With recommended "trim to" length brass, the two crimp grooves should result in COAL of:
1.610" and 1.690".
1.610" is the listed max loaded length of the .44Mag. That length should work in all guns.
1.690" may not. IF it fits in your revolver's cylinder, fine. Marlins are notorious for not liking overlong loads, and too long will jam the rifle trying to feed from the tube to the chamber. Even 336s.
If your Ruger .44 carbine is the semi auto one, cast bullets (any size) are a bad idea. Lead and bullet lube can clog the gas system. Stick with jacketed bullets in those rifles. Additionally, the early Ruger carbines had a reputation for not shooting anything but 240gr bullets accurately.
W231 is a powder for "popper" loads in .44Mag. which is fine, since that's what you're looking for. HOWEVER, pay CAREFUL attention to the powder charge, with the amount of 231 used, a double charge will fit in the .44 case (and with some room to spare, so its not obvious, and you need to LOOK carefully at every case charged. A double charge of 231 WILL damage (and usually explode) the gun!!!
