When Eynsford first was released, I ran a test with 50 rounds thru the 38-40, using 35 grs of 2f, the rcbs 180 bullet lubed with Bullshop Nasa. The gun never tied up, and I used no fouling control, the accuracy was just as good at shot 50 as it was on #1, and he velocity was running at 950 (right where it' supposed to be) from a 4 3/4 inch barrel.
Black Dawg cartridge was loading it in their rounds and the few boxes of rounds sent out for testing,that were shipped before the explosion close operations, drew rave reviews...
Folks that haven't tried it yet, really are missing some of the finest blackpowder available today.
