I have started having a problem with reloading 9mm where the bullet is not tight enough in the case after being seated. If I run 10 rounds out of the press I can probably push 1 or 2 bullets down into the case with my thumb. I do not reload a lot of 9mm but this has not been a problem in the past. I searched and most similar posts seem to recommend more crimp. I have increased crimp tonight and still no better (even crimped until i have made a dent in the bullet but they are still not tight). It seems to me it is either a tired batch of brass (I dont always keep track of the number of reloads) or the sizing die is not doing its job correctly. The dies are Hornady carbide and the bullets are precision delta. I gave up for the night and will try again tomorrow but does anyone have suggestions of what to check? Thanks!
