[QUOTE="Michael Eichele, post: 288543, member: 1007"] I had a 300 RUM barrel with the same problem. After about 65 rounds down the pipe, I started seeing huge pressure increases. It got worse every day. I would back off powder and things would still be hot. Turned out it was a VERY cooked throat. This cause a lot of friction and subsequently increased the pressure. The 7mm RUM will cook a throat even faster. Sorry for the bad news. [/QUOTE]
