Increase in rejects

I am getting an increased percentage of rejected finished loads due to cases not fitting in the case gauge (.40 S&W). I went from 1 and 20 rejects to a 3 of 10. Is my forming die worn or did I get an exceptional bad batch of used reloading brass? How do I check?

Thanks

RE: Increase in rejects

A carbide handgun sizing die should be good for 60-70,000 cases. Try adjusting the die down to touch the shellplate, then back it up 1/16th of a turn. See if that helps. The narrowest inside diameter of the carbide insert should measure .417" +/-.0005"

I was having the same problem.  I switched to a Lee carbide sizing die and the problem went away.  I resized ~ 300 cased last week with zero failures.

I ran into the same issue on 45 ACPs. I ended up lowering the crimping die ever so slightly and my rejects went to near zero.

RE: Increase in rejects

Hate to say this on Dillons forum. Let it be known I use all Dillon dies with exception to the crimp die for this exact reason. Get yourself a LEE carbide factory crimp die and you will never have this problem again. It will resize every round as it is being crimped. If it goes through the die it will chamber correctly.
