I am using 120 gr ttsx at .05 off the lands over a nosler book max load of big game powder. Pushes both the 120 gr nosler bt and the 120 gr ttsx at just over 3200 Fps out of my 700 ss sps, with the bt a little more accurate. I use the ttsx on deer as the bt gets a little violent on the close shots. Both are under 3/4" for three shots at 100.
