[QUOTE="John Klingenberg, post: 2157575, member: 107749"] Well I'm on the road and the preliminaries are really promising. I've only tried one load of each bullet weight. The case is only filled to just below the shoulder with H322 powder so I believe theres a lot of room to grow. 33.5 gr of H322 10 shot average with Magnetospeed. 140gr Nosler BT. 2643fps 150 Sierra HPBT Match 2654fps 160 Sierra Gameking. 2606fps 36 gr of H322 10 shot average 110 gr Speer TNT. 3010fps Sub half MOA with the 160 grain bullets and 3/4 MOA with 150s. The 140s and 110s and 120s (i didnt chrono the 120s) were terrible, as in 3 inch groups. I havent even tried new powders, seating depths, brass sorting etc yet. I'm trying to formulate the best process to save time and primers of course for round two of testing. I did acquire a box of 162gr Eld-X I'm dying to try out. If at all possible to reach 2700fps with them the paper ballistics are really really impressive with its .616 bc. [/QUOTE]
