Re: Velocity out of a 20" LTR with Federal GMM 168 gr.
Though a slightly different 20" barreled rifle, I fired my 700 AAC-SD with a 20" barrel over the weekend with some Federal Gold Medal Match 168 gr SMK loads. Unsuppressed, it choreographed 2630-2645 fps. Suppressed, it choreographed 2670-2680 fps. I was shooting just above sea-level. Temperature was 85*F.
