[QUOTE="Buttermilk, post: 769946, member: 5262"] I have a 30-338 WM that has a tight chamber. Virgin brass fits and fires just fine. Unable to locate 338 WM brass to neck down, I found some 7 RM brass in both R-P and W-W brands. Been necking this up to make the 30-338. Once fired brass (7 RM) from my own 7 RM Browning rifle and once fired from the local range will not fit my chamber even when full length resized. Inking a case and inserting the case into the chamber as far as it would go revealed where my chamber is snug. My chamber is snug on the front end, based on where the ink was rubbed off the case. Taking measurements of the cases that don't fit and of virgin brass also confirm that the shoulder area of my chamber is tight. Perusing thru my reloading manuals at case drawings leads me to believe I might be able to use a 8mm Rem Mag or 7 STW "body" die modified in length to resize the shoulder area enough to get these once fired cases to fully enter my snug chamber. Lee offers a 7STW body die that would need shortened/modified on both ends. An 8mm RM body die shortened enough at the base would likely work better. Regards Rog [/QUOTE]
