I have a Horton Legend 165# Crossbow. The 100 GR. Spitfire is what I have used for several years. I have killed many deer with these but if you hit a bone they will bend and youcan end up with a poor shot. I recently purchased some G5 Montec Blades after hearing how well they perform with crossbows. If they shoot well for me in practice I will use them this year. I do see that you are new to crossbow hunting. My suggestionwould be to try and take all of your shots at 20 yardes. I know Mfg. Tell you they are accurate at 40 yards and they are they will wound more deer at that distance than KILL them. I don't want your first crossbow hunt to end up with a deer you hit but were not able to find. If you usea quality cover scent and don't move around fast you will have no trouble with getting a CLOSE first shot. GOOD LUCK & Welcome !!!
