neck thickness ?

[Gman]

My chamber neck for my 6BR is .271. I don't turn necks. I use only Lapua brass.,all same lot #) I have a new Redding case neck gauge, and I am wondering what is considered acceptable variances. I just checked 25 cases,,after bumping the shoulder, neck sized, de-primed, primer pockets clean, and case mouths chamfered in & out, no cases needed trimming) Out of the 25, 20 are less than one-half of .001 difference, and 5 are almost at .001. Can I assume the 20 cases are acceptable for match shooting, and the other 5 cases should be used for fouling shots? Is this the way to segregate the good cases from the "not as good cases"?

What kind of match shooting will you be shooting Gman?

 

[Gman]

I plan on trying to shoot some Groundhog matches this year.,100, 300, 500 yards) I have never shot any kind of rifle match in my life, but I used to shoot trap competively years ago. I am looking forward to it.

Gman check your pm's.

You have excellent brass. Use the looser spec stuff for the short range. Let your targets tell you how to segregate brass.
