M700,
My 1894 will shoot 2" to 2-1/2" at 100 yards with my loads using a skinner receiver peep and a 0.050" aperture. The rifle may do better than that, but like PJ says, I am the weak link. It has shot well with the H'dy 240 gr HP/XTP, the Rem 240 gr JSP component bullet, and an NEI #252 SWC-GC hard cast heat treated bullet. It didn't do so well with an LBT 300 gr LFN-GC hard cast heat treated bullet. So far, W-296, H-110, Li'l Gun have all worked pretty well. My most accurate loadings are with 240 grain bullets running 1,740 to 1,750 (chrono'd) using those powders. Loads with 2400 didn't get me up in that velocity range, nor were they as accurate as the other powders.
Overall, it seems like my 1894 has a penchant for the 240 gr bullets as opposed to the heavier bullets, and powders a bit on the slow side of the spectrum for the .44 Mag. Playing with different primers didn't make much of a difference, so long as I kept the velocity in that 1750 fps neighborhood.
I haven't played with bullets lighter than 240 grains -- yet, but have been toying with that idea. Seems like the 240 gr bullets have worked so well that I don't have much motivation to change.
