Lee #2 has some info for the 25-20:
85 grain lead bullet is listed with 6 to 7 grains H4227 (1317 fps, unknown test gun, 20KPSI)
The jacketed loads run up to 25 KPSI.
Hodgdon may be the originator of this data as they list the same.
Glen Fryxell has an excellent article on the 25-20.
Read it here:
Cast bullets in the .25-20 Winchester
He says:
"In terms of powder selection, there is load data out there for the .25-20 for powders ranging from about Red Dot on the fast side,
up to Acc. Arms 2015 BR on the slow side, with 4227 appearing to be just about optimum (and 4227 has been a historical favorite in the .25-20)."
"For reference, the Lyman Handbook of Cast Bullets (published in 1958) reports loading data for the 85 grain gas-checked 257312,
it lists a maximum load of 10.7 grains of 4227 producing 1750 fps."
He got best results with a plain based 85 with 8 grains 4227.
He goes to 10 grains with a gas checked 86.
His conclusion:
"8.0 grains of 4227 was consistently accurate with all of the 85-86 grains cast bullets (PB and GC), and generally delivered 1650-1700 fps with them. The plain-based 257283 with this powder charge (1680 fps) is now my preferred small game load for this rifle. I don’t want any more velocity, and no GC is needed. Simple and easy. This combination is capable of shooting into just over an inch at 50 yards."
