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
