Home Forums Reloading Bullet Casting What weight bullet could I cast for both 45-70 and 45-90?

I am looking for a good choice bullet for two rifles.

My good friend has a Browning High Wall in 45-90 and I hope to get a Marlin 1895 in 45-70. He often tries to hunt Nilgai near El Paso with his but he hasn't won that lottery yet. By the time I get good and ready, California will have banned hunting with lead so it's milk jugs for me until I can afford an out of state hunt.
I am still a novice caster but I enjoy it. I could really use some of your experience and wisdom. Of course if one bullet won't work, what are your favorites for these calibers?

Thanks in advance.
