Sounds like you found a place to start and I wish you the very best as you continue to move forward with your development process.

OK, thanks for the update.  Still have to load some .25-20 SS for my Maynard and Stevens 44 and go try them out!  (And I have both 2400 and 4227 to try ...)

Hornet, are you saying it's not grouping well? I use 6.8 grains of H108 with Lyman 257420 and never any filler with any load in the 25-20 SS.


Is that breach seated or fixed?  Iím fortunate enough to have a nice stash of H108 and if use it at the rate of 6.8 grains per round, it will last a looooonng time!

9.0 grains of 2400 sounds like it might be a little bit hot for weaker actions like my Maynard and Stevens 44?  Did you happen to chronograph your 9.0 grain load to see how fast they are going?

My original Stevens 44 likes 7.8 gr of 4227 with a Western Bullet company hard cast RCBS 25-85 CM bullet.

Yes indeedy.  That's on par with the 1950 fps jacketed-bullet load I used to use in a 44 1/2 for woodchucks back on the farm in Michigan.  Quickload says 30,000 psi.   A Model 44 will shoot loose pretty quickly with that load.  Bolt thrust calculates to about 2100 lbs.; 50% higher than a nominal .32-40 blackpowder load.

Yeah ... I thought that 9.0 grains of 2400 sounded a bit "warm-ish"!

Again, I'll be shooting .25-20ss in a Maynard and a 44 Stevens and I am hoping to find a nice light target load that I can shoot enough in both guns to feed my vintage single shot addiction without battering the rifles.

I'm following this thread with much interest and gleaning load info as it progresses.  Many thanks to everyone for their posts!

My last best loads were for a 96 grain bullet, seated .460 deep. 

6.1 grains AA #9

7.3 grains Ramshot Enforcer  (AA 4100 in a different package)

Both about 1450 fps from a 26" barrel.

Quickload say pressure is about 15,000 psi.

Bolt thrust about 945 lbs.

A Model 44 in good fettle can handle that for quite a long time. 

(Health issues have me on the ropes - not shooting either of my .25-20s anymore.  Both loads could stand further development.)
