The other load that would do that was W630P. Don't remember the load. I put 3,500 rounds of heavy .44 mag. rounds through my new M29 4" in 3 1/2 months, maybe closer to 4 months. At the time, I was
dating a young university gal. who could keep 5 in a row in the black at 25 yards, shooting 2-handed of course. All I loaded then, was 21gr. 2400 and that 275 SWC. That's about all her wrists could take, but I've never seen such a deliberate shooter before while being injured. Never flinched a shot. Married her and now this June, is our 50th anniversary. While we were engaged, she bought a .36 Seneca - 'bout 1976 when she bought it, just before our marriage.
Wore out that gun, ditched it and bought the one I shoot now as a 6". Shot it for a bit, then shortened and re-registered it in 4" persuasion. Gotta like that "punch you in the chest" instead of climbing into the sky. I found the longer barrels climbed like that. I could always shoot the 4" more rapidly and accurately, even on the range at the sheep on the bank at 300 meters.(rested, of course)
The only loads I've made up that actually hurt, were some 21gr. W296 with 300gr. Truncated coned hard cast. With a round butt-grip, those stung. Same day I shot a 5 1/2" .500 Mag. with factory 350's and it was a peach to shoot in comparison to that .44 load. The guy with the .500 offered me a few shots as "it kicks less than that .44". He was right. that was fun. I could only fit 2 fingers on the round butt grips. The little one curled under the grip. Nasty with those 300 gr. loads.
