[QUOTE="Capt RB, post: 1539837, member: 85987"] When you reload for the first time after firing in your chamber you have a match to it's dimensions. In the past I would just use a lee collet neck sizing die for my match rifles. Today I will set up my die to push the shoulder back .0015-.003. I run .0025 neck tension in just about every rifle I own except the lever guns. The advantage is your not wasting any energy pushing the case to form to seal your chamber. Done right you can get very good characteristics if you have optimized your given load to your barrel's harmonic mode. Start pushing the shoulder much more than .002 and your losing energy again which can show up in excessive deviations in velocity which will show up vertically on target at distance. [/QUOTE]
