Hi

I have done somes shoulder bump with a redding body die and i have set this one a little to deep on my first couples cases.

I have bump the shoulder 0.007 more than a fired cases, so i would like to know if this is safe to shoot with this headspace ?

I would like to know what will be a good safe point compare to a fired case if thats happen again.

Thanks
 
Bumping the Should .007 is more like a full length resize. The instructions using the shoulder bump gauge would be to measure your first case, turn your full length die out one full turn, resize and measure. Now turning the die in 1/8th turn, resize again, and measure. Continue this process until the measurement on the bump gauge changes .001 to .002. Your resizing die is now set to bump this standard measurement every time.

If further instructions are required, send your email. The instructions can be scanned and forwarded.
 
Thanks horseman 2 and Ron AKA.

I have try to bump the shoulder to 0.002 like you have say Ron AKA but i have adjusted the die to deep.

I have checked the shoulder bump with this digital headspace gauge if someone is interested. I highly recomended this product, i found this very useful and accurate !

"...with this headspace..." Cartridges don't have headspace. No matter how that guage is marketed. Headspace is a rifle manufacturing tolerance only.

You are right. A cartridge can not have headspace on its own. But a cartridge that is bumped back .007" from a fire formed cartridge will have .007" clearance in that same rifle. Therefore the OP was wondering if .007" headspace is too much and if it could cause problems when fired. But thanks for your useless post just to increase your post count to an even higher astronomical number.
