was always a fixed blade user. my new bow would not shoot well at all with my MX4 i had from all set up.. as suggested on this site i tried the grim reaper 100gr. like throwing darts. and have taken 2 deer with them and the farthest the doe i just shot on saturday only went 50yrds.. huge exit wound! looks like a one ounce shot gun slug went thru.. and she was 1/4 away pretty good.
