Home Forums Reloading Big Game Rifles 708 loads using Horn 139sst

I load ssts in 3 rifles. Still working on one but the other 2 rifles would not shoot sst’s close to the lands. In one I know 0.060 off and other i think is around the same or there about. I shoot 708 xbolt with 139sst but I use varget/42 grs gives me 2775. I think last 5 shot group give me ES of like 3 using lab radar. Inch groups at 100. Working with big game/47.5 grs added another 100 fps but accuracy wasn’t great just decent. I think this gun likes the ssts but just don’t love them as it took a lot of effort just getting these one inch groups with varget
