I started with a Barnes 250gr TMZ and it did well but when I tried a Hornady 300gr SST, it bucked the wind better and grouped better so I went up to the Barnes 290gr TMZ and its a nice flying bullet. My pics are too big to post and I dont know how to resize them but a 2" MOA @ 100yds with a peep is good enough for me. It has a boat tail so it is more stable and accurate over longer distances. Sorry for being redundant but in an earlier post I mentioned that at 150yds I can hit a paper plate consistantly off hand. This is with the TMZ. I use 110gr of BH209 to push it. The only real way to tell is to try them all......darn, more trigger time........
