Reloading cast lead for lever guns challenges.

[Blurry1]

I don’t think this has been discussed. I recently bought a 44mag Henry and worked up a nice deer load with h110 and xtp’s. I’ve never messed with cast bullets but decided to work up some plinking loads with some Missouri bullet 200gn coated bullets. I quickly learned that the h110 just pushes them too fast. Lower charges produced sooty cases and increased charges led to rapidly decreasing accuracy. I briefly tried cfe pistol but the low case fill makes me too uncomfortable with the risk of double charges. Take 3: I loaded up some rounds with Shooters World Heavy pistol. Accuracy improved up to 17.5 gn (2in group @ 50yds) and then expanded groups at 18 and 18.5 gn. The question: I have a couple more grains before max. Does anyone find improved accuracy going upward in charge after the groups start to spread with cast or is it a waste of powder as I suspect? Thanks for your thoughts.

To fast? Barrel Leading issue? How hard are the bullets? 12 or 18 BHN? Tell us which bullet you are using not just the grain.
I don’t reload cast lead for rifles yet but at some point but I have the concerns you seem to mention. You might have to slug the barrel to get the size correct.

I remember something about 44 mag rifle having a larger bore than revolvers so a .430 cast bullet might be to small.
A quick search.
The bore in that case is 12 groove, with a .423(+2/-0) bore diameter and .430(+2) groove diameter. I can say that our bore specs are set with the goal of optimizing jacketed bullet performance.
