If you have a tight or undersized Shell Holder, you have two options. If you have a small hand grinder, you can try and modify the Shell Holder to fit, removing any interference. Or you can return the Shell Holder to us with a sample case and we can modify the Shell Holder for you.
We make our Shell Holders -.000/+.002. Case manufacturers make the cases +.000/-.008.
