Small pistol are not designed to withstand the pressures developed by rifle cartridges, small rifle magnum will work with a reduction of the powder charge.

If you are using them in a semi-auto, they usually take almost a full house load to operate the action so you are stuck with SR or SR-M but if you are using a reduced load in a single shot or bolt action etc., small pistol will work

In bolt guns and single shots it doesn't make much difference. Whatever you work up the load with will probably work fine.

In semi and full autos with floating firing pins, slam fires are a possibility so small rifle at the lease; or if you want to be sure then "military primers".

Here's what CCI has to say about it:
