I am new here, and I am 16. I started around the age of 10, and I have a couple of unknown cartridges:
From left to right: 8mm Mauser, Unknown, 30 Carbine, Unknown, 44 S&W Russian
They are both wildcats based off of 30-06 military cases. OAL of the 1st cartridge is 56mm, and the 2nd is 28.3mm. They are both 30 caliber.
