Hey guys I need some advice!!! I am going to Africa in May and all advice says I need to use fixed BH's. I have used 80 gr mechanicals for 3 years and had great success with them on deer. I just switched to Wasp 125 gr 3 blades fixed BH's. The problem is that I can't get the BH's to group at all. I re-sighted my bow with 125 gr field points and had no issues at all....very nice tight groups. When I switched over to the BH's I was lucky to get 18 inch groups from 20 yds!!! I had arrows flying all over the place.

This is my first experience with fixed BH's and I'm absolutely at a loss....Any advice??
