That's what I thought that my form was causing an issue. The thing is super jumpy it's a 10 inch octagon with that load you really got to hang on or you risk the whole gun ending up on the ground behind you..... I didn't even have bags I was shooting off a lead sled turned sideways with my sweater laying on it..... I would agree with the crimp if my deviation was higher or the range was farther but my deviation was acceptable to me and I can't crimp with the bullet set out that far my goal is 2.220 and I'm just barely off the lands.
