Hello, I am a long time shooter but, new to crossbows. I got my 15i yesturday and already have it sighted in up to 60yds. other than some minor issues I really love this crossbow. Very acurate for a bow and plenty of energy to harvest a deer past 50 yds. I sighted mine in w/ 100gr field tips. I was going hunting this evening and would like some advise on broadheads. I have NAP Shockwaves, NAP spitfires - both 2 and 3 blade, & Muzzy MX-3's.
