[QUOTE="J E Custom, post: 1513272, member: 2736"] First I would recommend checking bullet jump (If you seated against the lands, pressure would/could be to high for that load even though it sounds OK). Chamber dimensions can be different than book COAL dimensions and need to be verified. The other thing that could cause this is not enough neck clearance. Measure the loaded diameter of the neck and then measure the neck diameter of a fired case. The fired case should have a .003 to .004 thousandths larger neck diameter than a loaded cartridge. (This is required to release the bullet without pressure increasing). Just something to look at J E CUSTOM [/QUOTE]
