6UM-40 Brass

[treillw]

Would anyone happen to have two pieces of 6UM-40 brass that I could buy? Want them to make some dummy rounds.

UM is out of stock of brass and hasn't responded to my emails about getting a couple pieces.

Thanks!

Thread 'Brass Swap Thread'

Jan 26, 2026

In the same spirit as the bullet swap thread, this is meant for small quantity swaps/trades/sales etc. I'm thinking primarily for mock ups, wildcat testing, dummy cartridges, etc. Not a classifieds for components, but a place to exchange small quantities for testing.

Right now I'm looking for:

• 6 Dasher (for feeding test, bad primer pockets are fine)
• 6 GT (Same as above)

I have available:

• 300 WSM (Nosler/Norma/Rem)
• 300 WM (Hornady)
• 243 Improved (Winchester)
• 243 Winchester (Winchester)
• 308
• 25-06
• 270 Win
• 30-06
• 22-250 (Rem, Win, Federal)
• 223...
