Thanks for the help suggestions. I got my JP adjustible gas block last night, and will try to install it this week. Any idea how much I can open up the gas port? Do I just use a standard drill to do this, or will it leave a burr in the barrel?

I worked the bolt quite a bit, but it still looks like it needs more gas flow. The bolt unlocks with the 125 corbon load, but not enough to eject the empty or pick up a live round.

Very cool cartridge, though, and well worth the work getting the gun set p. I also have a Contender barrel on order, as I have learned that the round is Illinois deer legal (one of the very few bottle neck pistol calibers that fit their requirements: case length less than 1.4 inches, minimum .30 caliber, and make at least 500 ftlbs of energy at the muzzle from a factory published load.)

thanks
