When to turn necks?

[jaygorski]

If the necks on your favorite precision rifle brass like Lapua, Alpha, Norma or even Hornady are measuring from one side to the other .0003"-.0007"(NOT .007") at most, do you still turn those necks, I mean as long as they're fitting your chamber fine?

If you have less than .001 variation and they fit your chamber fine, then I wouldn't turn them.

If one could make about five or six very minute improvements in his loaded ammo, all combined to provide a meaningful improvement in overall accuracy - and this step were one of them, I'd do it. Then again, I'm a bit anal and I have time.

You may want to neck turn if using a bushing die and sizing 1/2 of the necks. The unsized part of the neck centers the round in the chamber. Just my thinking. No proof.

So what's your neck chamber size then? I'm guessing .276"?

.276" Thats my guess, the brass no lomger springs back. 19 firing, no annealing on the brass
