Im shooting a Mathews Q2 at 270FPS with a 410 grain ACC including the 100 grain tip. The bow groups tight out to 60 yds with field tips and rips a bullet hole thru paper.

Ive tested 2 different fixed blade broadheads, the Montec and Thunderhead, but both hit right about 4" at 30yrds and 5" at 40 yds.

Any advice? The bow seems tuned, the arrows spined correctly. I took 2nd in a 3D tournament with it today.
