new load for 44 mag

[mosseater]

That seems to be the max loading for 200gr that I've read. Have you chronoed them, and what kind of groups are you seeing?

The Hodgdon 1999 basic reloading manual (the free one) lists 28.5 gr of H110 (same powder as W296) with a 200 gr Nosler JHP (COL. 1.600). The limiting factor with this load is probably how much powder can fit in the case. With other bullet types or shorter seating lengths you might have to use less powder. It is difficult to compress H110 a lot so just use light compression.

They also list a 240 gr Nos JHP with 24.0 gr H110 (same length).

Please double check these numbers for yourself before you load. I am sure you can find the manual online somewhere.

In an older Micro-groove and a 2009 1894SS, I get 2'' groups. Bigger once the barrel heats.
Velocity was over 2000, but not quite the 2100 fps that Hodgden lists.

Here's the link to Nosler's .44 cal 240 gr. bullet:

https://load-data.nosler.com/load-da...ington-magnum/

Their most accurate load appears to be 22.8 gr. H110 (103% load density), vel 1661 fps.

Their max load for H110 appears to be 23.8 gr. H110 (108% load density), vel 1724 fps.

A few random thoughts.........

H110 / W296 are the EXACT same powders and it has always been that way. When I see one had different reloading data or one is more accurate I just smile a little.

You can compress H110 / W296 a little.

The most accurate load is firearm specific so you need to determine this yourself.

There is no load listed for H110 / W296 and a 200 grain bullet. This confirms my suspicions and is what I mentioned earlier. H110 / W296 rules when pushing a heavy for caliber bullet and 200 gr for a .44 is too light. If you look at Noslers 240 and 300 grain loads you will see no other powder comes close.

Save the 200 grain bullets for plinking and get some 300 grainers. You will sprout one chest hair for every round you shoot .

I actually found three loadings out of my older books for 200 gr JHP, and they're all very similar starting at 27 gr 296/110 and going to 28.5 gr max. If I can get my powder measure to work I can start loading some test rounds. I can get a new charge bar for 40 bucks delivered, or a whole measure with both charge bars for 110. Older style charge bar is too warn to scale. Newer bar works but is too small to get enough charge in the case. Gonna sleep on it.

Don’t know if I’m stating the obvious, but magnum primers are mandatory with 296/H110. Even with that, however, I’ve had multiple rounds squib when using 296, so I’m sworn off it. Unfortunately, I haven’t run across anything that promises the same velocity. 4227 gets close, but I often find unburnt powder in the barrel and action.

I’m pretty sure Elmer based his 44 mag loads on 2400 and I’ve found it to do very well. HTH
