[QUOTE="Jim See, post: 2189636, member: 69519"] Agree with Alex on this, has been more common recently with some brass manufacturers making case heads .175-.185" thick. We could easily tell if this was the case having the barrel in hand and doing some measurements as well as inspecting the brass. Since this thread is 2 years old i doubt that will happen. The failure point was the brass, it failed to contain the pressure, the reason it failed is unknown. I'm not sure you can put enough varget in a 22-250 to rupture a case head in a well assembled rifle. but an unsupported case head can rupture and cause this with a normal charge weight.
