Got a Savage 12FV in 6.5CM last fall and been having a problem with it destroying cases as I work up loads. About the time I start getting near the middle of published data it starts stretching primer pockets. Today I was finally able to set up the crony as the snow drift is gone in front of my shooting bench and I found out I was pushing my bullet about 150+ fps faster then what it should be. What the heck is going on? Max load for 130gn ELD is 44.8 gns of Hybrid for around 2800 FPS and I'm getting 2850-2900 with 41 grns of powder and .020" off the lands.
