Is anyone using or has used RL19 in the 45/70. I use to load AA3100 in my 45/70 but it is no longer available. I do have some RL19 that is just slightly faster burning. Was wondering if it would work? Using 330gr and 430 gr bullets.

Wednesday day, bump. Waiting for a reply to email sent to Powder Co.
I can't help you with the RL19 question, but I happen to have an unopened pound of AA3100. Do you mind sharing your 45/70 data for that powder? I haven't had much luck finding data for it.
325gr gas check and 405gr powder coated is what I load right now.

While I have not tried that powder, Ken Waters found H4831 worked tolerably well (somewhat similar in burn speed) as long as a few conditions were met. These were a caseful of powder to the base of the bullet and heavy rather than lightweight bullets. No 325s, in other words, and he found it better with weights well north of 400 grains, like 450 plus.
This is not a loading recommendation for you, but that is what he did. Burning of the powder was not clean but with heavy weight bullets he found it acceptable and the unburned granules of powder caused him no real trouble.
This is what one would expect with powders not ideal for the application. This is the situation you find yourself in with RL 19.
I've used H4350 and it does well but I shot at least 515 gr bullets.
OK My old AA manual says 54 to 60 gr with either bullet.
19,000 pressure for the max loads
54 gr 1300 fps and 60 gr 1500 fps for the lighter 300 to 330 gr bullet
54 gr 1250 fps and 60 gr 1422 fps for the 405 grain bullet
54 gr 1314 fps and 60 gr 1513 fps for the 500 gr bullet 25,700 pressure
All max loads are compressed loads
Hope this helped
I was using 54gr with a lyman 457193 that was 430gr and getting 1200 fps from my Marlin Guide gun
Heard back from Accurate powder, they were of no help. Said go to Reloader #7. So much for their support.

Yeah, not sure about RL19, but would suspect it will be a compressed and a brutal load if you put enough powder in there to burn completely. I myself use RL7 and it works quite well across a broad range of velocities. I have seen data for Varget, but it is faster than RL19.
