It’s an AR/Ruger Mini-based magazine, so yes. Cycling is rougher on bolt guns fed from magazines designed for semiautomatic use, vs magazines originally designed for bolt guns. Just something to be aware of for young kids/starter use. The Ruger is likely offered in all the same chambering in the Predator and standard lines, with their rotary magazine of 3-4 rounds.
There can be more muzzle blast in larger cases with smaller bores, and shorter stocks and barrels put this closer to a new shooter….even with the 243. Smaller cases with less powder have something going for them there.
