zzt,
Concur. When I said my compensated barrel, I meant the barrel in my other PCC. It is a 16" barrel turned down to 10" with ~8" of rifling 2" of comp made by Bevin Grams. It is in a 16" tube to keep it legal. I will start with my loads from that gun but I have other stuff to try also. It may be coincidental but I have really come to like 1200 FPS loads. My timing on moving targets has been the best is has ever been and steel does fall. The carbine that will get the buffer currently has a Taccom ULW barrel. I will see how it works but I will also try a 16" JP barrel that I have. I really want to keep my current PCC intact, at least until I have proved to my self that the RDBS is better for me.
Thanks again,
Chuck
