44 magnum is a pistol cartridge. Takes large pistol primers. I have handguns and rifles in 44 Remington magnum. Large rifle primers would sit high possibly being set off by closing the action or if used in a semi causes a slam fire. I have federal sr here that are labeled as use for rifle and high velocity pistol. I have used sr in place of sp with good results.Is the 44 Mag cartridge a rifle cartridge?
