Don't touch magnum primers, large or small pistol, until you've got a lot of experience in reloading.
Magnum primers release the energy, from a given powder amount, quicker than Regular primers. So if the bullet doesn't get out of the barrel fast enough, it can become really costly... to the pocket and to the hand.
