50-90 Sharps smokeless reloading data

[DRMC]

Anyone know where I could get some reloading data for smokeless powder in a 50-90 Sharps? Looking at AA5744. This is for 10" barrel bfr

Thanks

Sounds like a beast! Was that a custom build from Magnum Research based off the .45-70?
Picture needed!

Might start here with some 45-90 Data

With 520gr bullets 32gr of AA5744

With 405gr bullets 40-40.5gr AA5744

I will get a picture coming ... But it is a custom bfr from grizzly custom revolvers. Thanks for the replies... sorry so long to post my reply...
