1. Don't reload plated brass, unless you're going to use it in a "dangerous game" rifle (where the "slick" plated case will generally feed better). Do you really want that crap going down your barrel?
Try FL sizing for minimal headspace - Screw your sizing die out, then in in small increments until the case will chamber. Lock it down. Try a Redding bushing die to adjust your neck tension.
