Primer pocket uniforming question

[Classicvette63]

Small pistol primer pockets are different than small rifle primer pockets, thus requiring a different tool to uniform them.? Is this correct? I guess the same would be true for large pistol vs large rifle cases?

I bought a small primer pocket uniformer for use on the .218 Bee, but if I could use it on the .357 mag cases I would. Lymans instructions were a little lacking in clarifying things. Thanks
