45-70 Gov't Load recommendations

[tomcat13]

I've been reloading 45-70 Gov't for quite a while (Cast w/Lube & Jacketed). Shoot em thru Ruger #3, Browning B78 & Remington Rolling Block. I've decided to try Powder Coated Cast Boolits. Just bought some 500 G from ACME (NOT the place Wile-E-Coyote gets his stuff). Looking for suggestions on Powders & Quantities. Don't wanna use Black Powder. Like to stay around 1200 FPS. Thanks for any & all Advice!

You can use the same load data that you would for cast and lubed. Start there.

Thanks again for info provided. Now the concern loading these 500g "Logs" is Seating Depth. They are Flat Nose & in order to get the OAL down to 2.540-2.550, I have to seat them Real Deep. Bottom of the Boolit goes in, all the way Past the "ring" on Winchester Brass. Wondering about Internal Pressures when I set these things off. Any thoughts?

Looking to run them thru Ruger #3, Browning B-78(Both r Falling Block) & possibly Remington Rolling Block (Pedersoli Replica)

Can't speak to the first 2 guns, but I had a Pedersoli rolling block that shot the 500 grain bullets well. I took an empty case and pushed a boolit into the mouth, then chambered the cartridge. That gave me the seating depth. 42-43 grains of 3031 shot very well out of that gun.
