I picked up my 30p-1 a couple weeks ago after an excruciatingly long wait. Went to the range shortly after picking it up and shot it on my R&D precision 308. The gun was a consistent 1/3 moa gun since new. My first three 5 shot groups with the 30p-1 were all 1/4 or better. Sound suppression was excellent and recoil was slightly less than unsuppressed. This past weekend I got a chance to try the thunder beast on my newly finished 300wm. It was a little louder than the 308 but still very quiet (22 inch barrel). Accuracy was excellent but I was amazed by the recoil reduction. Granted this is a 14 lb gun but the 30p-1 brought the winmag down to 308 gas gun levels. I could literally shoot this gun all day. If you're on the fence with the 30p-1 300WM combo, don't be....works great.
