Rounds wont fit case gage
Quote from Reloader on April 15, 2010, 10:23 pmI have what you could call a problem with my square deal. About 25% of the cartridges I produce will not fit in the 9 mm case gage. The bullet in question is a 115 grain .356 copper plated TC bullet. With other types of 9 mm bullets about 5% of the rounds won't fit in the case gage and that's OK by me. But one out of four rounds its to much.
I have no problems with the TC-bullet in my other single stage press, infact almost every bullet i produce with that press will fit the case gage.
I tested to size about 100 cases in station 1 and then I ran them through a case gage. Every case fited perfectly. After completing the three remaning stations I still ended up with about 20 rounds that didn't go in to the case gage.
Is this a sign of to much bell on the case? Or do I crimp them to much? Or to little? Any suggestions?
I use CBC (Magtech) cases (shot once) and federal primers.

For 9mm, max bullet diameter is .3555"

Strange enough it's the same diameter on the cartridges that fit the case gage and those cartridges that don't fit. In any case it sounds like I crimp these cartridges to much, right? Might perhaps even deformed them?
