Posting this just for the amusement of the board.

I bought a 44mag Henry X model last year, 17.4 barrel. I wanted it just for the potential of more "bush" hunting, shooting a deer under 100y. I've got a red dot on it. We've all heard about what the best powders for 44mag, but what about for top velos from a rifle? I used Speer 220gr FPJ pills, COAL of 1.605, virgin Winchester brass. The test was between 300MP, H110, and VV N110. I scoured the internet and reloading data trying to find max loads for this bullet, but there was very little I could find. On some, I ended up just going for an in between of a 200 and 240gr bullet. I did find one loading for the N110.

So, for the 300MP I used 27gr, H110 26gr, and N110 24gr. For those that don't use them, 300MP and H110 are spherical and N110 is extruded. So, for that loading of N110, it was actually JUST starting to be compressed to where the COAL actually changed to 1.610. I assume with some shaking and seating of the powder, along with some crunching, you could probably get it to 24.5 gr. Someone may jump on and say I could have used 27 for the H110 as well, but this was the best I could find. Even so I don't think adding another gr would have made it match either of the other two.

The results of 5 shot averages: 300MP 1820 fps, H110 1748 fps, and N110 1864 fps.

Of worth noting, the N110 was also the most accurate and had the least deviation. Now, this is hitting a paper target at 50y with a red dot, so using scope I could have been more accurate. Still, the groupings looked a good bit better with the N110.

For me, the N110 is the clear winner for this rifle. The pressure should be lower, and it was the most accurate. I'll eventually do a test with some other bullets, I just wanted to see what kind of velo I could actually get with the lighter bullet. I've got plenty of 240gr XTPs to use, along with a box of 225gr FTX and 265 gr FTX. I've seen reviews that the 265gr is an excellent dear round, while the 225 fragments.
 
Good info.

I have tried N110 in short barrels (5” and 6”) but never my rifle. I may have to try it now.

I’m not surprised that H110 was slower, but the N110 results surprised me. What primers did you use?
 
Magnum primers would have helped with the H110. Lil Gun might have got you a little more velocity but all you loaded are plenty fast.

Win LP primers are for magnum or standard applications.

WLP is listed as "for both standard and magnum". It's what I've used in my 44mag loads since I started reloading. Don't know if another brand of LPPmag would do anything different. Always worth more "testing". :)

I don’t think they work as well as Federal Magnum. Can’t say about CCI. I would only use CCI as a last resort in any handgun load. It’s not going to vary that much in any case. It always seems like Federal Magnum works the best with H110 for me, but I use Federal Magnum in all my handgun loads small or large size and also light Target to Full bore magnum.
 
The largest deviation was with the H110, so I wonder if a different primer would make a difference. If nothing else, just the deviation and have them a little more accurate. The N110 was within 10fps of every shot. The H110 was up to 50! (Stating my chrono was reading well.)

I haven't tried Federal primers in handgun loads. Good to know.

FWIW, some powders work better with non-magnum primers, even in magnum applications. 2400 is one such powder. Alliant also lists regular primers for their 300MP data.
