Just a quick update.
Saturday I killed deer #7 for the season with the Tac15 and Rocket Steelhead XL mechanicals.
I can't seem to help myself, and am constantly waiting for chip-shots.
It's not much of a long-range accuracy test when you're shooting almost everything inside 16 yards.
I'm gonna have to screw up the courage to take a 30-yard shot one of these days.
Still, it does not appear that the heads are opening prematurely and the blades are staying on for the most part. I'm getting the blade-breakage after they go through the deer and impact the ground. I.E. the exit holes all have all had 3-blade cuts, even on the bigger animals.
