H335 is spherical powder that will measure about as good. It has a burn rate close to 3031 and that is all I ever used in a 30-30.Years ago 335 was sold as a surplus powder same as the old 4831. It came in a plastic lined paper bag. I loaded a lot of it in the 30-30, but also in a 30-06, .308, 7.65 Argentine Instructions that came with it said to use 3031 loading data. As mentioned BlC-2 will work too.
With today's short supplies, you might have to use what you can find. Work on finding primers first. , Bullets are a lot easier to find, and you can compromise on the powder type
