40S&W cases as 44mag bullets

Apparently the idea isn't new at all. Interesting and the high speed camera helps.

    I've seen it done with bullets for 22 centerfire bullets using 22 lr cases IIRC..

    I can't figure what might be causing the periodic instability. Maybe inconsistencies the 40 S&W case webs?

    Primer pockets are off center.....

    Those are good guesses. I reload a lot of 40 and I sometimes have to reject some collected range brass because of small non-uniformities. Basically, the brass isn't suppose to be flying so very small non-uniformities aren't that big a deal, unless you're shooting for the best accuracy. This guy is launching them so if the "bullet" isn't symmetrical about the bore axis, it's gonna wobble.
    Another possibility is the actual bullet could be slipping inside the 40 case and not achieving enough spin. Whatever the reason, if you're hard up for 44 bullets but have plenty of 40, well there you go.

    I believe it was RCBS who during WW2 who used .22 brass for bullet swaging, "Rock Chucker Bullet Swaging" got its name.

    Corbins makes (or made.  Have not looked in a while) a hydraulic machine that would stuff lead wire into a .22LR case and swage it to make .223 bullets,

    There's a swaging community out there that does some pretty impressive things.  Fairly high entry cost for the press and the dies. . .however. . .

    You can supposedly turn .223 brass into jackets for a .375 bullet.  I found that to be an intriguing notion...

    I'm thinking the rimmed case makes a much better jacket than a centerfire case. The rimmed one being more consistently concentric.

    I wounder if the metallic fouling is commensurate with guilding metal?
