Primer pocket uniforming question

[Ol` Joe]

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

There is a difference in height between the sm pistol & small rifle primers, you should use the proper uniformer for these cases. The Lg rifle and pistol I believe are the same but would not swear to it.
I use Sinclair Lg rifle and Sm rifle tools on my Rifle cases but can`t see any need for doing pistol cases. The small gain in uniformity won`t help my poor shooting with a handgun.
