I have some IMR-4198 that I want to use up and I want to make some mid-range to 3/4 power 44 Mag loads for my snub nosed 44 Mag revolver. Does anyone know how 4198 takes to being downloaded?
Filling the case from 75% to 95% load density of 4198 behind a 240gr cast bullet is what I have in mind and trying it out.

I was suprised to find this in the an old 1998 IMR powder guide. IMR 4198-25.5 gr compressed -Rem.240gr sp-.430" dia.-Rem 2 1/2 primer- 1515 fps - 22" rifle bbl.. 1.610" COL-Rem. Case. 26,400 CUP chamber pressure. Not a good powder choice, as you know. But they do list slower burn rates of IMR powders @ very low pressure. IMR 4831 is the slowest, 720 fps. :eek: CAUTION: The following post includes loading data not currently published for this cartridge. USE AT YOUR OWN RISK.

If you use it in a short barreled pistol it is probably going to blow a lot of unburned powder from the barrel which will make it a very dirty shooting session.

I'd go for 100% load density.
Let us know how it works. I have some H4198 that I've thought about trying in a 44.
I think 243winxb meant 26,400 CUP. 4198 should work ok at that pressure.

I really like the performance of 4198 in a few calibers in my Contender but man, I do not like trying to load it, trying to cut those sticks. I have to help the rotor cut the sticks with my other hand nearly every throw. I have screwed up the necks on more than a few pieces of tapered brass because of trying to use 4198. After you get it loaded it's a wonderful powder but I'm not buying any more.

23gr of 4198 is as much as I feel comfortable trying to get in a case. 22gr is slightly compressed and at 23gr you can feel the resistance on the press handle. I'm loading a 240gr SWC bevel base bullet.
I took a few out just a while ago and torched them off and it seems to be just about the power level I'm looking for in a snub.

Like loading 4350 in a 30/30. If you want max speed in a 44 Mag, use Alliant'e 300MP.

Curious about accuracy.
And velocity, if you have a chronograph.
And if you used a magnum primer.

I tried it with 240 xtp bullets; but shot them from a rifle. decent accuracy(@ 3" at 100 yds.) As mentioned, not good powder for snub revolver
