Sorry I haven't posted in a while. The Peterson SRP works well with 107 SMK, 205m's or CCI-450's, 41.8-42.0grs RL-16. My speed with a 24" are 3100fps. I also tried 115 DACTS, but because of the short FB in my chamber I was only able to get a node at 39.0grs of RL-16. The groups were good at 100 and 200yds, but the speeds were too slow at 2862fps. Using 42.0grs H-4350 and the 107's works well also. But I need to try just a little more powder (42.3-42.5grs) to get the same speed an accuracy as I'm having with 41.8-42.0grs RL-16. Just a note, I'm using Lapua SRP brass also with the same results. I do like the pockets a little better on the Lapua though. Not by much, but you can tell at a quick look the difference. There is just a little too much champfer on the Peterson compared to the straight primer wall on the Lapua.Any update with the Peterson brass and 16?
