So from what I gather this is custom lathe turned brass with considerable advantages. There is a $250 wildcat set up fee minimum of 100 pieces for a wildcat order or 50 pieces for regular non wildcat order. There is an additional $50 for a head stamp with a custom head stamp of your choosing which is dirt cheap! It is made from hammer forged brass/copper in diameters of 5/8” 7/8” or 1 1/4” It is tested to 65,000 K psi and they will even do a benchrest level quality. Apparently people have used the brass dozens of times without fail. It comes lathe turned with fully formed taper, shoulders and necks. Cost is expensive, but small runs! About $5 a pop for normal stuff to $10 a pop for cases like the mighty T-Rex or say a 12 Gauge or 4 bore capable of 65k PSI. A great option for hard to find stuff or wildcatting on a small scale. This is pretty cool stuff!

If this be the Wine of Madness......come fill my cup!
