BUT everybody that I talked to when looking at what to spend time developing for my 6.5c gas gun, most people said in the gas guns stick with the lighter weight stuff. Im shooting a 123g AMAX at 2900fps out of my JP barreled/JP high pressure bolt, gas gun. I havent played with the heavies at all because, for me, the 123g does it all out to the 1200 yards I have available to shoot on.
