Would be hard choice between my M1 Garand and SC03A3. Ammuntion of any type is heavy, ammunition loaded into magazines is even heavier, either of these can be carried with lots of enbloc clips, or even more in 5rd stripper clips. 30-06 is a do it all cartridge, and the 03A3 probably takes a lead against the M1 Garand since its not as ammunition specific. Not that I'd want to be shooting lots of 180gr to 220gr loads out of her, but she can.
