Load Data Advice - 44 Magnum - Rifle and Pistol

[TheBuckle]

I'm kind of new to this and I'm looking for some advice as to find load data and I can't find any that fits what I have.

I need a deer hunting load for three different firearms within 50 yds.:
S&W 629 6" (44 Mag)
Rugero Vaquero 4" (44 Mag) (Original vaquero not new)
Marlin 1894 lever action rifle 20" (44 Mag)

Due to shortages online and in stores here is what I have to work with:
- New Winchester 44 Mag brass
- Hornady 240 gr. XTP bullets (44 Mag)
- Winchester and CCI Large Pistol Primers in Magnum (That's all I could find)
- Accurate 4100 Powder (Closest I could find to WIN 296 and H110)

Based on what I could find on (https://www.accuratepowder.com/products/handgun/?view=8&product=4100) their load data for a handgun is MIN = 20.3 gr. - MAX = 22.5.

My questions are:
The load data from accuratepowder.com doesn't use magnum primers and it is only based on a handgun.
1. Should I expect to have issues with the magnum primers in this combination?
2. Should the lever action rifle operate properly with this combination.

Trying to be safe and accurate (within the constraints of what I have available.)

Thanks in advance for suggestions and advice.

The rated chamber pressure is exactly the same but generally you will get more velosity with the carbine. Using jacketed bullets should prevent some of the fit issues that people find shooting lead in the carbine. Never used that powder.... mag primers are not an issue if loads are worked up with them

should you decide at any time in the future to go hard cast, which to me seems a perfectly sound choice for revolvers and lever guns, Oregon Trail Bullets loading guide has load data for both rifle and std and ruger pistol loads, so that you can make sound decisions about your loads without having to spend half a day researching it if you are sharing rounds between handgun and rifle.

Using Accurate's data, you should have no problem with that load in anything you are loading it for, although I'll suggest you are going to get some muzzle blast in that 4" Vaquero.

I also load .41 for 3 revolvers and an 1894. The slower powders (like your 4100...) will make use of all that barrel length of the 1894, for sure; I pick up significant velocity between mine and the handguns. Two of my revolvers are 4", and I typically don't load them with the slow powders like H110, although it performs well enough; about the slowest I go in 4" is 2400, but usually Unique.

Hope you don't mind a link to a very similar thread I create almost two years ago. I was in a very similar situation working up a 44 Mag load for use in both a revolver and carbine. I was using the exact same bullet, hopefully the thread is somewhat helpful.

I think your components will work fine and I don't think the magnum primers will give you any issues, work the load up as normal.

That’s the true magic of having a rifle and revolver capable of shooting the exact same loads.

Once you can find other powder and bullets you’ll be experimenting with different load combos all the time.

Stay safe.

1. Should I expect to have issues with the magnum primers in this combination?

No, WLP or a Mag primer will work with your spherical powder .

Accurate 4100 powder does NOT require magnum primers, but they will work fine. The WLPs are not as hot as the CCI 350s, so I would start with them. I've always had great accuracy using WLPs with 4100. You also do not need to be concerned about minimum charges with 4100, like you do with H110/296. I would start at about 18 gr and work up in half grain increments to a max of 22 gr, concentrating on accuracy. The milder loads will still be more than deadly enough at 50-75 yards, and will be more pleasant to shoot. But if your most accurate load is the max load, then all the better.

I have been reliably and repeatedly informed in another thread that one should not rely on information posted to internet forums. If it's not printed in the Hornady manual it is not reliable.

Its very possible that a mag primer will generate greater pressure. Therefore when working up, I would stop a bit short of Accurate's max powder charge.

I agree with your comment about internet posts. However, the 10th ed. Hornady manual doesn't list this powder/bullet combo but the powder manufacturer does list it as a working combo. So I do plan to start the load at the minimum and work up. Some things are just not in the books yet.

You found primers? You’re very fortunate. I’d like to know from where.

Used the same load (H110/240JHP) in a 6" 629 and a 16" '94 Marlin; inside of 100 yards, the load is a hammer on deer. Took 3 with the revolver and a bunch with the carbine; they were either DRT or only went a few steps.
The carbine picks up 200'sec over the revo.

^^^This. Your Winchester LP primers are designated for both "magnum " or "standard" loads anyway. Even with Mag primers, the small amount of difference is moot if you stay within published loads and work your way up. Trying to make ammo for three different guns(two different platforms) will be the easiest and most likely produce the best accuracy in all three, using jacketed bullets. Especially since .44 carbines tend to have a different bore diameter than .44 revolvers. Regardless, you load for the cartridge, not the platform. IOWs, pressure specs and load recipes are the exact same for revolvers and rifles in .44 mag.
