What bow release do you use?
I just got back into archery after many years and never used a release. I finally settled on a Winn Free Flight C-10. It advertises a 15% reduction in felt draw weight, which I was sceptical about. Well, I tried it and I cranked up the bow closer to its 70lb draw weight, which now I have no problem drawing. So it really works and I am already grouping better. Much more confidence now, since I shot a broadhead into the tree directly in front of me while relaxing my draw with my original release!
