I'm in need of some help to understand the root cause for this barrel failure on a Sprinfield gi 1911.
Firearm; Springfield GI model two months old. Modifications to firearm are; Installed wilson commander hammer and beavertail. This Springfield has worked perfectly until now.
Ammo; Reloads; Federal brass, 230gr cast bullets, Hodgdon universal powder @ 4.6grs, Fedral large pistol powder. COL @ 1.245. Approximatly 5000 rounds reloaded to date with absolutly no issues. All round have been extremely consistant. I have reloaded for my other firearm for the last year with absolutly no issues. Extremely pleasd with the performance of my reloads.
Situation: I was participating in the local pistol club steel target shoot. On my second station, third shot in a round of six. Third shot fired normal. Empty shell casing did not eject. Barrel locked up in the barrel bushing as the slide was cycling back to eject empty casing. Firearm was take apart on site. Barrel was found to have buldge in the end under barrel bushing. When measured the buldge was.030 larger in the failed are. Basicly the barrel had balloned out in the area just behind the critical area of fitment between the barrel and bushing. Needless to say that the barrel bushing will not slide on to the barrel more than about 1/4 inch. This barrel is trashed. I'm confused as to what my have caused this type of failure.
Any thoughts on this situation would be great. Thanks in advance!
