Need advice

This is what I do.

Separate out the brass that was fired in your bolt action, and the brass that was fired in your gas gun. Keep them separate for now.

If you have multiple rifles in the same caliber, you'll need to determine which one has the tightest chamber when setting your dies up.

Measure from the shoulder to the base of the case, on several of each of the casings fired from each rifle.
The shortest dimension from shoulder datum to case head is what you are looking for.

Typicially I set my dies up to bump the shoulder back 0.003 in a gas gun, and 0.002 in a bolt gun.

But what you are looking for here is 1 die setting that will work on everything You have in that caliber.

Full length sizing, returns brass back to minimum saami specs,
Brass life may not be the best, as the chamber may be between minimum and max specs.

I don't like working my brass more than necessary, so that's why I do the above.
I let the rifles chamber tell me where to set the die.


If you have any military brass, don't be suprised if you have to remove primer crimps to reload them.
They can either be swedged or cut out. And there are numerous ways to do them.
