Went to the range today to try out some subsonic loads. I loaded 10 of each different powder weight to find the best shooting one. I was using Sierra .30cal 220gr. RN bullets, new Winchester brass, Federal 210M primers, and TrailBoss powder, using my Savage 10FLP .308 w/ 24" barrel. I loaded them in 0.5gr increments from 9.5-11.5gr as per suggestions from the subsonic load page in the reloading section. The result were rather disappointing. With 11.5gr. I was only getting ~780fps and 10.5gr resulted in a stuck bullet which was thankfully easily tapped out with a rod. In addition to that my average velocities were all over the place with 50-80fps spread at times, even though I double checked all my charges with a beam scale and electronic scale. Not sure what's all going on here but it looks like I need to go back to the drawing board.
