What is the caliber stamped on the barrel? The 99 was chambered in 25-35 Winchester early on but the action was strong enough to handle much heavier rounds in the 308 family. The 25-20 is a smaller cartridge than the 25-35 and would be dangerous. It might be possible to form cases from 30-30 brass but I am not positive. Midway carries 25-35 but it is pricey. You would have to get enough to reload and roll your own.
