Well I tryed today and had good success with a couple new bullets and full length sizing may have something to do with it I think I might buy a better neck sizer what kinda is good for the price I'm not a benchrest shooter but want a quality product I was looking at redding and rcbs I have a Lee and well it works but that could have been some of my problem thanks for all your in put had a good group with a medium load of varget and 50 v max but best with some nosler shots bulk bullets and midsouth black tips all 50 grain tryed 53 vmax some of the worst groups I've shot with the gun like 3 to 5 inch lol I think the powders were 4895 and 4831 anyway lyaman I don't think makes a neck sizer for a swift thanks
