[QUOTE="Fred Ea, post: 626836, member: 43009"] My brother was fire forming brass and lapping the barrel in his 7stw this afternoon and he had a case separate on him and another case that was suspicious. He loaded up some rounds to Lap the barrel and loaded so new brass that had not been fired yet and had a complete head separation and two more that had blown out to .524 above the belt, so he stopped shooting. They were loaded with a light load- 68.0gr. Of IMR7828- 140gr. Bullets. Would this be due to the load being too light, excessive head space, or a over sized chamber? The barrel is the factory Remington barrel on a model 700, he bought the gun new and took it straight to the gunsmith to have rechambered, never fired the gun before having rechambered. Anybody have any ideas what the problem may be? Any words of experience would be appreciated, haven't had this type of problem before. FElightbulb [/QUOTE]
