What calibre are these?

[Spawn-Inc]

found these in the bottom of my range bag, wondering what they are. 22lr for size comparison.

Im sure ill be wrong but ill take a guess and say some kind of whisper round "300 whisper" or 300 blackout.

Not sure if those rounds are rimmed though. Also weird looking bullet. Green?

I'll bite.
.256 Win?

Definitely not 300Whisper or Blackout.

11.3 x 52mm Dutch Beaumont?

No stamping on the case?

For sure not a .256 Win. Mag

ok ok, they are 38spl cases necked down with a lee .329 sizing die which just happens to have great neck tension to hold a .312 bullet

i was going to fire them in my ruger, but they are to long, so i may pull the bullet and flip them around.

Nip or hack saw off the nose, bingo, wad cutters that fit.

I wish I had the money or tooling to make a proper chamber for them, they look and feel awesome. Sorta like a mini 303 brit.

Shoot them in what gun/chamber? A 357/38? The bullet would rattle down the barrel.

 

[crashcollins]

Ya! What the heck do you have that you can shoot those in?

 

[Spawn-Inc]

Ya I know, but I was board. I filled the cases with trailboss so not sure how well they will fire form back to 38spl but I will try the next range trip.

The reloading forum seems really slow as of late so I figured I would get some interesting/silly threads going.

Thats a first.
