In my 92 Win. with an LBT 90gr plain base, using my black powder lube, I use 9 grs of 5744 for 1425 ish fps. This load also works well with the Lyman 65gr. gc. 

With the 65gr. gc. I also use 3.4grs. of AA#2 for 1150ish fps.

At one point 30 odd years ago I had several pounds of IMR 4320. A case full to the base of the bullet shot well with the LBT 90gr. and gave black powder velocity. It shot well enough that I won many NRA Lever Action Silhouett matches.

In those days I was poor as a church mouse and couldn't afford to test endless varieties. So I used one primer, ran a few powder charges with what ever powder I had on hand. Thats why I used 4320, it's all I had. I used CCI sml. rfl. because it was also all I had. I always guessed that I just got lucky with that load combination.

I once bought a 25-20 Savage 23 just so I could swipe the magazine for my 32-20 model 23. Did yours come with a magazine? 

Well......... not getting too much load data, so have started with 7.2gr of H110 and a 75gr GC bullet loaded to 1.60" length. Gotta start somewhere.

Gave my Savage Model 23 to my brother. I'm guessing he still has it as he almost never sells a gun. And, seem to remember that it had two (2) magazines.

I am sitting on the fence. 6.5 4227 or 4.8 Unique.  85 gr PB cast. Side by side test tomorrow 40 shot match conditions on painted cardboard, actual critter size & distance. Half one load half the other.   

Bench one thing how the rifle is handled less than case full Offhand often another. Trajectory factor as well. Go too,
fast difficult zeroing chickens center hold. Sight bottoms out. 

Be interested in your H110 load. 4227 6.5 unburned powder in the bore which seems to have no effect on performance.  Heavier charge may be too fast for my plain base bullet & shoots over the top of chickens. Your GC bullet probably the best solution.
