I went out and shot my Magnus heads last night..... At first they were grouping about 5 inches to the right...... I expected that b/c I knew my arrows were a tad weak. I went back in, and cut just under and inch off and then glued them back on. Went back out and those things were flying like darts....... I don't know if this is possible, but I think my broadheads were flying better than field tips........ I'm cocked, locked and ready to rock!!!! Come on October 1!!!!!!!!!!!!!
