So, I bought a box of the 225 grain JSP which is rated at 860 FPS from a 7 1/2" barrelled revolver. By comparison with my Lyman 48th Edition loading manual, I think that I can expect about 1070 FPS from my Marlin Cowboy 20" barrel. That's pretty slow for a 1:38" twist, I know, but I wanted a baseline to compare to my handloads. I haven't owned the gun long. Has anybody shot this ammo from their Marlin 1894, and if so, what kind of results did you get with regards to accuracy? In particular, has anyone targeted this ammo at 100 yards? How about other brands of standard velocity ammo in the 225 to 255 grain range? Do groups open up a lot? I'll know when I get out to shoot, but I'm interested in the experiences of others.
