Hey there JM. We might be able to market that thar rifle! As for broken glasses from a recoiling cocking piece, I think maybe those folks could use some marksmanship training on how to hold and shoot a rifle. I've seen quite a few case failures and have NEVER seen any kind of catostrophic failure with a LE of any description. That's in 35 years or so of reloading and shooting them. Of course, I've always been a quality not quantity reloader. Brian
