said, I can't count the number of times either I, or someone else, has left finger or palm prints on a hot can. Occupational hazard.
