Highdesertwolf, you might be wrong here. It depends where he hits his lands. If he hits them at 2.857" with his ogive then he would be fine and dandy with that light load. My 308's hit a 2.83" and 2.8" (in a custom throated barrel) with 165gr gamekings and TSX's hit them at longer COL's due to the aerodynamic shape. Sometimes going past SAAMI COL specs can lower pressure/Velocity. Then when you get close to the lands, you start getting pressure (hence velocity). And vise versa, the deeper you seat, the more it can raise pressure. Its a give and take game. When You push a bullet out more, you are giving more space in the case but less jump, and vise versa. I did alot of experiements with my 300RUM's on this. I found I could load up to compressed loads easily at 3.67" COL, where SAAMI says not to go past 3.6. If I loaded to 3.6 with this load I load at 3.67, I wouldl lock the brass up in the chamber. Then as I reach out to 3.82" COL, same thing would happen. Now this was with 200gr Nosler Accubonds. Long Ogive.
