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.

49ereric. Yes I suspect I have hit the speed threshold but with my limited experience with cast it’s worth the ask. I unfortunately cannot use my chronograph at the indoor range but I’m guessing I’m running about 1700fps.

Here is the bullet.

At the most accurate load I’m still getting a bit of soot and the crimp doesn’t fully expand out. I may just try a hotter primer or .2 grain more to see if it gets me there.

Good hard bullet you have so no issue there I believe.
Find a .431 and or .432 bullet. Sample packs of both if possible.
Chrono isn’t needed just is the barrel leading and accuracy.

I've shot cast lead bullets in many of my rifles, including my .375 RUM, for many years. I cast them with wheel weights or harder lead and are bullets that use gas checks.

The cast bullets that I use in my .375 RUM weigh 280 gr and with IMR 4198 powder and a dacron filler will shoot under 2" 3-shot groups at 100 yds that hit 5-6" below my full power 300 gr TSX loads.

Couple points with your quest, as I load for a few 44's and a 444 Marlin rifle:

• You've discovered reduced charges of H110 is a no-go. This is a "max load or nothing" powder and is my go-to for such things. I'd never use it with regular lead bullets for fear of driving them too fast and leading the crap out of the barrel.
• I know you tried faster powders but were uncomfortable because of case fill, but you might be selling yourself short. Attention to detail is a part of reloading, and if you're not trying quicker pistol powders (Unique, AA5, W231, etc.) you're not having as much fun as you should. I settled on lighter charges of W231 for scenarios like yours and have been very happy. 240's at either 750 or 950fps are super fun out of handguns and total powder puffs out of a rifle. Adjust accordingly for 200's.
• If you're sticking with Heavy Pistol, I'd stay with your 17.5gr load if it's accurate. No sense in maxing out the practice/goofing around load. Make it comfortable to shoot and save the heavy stuff for hunting.

To editorialize a bit - you might want to try plated bullets instead of cast. I am migrating away from lead (not hard cast, though) to plated for range time. So much less BS to deal with and dramatically cleaner all around. They only cost a few pennies more a piece, which I'm happy to pay.
