Whew, you may have just saved a life.
The 10mm auto (which was actually the original modern .40 caliber auto pistol round, developed by Jeff Cooper and friends) used a large pistol primer. Original .454 Casull cases meant for the Freedom Arms revolvers used small rifle primers. The .38-40 (which is really a .40 caliber, in spite of the ".38") uses large pistol primers, even though it was originally a rifle round, but is mainly used in revolvers today (not "pistols", but "revolvers" but, alas, there are no "revolver" primers). One can specify large or small primer pockets when ordering .22 or 6mm PPC cases. And on and on... we could go on all day like this. Generally speaking, the only hard and fast "rule" when discussing metalic cartridges is that there are exceptions to every "rule".
