Loading for a 44 mag pistol and a 44 mag rifle.

H110 has a very small range between starting load (23.0 Gr) and a max load (24.0 Gr.) Most other powders have a much larger spread between min and max loads, for rifle loads easily 5 grains or more.

What makes H 110 so finicky??
 
It's a double base propellant and somewhat more difficult to ignite if not near max load or if the primer's not hot enough (often requiring magnum or rifle primers). Works great for full power loads, but not recommended for reduced power.
 
It's the same stuff as 296, if that helps at all with data. I use it in 357 Magnum, and as others have suggested, it likes to be at max. I started with the max load, then I pushed it further, and it responded well. I'm not recommending to go out of book, but for those with some experience it's worth a try. I specifically sought out older data, as the listed max loads were much more generous before everyone lawyered up.

The Hornady manuals list charges from 19.4gr. to 25gr. for 110/296 with 240gr. bullets ( rifle and handgun ).
 
I'll just add that 23.5grs H110 is my charge weight for 240gr JHP in a Marlin 1894 rifle, does 1650 fps from 16.5" barrel
 
Apparently H110 is unstable when not loaded to max/near max so that’s why all the load data is only a grain or so different from start and max loads
It’s a great powder for high power 44 mag, 357, and others but if you want a milder round you need to use a different powder
 
Again, because this powder should probably only be loaded at or very, very, very, near max. Some of the older manuals made it more clear, like this...

The manual you scanned is Lee's, which had NO jacketed bullet loads developed, or tested, by them. It simply regurgitated data published by the powder manufacturers themselves. If you look at a Winchester load manual, you will note that they only give 1 load for that bullet in that cartridge.

Yes, it's Lee's, but I'm not sure why you care that it's regurgitated. A lot of data is "regurgitated". 1) The jacketed load listed is proven, even todbartell in this very thread provided his personal experience. 2) The point of the post being that the OP should only really care about max loads with H110/296 and not worry so much about charge windows.

Some people see the books/data as gospel, others, like myself, see them as guidelines for what's possible.

Y'all be safe now...
 
I use H110 for both subsonic and supersonic loads in the 350 legend. At least for that cartridge there is at least 3 grains of difference between the starting and max loads for both those applications. That said, even a mid range load for the supers is spicy.
 
I pointed it out because none of the loads in that book were tested by Lee. They simply copied what Winchester published. Quite different than actually-tested loads worked up by the publishers of manuals, like Sierra, Hornady, Nosler, Lyman, Barnes, Berger, Swift, Woodleigh.
does not matter they were tested by a manufacture so all is good all data is regurgitated manuals are guide lines only that's why you work up loads to specific firearm
if you want regurgitated just look on the internet how many posts on this topic is repeated
