Yeah, I tried the 120 NBT first (with Big Game) but it was just so-so.
Klik, thanks. No, I don't need itty bitty groups in this case. It's not a load for long range. I have 162's for that. Just opening my mind to the idea of running light and fast, since I'll be in open country and it's just a deer anyway.
I have a very good 140 NAB load that I've been running for years- if the TTSX's spray a 3" pattern (not expecting that) then I'll just default back to that. Pretty sure that'll work.
