I was shooting my bow this evening, as i do most evenings, and was shooting very well. Coke can size groups at 40 yds. So I threw on a new broadhead that i just purchased to get ready for the season. I bought the NAP HellRazor 100 gr. because i talked to a guy at the local archery shop, and he said they were awsome, so i bought them.
Now, to my problem. I shoot the Easton Epic 400's,with 2" blazer vanes. Now when i shot the broadhead, my arrow just kept flying upward and to the left. It was horrible. It wasnt even close to where I was aiming. Now i know a fixed blade broadhead isnt going to fly exactly like a field point, so what do i do? Do I need to sight in my bow according to where my broadheads are hitting? Any imput is greatly appreciated.
