Trust me, unless you're a glutton for punishment, you DON'T want to buy a .444. That was the first rifle I ever bought, and it pretty much ruined rifles for me for the next 4 decades. Reloading on an old RCBS JR press was no picnic, either .
I've wanted a 444 Marlin since I was 13 year old kid reading Mack Bolan pulp novels.
A year or two ago, I started thinking about it, and reading. What you described regarding punishment is what I was reading. It seemed the 450 Marlin was the same round, more or less, and available in rifles that brutalized your shoulder a bit less, and I started thinking the 450 was a better option, BUT then I lost the romantic angle with the 444, and the desire subsided completely. I think about it now and then, but realistically, it's not going to happen.
Will be putting together a much lighter ladder, or rather, ladders, as I think I'll also try one with 231.
You're in luck. David Milam, the brains and guts behind Cajun Gunworks, the builder of the custom 97B-E, is a bullseye guy, and his pet load for his 97 is not only a 200gr SWC with 231, it's a Missouri Bullet Company 200gr SWC with 231:
Missouri Bullet 200 H&G SWC -- .240" OAL -- .469 crimp -- 4.8gr W231 By the way, that 1.240 OAL is what I arrived at with the HG68 200gr SWC for my 97, as well. Try it if you aren't already there.
Crimp is important with lead bullets and taper crimped pistol cartridges. And by important, I mean it's important not to overdo it. A lot of people make the mistake of overcrimping, thinking that it will help secure the bullet. The opposite is true. Crimping past flush (also known as a
good crimp
) reduces neck tension below the case mouth, and it is neck tension that holds bullet in place. You don't ever want to crimp past flush. I'd try the .469 that David lists above. That's what I use myself. Forgive me if you know all that already, but I think you said you came from rifle, and lots of rifle guys (and revolver guys) are used to roll crimping into cannelures, and they come to straight wall pistol cases thinking crimping past flush is a good thing for those calibers, as well, but it ain't.
