BPCR Loads for Original Trapdoor Carbine???

[Lawful Larry]

I have some black powder cartridge reloads that I use in my Trapdoor rifle, but they seemed a little too stout for my carbine. I am using a 405 gr. RNFP bullet and 65 grs. of BP. I can remember reading that this was a little too heavy for the short carbines and the government down sized the powder charge. I can't remember what the charge was, can someone help me?

If I down size the charge, I will have to use some form of filler I suppose. I know some of my CAS parts use Cream of wheat, but a friend said there is something much better. If so where can I get some of this stuff?

The early carbine load was 55 grs of 1f powder under the 405 gr bullet (well it actually weighs 385...) they later left that when the infantry round went to the 500 gr bullet and used the 70 gr load for everybody.
You may not need any filler under your 405 gr bullet if you use 1f powder, but if you do cork wads would be your best bet to fill the space. Same with 2f, but 2f may foul heavier than the 1f.
The old books such as Sharps and Remington's catalog cautioned against using "to fine" of a powder as fouling would go up.

I used a lube wad .3 thick to help with my wife's load of 50 grains of 2f and a 320 grain bullet.

Thanks for the response guys.  Right now I am using 2f Goex and a fiber wad for my rifle loads.  Don't have any cork wads so will go with the cream of wheat and 55 grs. for the carbine.
