Went out a shot my hunting arrows that I made for my Bear hunt, had to mess with a couple but now all are going where they should. Full length Carbon Express weight forward, 100 gr Brass inserts with 165 gr ACE broadheads up front for 600 gr total. After shooting them I spent some time on the deck putting an edge on them. Now my arm has no hair on it, or at best a lot less....lol!! So the Zipper is ready to go and I also shot my back up bow......a 2 pc Mohawk T/D longbow......it likes the carbons as well.
