120 gr ttsx with 51g of big game is running just under 3200 fps in my 24” rem 700. I have killed quite a few deer with this and the 120 gr nosler bt, and prefer the ttsx over 3k fps and the nosler under. I did have one of the noslers come apart on a doe at 70 yards at 3100fps mv. It hit the near shoulder as she was 1/4ing to me, and I found 3pieces of bullet under the far hide. She only went a couple of feet before sliding down the mountain in the snow, so I won’t call it a failure but I know I will get an exit withat that same shot with a ttsx at that speed.
