I have shot nosler E-Tips, Barnes TSX, TTSX, and LRX, and Hammer Bullets, all have performed very well with only a couple follow up shots needed in over 25 animals in Commnifornia. Longest deer was 625 with a .270win and Barnes TTSX. I definitely say push them fast. I have whacked a lot of critters with my .270wsm pushing 110 TTSX @ 3470fps. As well as my .243 pushing the 90 E-Tip @ 3120. I have yet to try the Hammers on Game because i just got them a few weeks ago but so far load development has been minimal and groups have been tight. I have only recovered a few bullers, most punch a nice hole through critters no matter what you hit or how fast the impact velocity is. Put the bullet where it needs to be and you will have meat in the freezer.
