[QUOTE="scrmblr1982cj8, post: 1120558, member: 69799"] I think you are using too much powder and I'd recommend starting over with your load. The photos show the brass you are using is NATO brass. NATO brass is great, and I've got thousands of rounds the stuff. NATO brass has a smaller internal case capacity compared to commercial .308 brass since it has thicker walls than commercial brass and has to hold up in belt-fed machine guns. I always start 2 grains under the recommended starting point for any powder and work up. Looking at the Hodgdon website, 45.0g is the maximum recommend load. Since you are using 43.5, I'm thinking that you've exceeded the pressure ceiling for the brass/powder combo you've chosen. Also, take a look at your seating depth, since bullets seated deeper into the case will increase chamber pressure. I've found a load at 42.5g Varget for my R700 AAC-SD. I won't try anything higher.
