[QUOTE="liltank, post: 255035, member: 13275"] I have a .308 comp chamber in an 18" tube. I'm currently running 165 SST's at 2450 using 41.4grns RL15. My 300WSM w/ 208 A-Max's are only getting 2700, but I was having some chambering issue's. It has been opened up a little and the head spacing backed off, so I'm hoping for less pressure, more powder and faster speed. We'll see, haven't gone out. Temps in the neg. #'s. :rolleyes: I consider those slow compared to the 220 AI. :D [/QUOTE]
