Exactly what sort of signs do primers give to indicate a slight undue pressure. Im guessing that they begin to work themselves out and leave an action "fingerprint" on them but outside of protrusion or being blown Im afraid I need some info on this matter. I usually have just gone with middle of the road published loads but would very much like to learn how to perfect a load.

Thanks, Byren

There are some very good photos of pressure problems on my reloading page, table 3.

It will also depend on which primers you are using...some are "harder" than others. If you see signs of pressure on the primer you are already way too far.

excuse my ignorance, mr. ricciardelli, but is there a web page where I may see those pictures?
tks.
