Finally got out to shoot some 160TTSX over TAC. I loaded from 50 to 51.5gr the best group was 50.5 and just a hair over 1" @2455fps. Worst was 51.5 at just over 1.5"(never chronoed this load)
I also took along my Benchmark load which is 48gr @2425fps and fired 3 quick shots with front rest only (this is normally how I shoot while hunting) and put them into 1". The 50.5gr TAC load is nice but I like the consistant accuracy of the Benchmark load and that 25fps vel loss means nothing. So I guess I will see what a 160TTSX @ 2425fps does to a whitetail this fall!
