PS ,,,I finally got my pics. downloaded,,,the ctg on the left is the fire-formed finished case that is ~.030" longer than std. to clean up all of the old existing chamber,,,the one on the right is new unfired case,,,sorry about the fuzzy pic quality,,,,the last pic with the white back ground shows the diff between the 22 Nosler and .223 rem.,,as you can see the Nosler has aprox. the same volume as a 220 Russian,,,,this case would make a great 20 cal or 6mm ctg as well !!!!!

I am going to presume that the necks on this brass is really thick, cuz i wonder about the .255-.256 dia neck on the chamber.

I have 224 rounds down my 22" woa 12 twist tube. Its is rifle length gas. It does swipe a little, sometimes worse than others but since it is primarily a night time coyote calling gun I can live with it given the 3550 velocity with 55s in an AR. I have around 9 or so loadings on some of my brass and still going. I currenty have it tore down to spot face the receiver and to bed the barrel extension chasing some flyers. 10% of my rounds are getting out near an inch and a little beyond at 100.
I have one of the first of their first batch of barrels but I know they have since lengthened their gas system aprox. 2 inches longer than rifle length on their longer barrels. I spoke with an individual who has one and there was still occasional swiping with factory 55 nosler rounds.
