[QUOTE="Kiwi Nate, post: 1096727, member: 8533"] Sorry for these ongoing rerplies, I am only just reading past questions. Regarding the 30 degree shoulder, it has no bearing on how prepped brass chambers. Simply neck .300 brass to 7mm and away you go. If your ammo does not chamber, either the chamber is out of spec or more than likely, you have bumped the shoulder or stressed the case in some way during neck sizing and expanded the case body. The fix will be to run the cases through a .300 or .338 Win mag body die as the tight spot will be just behind the shoulder- not at the shoulder. I named the wildcat the "7mm Practical" because it is supposed to be an easy straight forwards proposition, not an ordeal. So try to keep this in mind if such problems occur. While we are on the subject of simple and practical, I should also mention that Lee currently have sample cases for the Practical chamber and can make collet dies if anybody wishes to utilize Lee custom neck collet dies for the Practical. Hope that helps. [/QUOTE]
