I just started using a concentricity guage. My full length resized brass has excessive runout of between .007" and .012".
The only good news is the fired rounds are about .002" and some less.

Have any ideas how to straighten this out?

Re: Concentricity

What were your hand load group sizes before you checked the concentricity?? If they were small proceed to step A, if large proceed to step B.

A. Stop using the concentricity guage.

B. Stop using the dies you have (or do a very careful setup and die check). Buy some competition dies or Wilson neck size and seater type dies. Proceed to step C.

C. Stop using the Concentricity guage. [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img]

Re: Concentricity

As crowded as the ranges are becoming, that's probably the best advice. The groups are probably good enough for most hunting situations, and I can fine tune in the spring.
The 6.5-06 groups between 1 1/2" to 2" @ 200 yards.
And the .270 groups about 3" @ 200 yards.

Re: Concentricity

FWIW I have a concentricity guage too but nowadays it only clutters up a reloading gear drawer... looks neat in there but it's now a "leaverite" device.

Re: Concentricity

If you use a bushing die like a redding S
die it will be a problem no more. most
runout is caused by oversizing your brass,
by using the correct size bushing you only
size as much as needed and wahla your concentricity guage flatlines.
p.s. then use a "BR" or inline seater
(a BR or inline seater wont make it any
better just keep it from getting worse like
a standard seater will)

stray--sinclair sells blanks with only a caliber size hole in it--all you have to do is run your own reamer in [img]images/icons/wink.gif[/img]
