Shoulder Bump tolerance

[ChuckSwagger]

Hello,

I am new on rifle reloading.
My 308 Win Whidden Custom Chamber Full Length die was set to give me 1.610 shoulders bump and the vast majority are in this size (42) some 1.609 (9) , but there are some Brass which got sized to 1.608 (7).
Which shoulders bump sizes differences do you accept to use for precision shooting?

My press is a Frankford Coax and I am using once fired Lapua Brass . My fired brass measures 1.612 shoulder bump and the bolt works easy when the shoulder bump it is set to 1.611.

Thank you in advance!
Bruno

I bet that those reading .002 shorter were actually .002 shorter to start with.

I wouldn’t worry about it.

Don't guess at it and go with what "feels good". Find out what your actual headspace and bump the shoulder .001-.002"

.002 Is better that average. If you want to get OCD. You can sort them

If it’s within a thou or two I’m GTG.
