Afternoon everyone.

I was recently given a few hundred 240 grain wax lubed, hard cast round nose slugs to load in my little Henry H015-44 rifle.

Now I’ve never loaded for my .44 before, nor have I any experience with lead bullets. What’s more, my Speer manual shows no data for that bullet material/weight, and the powder I have on hand (IMR4227).

So I was wondering, has anyone here seen any published data with these components for the .44 mag?
 
Speer is a company that makes jacketed bullets so that's most of what they will publish. Nearly every other manual by powder or equipment companies will have lots of loads.
Or a quick google search will produce hundreds of thousands of results.
 
Re Outsider: The person who gave me the bullets purchased them from the Bullet Barn in Spirit River Alberta.

Re Third Rail: When I first tried using the Hodgdon site as reference, all I saw was a max load for lead but no starting load. Perhaps I read the information wrong?

I did try this first but I couldn’t find any published data, just plenty of pet loads.

Admittedly I could have dug a little harder, but opted to ask here instead.
 
Speer manual # 11 has data for 240gr in .44 mag jacketed and tmj starting load; 22gr imr 4227 with a magnum primer 1213fps, max load; 24gr imr 4227 with magnum primer 1312fps. I would begin with the 22gr load, lead bullets move down the barrel with less friction than jacketed bullets = less pressure.
Hard cast bullets are made with a lead alloy that makes harder bullets especially when water quenched this allows the bullet to be fired at higher velocities without leading the barrel(bullet to bore fit is the best assurance against leading!) also hard cast bullets do not expand as much on impact as soft lead bullets.
