I've never shot a Snider, so I can only offer vague advice for cast bullets in general.
....the "stopper bullet" came out looking like this... 550 grains, wheel weights, SEC nose profile, .585 diameter, .100 front band length, .420 nose length, 65% meplat, plain base, .090 length of base, 1.0 G to B, & 45* groove angle
I presume you will need to crimp the bullet, to keep the bullet from "walking out" under recoil ? That means you will not be able to adjust the bullet seating depth to fit the throat. That means you need to choose a nose that fits your throat when seated for crimping. It should chamber easily, yet it should not have to jump a long way before it contacts the rifling.
You did not tell us anything about the rifle's throat dimensions, so we can't say whether or not your proposed design is a good fit in the throat.
....the "distance bullet" came out looking like this... 550 grains, wheel weghts, SEC nose profile, .585 diameter, .100 front band length, .420 nose length, 35% meplat, bevel base, .100 length of base, .8 G to B, & 45* groove angle
I never recommend a bevel base. There is no known advantage. The bevel is too small to have any impact on the ballistic coefficient.
In general, I never choose a cast bullet based on ballistic coefficient. That's just not what cast bullets are about, to my way of thinking.
any suggestions to improve either bullet
It has to fit your throat. The throat should be cast-friendly -- do not assume that it will be. Do not assume that your gunsmith knows what a cast-friendly chamber is.
There is some debate about what constitutes the ideal cast bullet throat, but we can agree that long jumps to the rifling, and grossly oversize throat diameters are not ideal.
We can agree that rifling which starts abruptly, without a tapered entrance, is not ideal.
A general rule of thumb is that cast bullet diameter should be 0.002" larger than groove diameter. There are many variables, and the only sure way to determine the ideal diameter is to experiment with several different diameters and see which one shoots best.
You didn't say what velocity you have in mind, but since gas checks are not available for 585, this might be a good excuse to play around with paper patched bullets.
how about lead times
Estimated lead time is always posted on my home page.
Good luck with your project.
