I am needing a Krieger or Bartlien 6.5 caliber, 8.5 or 8 twist barrel for a new F-class rifle. I am building this to shoot the F-class nationals in September so I don't have time to order one from the company. Does anyone know of anyone that has these in stock. I am really wanting the full contour 1.250 @ the muzzle. All help is appreciated. Thanks, Dean-o
