I'm traveling right now so I don't have access to my loading logs or I could help you out with the details a bit better. As it is, I'm something like 6,000 miles from home, so here is my "off the top of my head" answer.

I've had great success with 3031 and the Hornady 300 grain bullet in the Marlin 1895. In a friend's (with micro-groove rifling) that combo shoots a true MOA for 5 shot groups and is very consistant over a chronograph. I used the Hornady manual from the 1980s to work up the load.

Start low and just work up gradually until either recoil or pressure signs signal you to back off. I know that in my friends light carbine, recoil was the deciding factor for us and due to good accuracy and adaquate velocity we stopped a couple of grains below the max load in the manual.
