I recently received an order of 2K 357sig once fired cases for reloading. About 70% are Speer, they have flash holes so small that my RCBS universal de-capping die will not work. Some people say to order a Lee decapper. One person said he uses a drill to enlarge the hole, so it matches other head stamps like Winchester.
My question is how different flash holes might affect my reloads? Different burn rate, pressure, MV? Especially in a mixed head stamp environment.
