For the most part do you try to have the least amount of neck tension so the release of the bullet will have the smallest variance??
Is .003 to much grip on the bullet to help with ES or if no mater the tension as long as they are uniform from neck to neck can you control ES.
bench said:What are the effects of neck tension,does it help make a load more accurate or are there other effects as well.
I have three different dies for 308 and the all give a different neck tension and would like to use one that helps the load the most for target shooting....

Thanks for the help

I can get the same degree of accuracy/precision, but at least to me, this sounds better than it actually is.normmatzen said:If you can use a standard LEE neck sizing die with your caliber, you can increase the bullet grip by "polishing" the mandrel in the area of the collet. You can buy extra mandrels for not much money and make a bunch with different end neck diameters.
Of course, you can do this same trick with a custom LEE die, as I do with my 6BRX. Right now I get 0.00075" consistently for long range BR. By consistent I mean an SD of 0.00026" on the sized case diam.
