I'm just starting to load for my 44mag desert eagle. I've been using 32gn of h110 for the 50ae barrel and cci magnum large pistol primer. I'm going to load h110 in the 44mag cases too, but I'm wondering if its ok to use the same magnum primer for the 44 mag load? All my manuals show standard LP primers. Should I reduce the load or just load as usual? Thanks.
In all of my Magnum cartridges I load them with Magnum Primers. This includes any Maximums, Super What Evers, and the whole family of big thunder boomers.
The Magnum Primers do increase the case pressure, the problem that I have seen with H110, which I do load a lot of, is that the loads amount is very narrow, so you can not back off your load 10% to try out the combination. My lyman 49th Edition shows the 44 Mag loads using H110 and 296 (same powder) are loaded with Magnum Primers. I don't have any experience with the 44 Auto Mag, so I can't say if loading that cartridge with H110 and Mag Primers is the proper combination.
The gun is extremely strong and needs very stout loads to work the action. There isnt much of a variation in the charge weight because h110 works best when loaded stout, I'm told. Its not meant to be down loaded I guess. Thank you for the info.
I reload 44mag for a Marlin lever action. Different than your Desert Eagle, yes, but everything I've read indicates you need the magnum LP primers when using H110 or 296 (same powder, as Jerry said), AND a nice, tight crimp to keep the pressure high enough to ensure proper burn. You're using CCI LP magnums, so I would load down about 5 or 10% from maximum, and then go back up from there (though Jerry may be right about how much % you can actually back off). I use Winchester LP primers and, though they're not "listed" as such, they are a magnum primer. In fact, without going out to check a tray, I believe they're marked as "for use when standard and magnum primers are called for" or some such statement.
By the way, I'm using 23.4gr of H110 and WLP for my 240gr XTP bulleted rifle loads.
Hodgdon recommends you only back off 3% with H110. I wouldn't worry about using Mag primers, ball powders need Mag powders because the flame front doesn't flow through as easily as with stick or flake powders.
I load for my 44mag DE also. The weapon is quite strong and I load some pretty hot loads in the 265-300gr area. My hog killer is the 300gr with a generous dose of H110 and CCI 350's.
It has been my experience that when switching from non-mag to mag primers a drop in 1gr of powder will usually make up for the difference. Same for the rifle calibers for all powders. This is not done,of course for the very fast powders(like Bullseye). IOW,max load of powder and you want to switch to mag primers,simply drop the powder charge by 1 full grain.
As stated....this has worked for me.... YMMV. -----pruhdlr
you dont' have to use a mag primers I had 2 444 marlins I used 44 mags in it to save powder I used std primers and got good results. you should have no problum. i've been reloading for 40 years.
I suspect you guys may be right about the magnum primer, but I could've swore we had a discussion last year about unburnt powder and wimp loads in the .44 mag cartridge, and the answer (I thought) was magnum primers and a tight crimp (especially using W296/H110). Maybe I'm getting that mixed up with another caliber. Or maybe it wasn;t that you needed a "mag primer", but needed one like WLR that serves dual purpose as standard and magnum. Could that have been it?
I use winchester large pistol for normal and magnum load primers. I did a comparison with cci 350's using 24.5gr h110 under a 240gr bullet. They performed the same and the winchester had a slight edge in keeping a tighter average velocity.
