I can’t imagine what the projectile would do to the bore on the way out. Melted copper everywhere.

Na they’re only loaded with trail boss .22/50 blackout

Then there’s this one designed by P.O. Ackley to try and set a world record.

.22 TUBA II rimmed collector cartridge.The parent case is a .44 Magnum shortened and necked down to .22 calibre.


There was (probably still is) a rifle on used guns in 22-45 tuba, the rimless version of this.
It’s crazy the stuff people decide to build, but hey who am I to judge.

That first one would be a good little round, I’d like a 221 fireball but that would also fit the bill nicely.

I know what you mean.
I have had a soft spot for a 17 Fireball and it is on the wish list… one day…

I’ve had 17 Rem, 222, 223s over the years. Loved the 17, being able to see the bullet impact in the scope. I would love to replicate that with a 221 Fireball someday.
