[QUOTE="killahog, post: 292738, member: 3722"] I see that you are using forstner full length sizing dies. I dont see a reason why you would have to run your brass thru a full length sizing die after each shot, what happens when you do that is the expander button in the case pulls the case neck and stretches it. This can cause a difference in case length, and it overworks your brass. This full length resizing may also be setting your case shoulder back farther than you need to be. If you was to buy a full length neck die you could select the proper neck tension with the bushings, and resize your cases without pulling an expander button thru the necks. I like to bump the shoulders on my cases back about .001 you can take the bolt apart on your savage and chamber the sized cases to get a feel for the proper headspace what you are trying to achieve is a slight pressure on the case shoulder. The bolt should not be hard to close but when you have just a slight tension your cases will be better alined in the chamber. RCBS makes a precision mic for each caliber that is helpful in measuring the shoulder bump, and it is very simple to use and accurate. The groups you posted are very Impressive and it looks like what you are doing is working pretty good but there is always more to learn, Check out that website you dont have to post there to learn the tricks of the trade there is a lot of good reading.
