257 Blackjack

.25 Creedmoor?

I am getting 3160 with Retumbo in a custom reamer to allow me to seat them out appropriately. Shot a 4 inch group at 900 yards with mine. I also have a 25 SST. I shot a cow elk at 665 yards this year. DRT, didn’t take a step. I have been very impressed with accuracy and bullet performance in the 131 BJ’s.

I really would like to do a 25 Sherman. Would love to see ADG do headstamped brass in 25 Sherman (or 6.5).

.25 Creedmoor?

No. The .257 Blackjack. It's a short stumpy SA magnum cartridge designed by the guys at Blackjack. That's what this thread is about

Soooo…

Is there a write up somewhere about how to make .257 blackjack brass? I couldn’t find anything. But if there’s anything on social media I won’t be finding it

Only this. But I wouldnt recommend it until there is an option for it. For now the Saum would be a little better way to go.

If you're gonna run in a true short action, the 25sst is a good case, 71 gr powder, in between saum/prc. 1.95 case length, longer neck and 30° shoulder, just almost all taper removed.
