CCI's and Remington's are not the same profile. I have had troubles with CCI to the extent I don't like to use them on my revolvers any more. The Remington #10's function flawlessly and I never have to "pinch" a cap...ever.
Both Bass Pro Shops and Cabela's carry the Remington caps. Either find one within driving distance, or do as was suggested and pay the hazmat fee and order a bulk lot. You won't regret it.
