these varying rim thicknesses are driving us batty

The gun is a standard 44 magnum but the rim thicknesses vary from .051 to .068 on 5 different brands of brass. So now comes the problem of setting the headspace with that much variance. I told my guys to pick the brass with the thickest rim and set the headspace to that. I will have to tell the owner to only use that particular brand of brass. If we set the headspace with the brand that is the thinnest then we get rubbing on the recoil shield if he uses any other brand. I sure wish the ammo and brass makers would get their acts together and stick with the SAAMI specs of .055.
