Thanks for all the input. All the loads were 3", and I have a cantilever set up, so barrel movement shouldn't affect the accuracy. I'm going to try the Hornady's and Lightfields this weekend, as they seem to work well for a lot of people. I also agree that flinching was probably a significant factor. What is a good solution for that with my setup though? I have a friend with a Lead Sled, and so zeroing in shouldn't be a problem if I use that, but I don't want to blow the truly important shot at my dream buck because I flinched. Any suggestions?
