been shooting 150gr of 777 with TC 250gr sabots for nearly 10 years outa my TC Encore 209x50. Well this year I went and changed to 100gr 777, shot 4 @ 100 and 4 @ 200yds. groups were much better. Now I have never missed a deer with this with over 30 kills. Sat. I took the knee out of a doe @ 145yds, why? Because I did not track my trajectory from 100 to 200yds. Back tot he drawing board and glad it wasnt a nice buck. Reason for such business is I have some neck issues and it really hurts at times with that much kaboom. Any suggestions?
