[QUOTE="PLHunter, post: 1577926, member: 107772"] Okay some more information from today’s shooting. This time I loaded up some 104 grain hammer hunters with IMR 7977. The following are my results: 57.4 3256, 3187 58 3236, 3267 59.5 3364 59.7 3387 60 3405 60.2 3492, 3442 As you can see I had some crazy extreme spreads. I may retry with large rifle primers just to see. The speeds reached were above expected. I wanted to hit 3400 FPS but didn’t expect to hit it so soon. Recoil was light and no pressure signs were seen. Barrel temps were much better than with the 121 and imr 8133. I also tried some cutting edge 115’s with the powder but velocities were all over the place. Just as a side note 80 grain Barnes with RL-17 was at 3690 and recoil was like a .223. I did shoot the 121 hammers for group at 205 yards with 60 grains of 8133. 3 shots at 1.6 inches. Light 5-8 mph breeze. I had two 59.5 grain 7977 104’s availableand a 59.7 that I shot for accuracy at 205 as well. Group was 1.8 inches. Both groups had 2 within 3/4 inch and one “flyer”.
