but what kind of heat treating did they get? if the gun is only proofed/designed to take the industry average of 125-150% burst strength of the standard saami 45 colt or .410 shotshell, then anything in the ruger only section, even with minimum loading data will turn it into shrapnel.
If not immediately, then sooner or later, yes. That's exactly what I wondered, and this is exactly why I asked.
Am considering giving H&R a call and seeing what their technical people say.
