TAC looks very promising with the 160 TTSX as far as speed goes. From my chrono tests, it gains about 60fps for every 1/2gr increase in powder. At least from 48 to 50.5 gr. Now the question is, how well will it shoot? I hope to find out next weekend. It has to shoot inside of 1" for me to change from 48gr Benchmark @2825fps which shoots inside 3/4" pretty consistently.
