The original .30-30 load used a 170 grain bullet and 30 grains (the second 30) of a propellant ballistically much like IMR 3031. That is still a good load. If you want to reload .30-30 using spitzer bullets, you can. But if so, is safest to load one round in the chamber and one in the magazine. The old story about igniting cartridges with spitzer bullets in a tubular magazine under recoil is mainly a myth. Many tests have shown it does not happen.
