I have a trued Remington 700 SS action with a 26" Bartlein M24 contour 8 twist barrel in an XLR carbon chassis, and I'm shooting 75 gn. Hornady Match HPBTs into a 1/2 MOA at 100 yards with 5 shot groups. I'm looking to improve on this with another bullet in the 75-80 gn range. What are the competition guys running in this chambering? I know this rifle can shoot better than 1/2 MOA. I have a 308 that I can shoot in the 0.3s - 0.4s, so I know that it isn't me. I shoot paper at 100 and steel from 300 to 600. I tried the 75 gn. A-Maxs, and the rifle didn't like them.
