Merry Christmas!
I have been loading the 44Mag for carbines for a while now. Indiana has those goofy rifle cartridge rules and I wanted to take advantage of them while using a standard cartridge, well, at least in the beginning!
I have shot a bunch of bullets out of several different rifle types with varied results.
When starting out, I wanted the lever gun to shoot less than 1 1/2" @ 100 yards. I was able to achieve that with either the Remington JSP or the Hornady XTP, both in 240gr. I was able to achieve right at 1800fps from my Marlin 1894 CS (?). I cast and wanted to get a lead bullet to give the same performance as the XTP and after many frustrating hours, What I learned was this: The Marlin has an oversize bore, and, when I loaded the lead bullets through my Square Deal B, the carbide crimping die was resizing the case/bullet combination causing the bullet to be too small and accuracy was seriously lacking. Here is a result of running them on my RL450B after purchasing a second standard crimping/seating die and removing the seating plug:

I never could get my M77/44 to shoot anywhere near this good but, it was still hunting accurate with groups up to 2" @ 100. That was with the XTP too.
Then, I thought I would get an Encore and give that platform a whirl. It was the most accurate with the XTP and I really liked it. I am going to make it into a 445SuperMag though and see how fast I can run that 240gr our of it!
Here is the group I shot with it. Kind of in a hurry though. I shot the first one at the left of the group and used it as my target and shot the subsequent group. By far the most accurate of all of the platforms I tried.
And here is the results of a friend using the Remington JSP out of his Marlin 1894, from a deer that he shot in the boiler room @ 140 yards. This was recovered on the offside, just under the skin.
I have pictures of the results of the lead bullet as used on a groundhog @ 75 yards and the carcass of the deer mentioned above.
Let me know if you want to see them.....

They are kind of graphic.
