What is causing this? Prob one out of 25 I load. Never noticed any deformed hull or anything like that . It’s coming from the main crimp die. Thanks for any advice

What length (or range) do you find for a 'good' Gun Club hull?This problem drove me to drink and I never thought to thank Remington. I have had many of the same results with Gun Clubs on my Hornady 366, and it came to the length of the Gun Clubs varied quite a bit. I used a go no go cardboard length gauge made to sort out the ones that were too long or too short. You will be surprised at how many fail. As a side note to this, I had been loading Gun Clubs of an older vintage without incident. Somewhere along the way I think quality control of the length went out the window.
2 3/4" on the money. Many measure 2 11/16" and they tend to leave a small hole in the crimp. Those that measure 2 13/16" and up tend to the fold over crimp the OP was experiencing. That's a pretty wide swing in length and enough to loose consistency.What length (or range) do you find for a 'good' Gun Club hull?
