Como o por que

[knucklehead0202]

Redding Competition Shell Holder Set contains 5 shell holders that are incrementally taller than standard in .002" increments. You start with the +.010" shell holder and proceed down until the desired headspace is reached. I'm currently using the +.004" shell holder with my die set.

I'm not comfortable with bumping the shoulder back only .002" for a semi auto. Cases spring back to various degrees even within the same lot. You want some wiggle room there.

Sounds like an expensive replacement for adjusting your dies. Of course I may be the fool for blindly using "standard" shellholders all these years....
