[QUOTE="Mike027, post: 735573, member: 5816"] Hey guys Im hoping that you can give some advice on the next steps I should take on improving my handloads. Ok here is my story. In my pursuit of shooting tiny groups I went ahead and purchased an RCBS Case Master Gauging Tool because I wanted to verify the straightness of my handloads. As it turns out it would appear that I need to work on my bullet seating technique. I checked the bullet run-out on about 50 loaded cartridges. Im getting measurements anywhere from .002 on up to .009 +. About half were .005 or over. Im using 30-06 Winchester brass with Speer deep curl bullets. I checked the case neck run-out on several resized brass and they were all pretty consistent at .002 and less. I also checked the case neck on several fired cases and the run-out was consistently .002 or less. For years I struggled with golf because I practiced bad habits. I dont want to do the same with reloading so I figured I had best ask for some help. Does this sound like a technique issue or would it help to try a different a different set of dies? Im currently using the standard RCBS dies. I shoot a Weatherby Accumark and I can get groups below an inch at 100 yards but now Im concerned about the groups opening up at longer ranges. Also Im about ready to start reloading for my 7mm RM Sendero. Thanks for any input you have. I will also look in the archives for info on concentricity and run-out. Mike [/QUOTE]
