I just got this 9mm Lee factory crimp die. It does not seem to be a taper crimp, but does put a very narrow crimp on the mouth, and it still checks OK in my Wilson pistol max case gage. Is that normal? Typically, I would add the bullet diameter to twice the case wall thickness at the mouth, then adjust a taper crimp die down until it was about 0.0015" less in diameter there.
Also, the bullets seem to 'stick' in the crimp collet and make a slight 'bang' noise when withdrawn. I tried polishing the inside dia. there, and used a little Imperial sizing wax. Still bangs.
Do I have a defective die? Finished rounds look OK.
The instructions mention, "The crimp is correct for the cartridge. Revolver cartridges are crimped with a beautiful , uniform roll crimp found on factory ammunition. The crimp is fully adjustable". etc. Ambiguous statement. NO mention is made about a factory taper crimp, and the die is sold as a 9MM Luger die.
Is it meant to be used in a 9MM Luger revolver only, like a S&W 986?
Question for Lee 9mm factory crimp die users.
