Ignoring the issue of shooting one rifle in both the Pistol Cartridge and Rifle Cartridge categories, what's the preferred caliber and rifle for just Pistol Cartridge. The usual criteria apply: accuracy, minimal recoil, sufficient knock-down power (rams), reliability, ergonomics, etc.
I'm inclined towards the Marlin 1894FG because of the pistol grip and checkering and past success with Marlin's, but I've read that there's magazine feeding problems.
