Alliant 2400 in 45-60

[y2k]

I`ve got a load that works good in my 45-60. 290gr Lyman cast bullet with 23gr of Alliant 2400. Seems to shoot alright and not much signs of high pressure, but I have very little idea of velocity?
Anyone have a similar load in in 45-70 maybe?

Have lever action 2400 data for a 292 grain cast bullet in my old Lyman book. 24.0(1290 fps) to 33.0(1623 fps).
Loaddata.com shows 1089 to 1300 fps with a 300 grain JHP.
