Without knowing what powders you have on hand, might I suggest that you try the Hogdgon Reloading Data Center. Lots of .45-70 loads there, from mild to wild.

Ken Waters, in his 1970s groundbreaking article that created the three action strengths for the .45-70, rated the H&R Safari break-open .45-70 as equal to the new 1873 Springfield "trapdoor" .45-70.
This is the "Group 1 - Weak Rifles" category. That said, you can probably safely use loads intended for the 1873 Springfield, but no hotter. The article is in the book, "Handloader's Digest No. 7," which is copyrighted 1975. Though the article is old, the information is still applicable. Waters did not list any 500 gr. jacketed bullet loads in the Group 1 section. I've found numerous references to 500 gr. lead, lubricated bullets suggested for the 1873 Springfield, but no jacketed bullets. You cannot just swap bullets with this data; the lead bullets produce far less friction and resulting pressure than jacketed bullets. You will probably have to contact the powder manufacturers and ask them for a Group 1 load with 500 gr. jacketed bullets. Your rifle sounds ferocious. Shooting 500 gr. bullets from a 14-inch barrel should get you a Christmas card from your local surgeons and orthopedic specialists. But your rifle is hardly the worst "thumper" I've seen. Some years ago, at the Salt Lake City (Utah) gun show, I saw a Ruger No. 1 in .458 Winchester Magnum for sale. The barrel was cut to 16 inches and the stock and forearm thinned. It weighed about 7 pounds. A rifle like that can break or fracture bones! I left it where it was. I never quite got the hang of walking sideways. Have fun with that beast -- and may God have mercy on you!

45-70 handi's are beasts! I own a few and they handle some hot loads with no signs of fatigue

If the OP's frame is a rifle frame of recent manufacture then it is most likely safe with "Marlin level" loads. I own a H&R Shikari in .45-70 purchased new in 1973, and there is no way I'd ever fire 40,000 cup level loads in its cast iron frame. . |

From what I can tell, Reloader7 powder must be made for 45/70 because it seems to me like it shoots everything good and the hotter the better.

More than likely you'll have ADI powders available moreso than any other.Looks like AR2206 would be the best one under that bullet. Muzzle blast is going to be fierce though. Look at the ADI website for the data:
