Thanks for the good info Frank.
I think I'm going to stick with the 16" barrel then. Saves me a $200 tax stamp and I'm looking for the ability to load supersonic rounds anyway for hunting.
I have a pretty good supply of .223 brass to make into .300 brass so even if it cracks after 10-15 firings it won't be a big deal. Annealing sounds like alot of work.
I guess the only question then is location of the gas tube. Supersonics seems that they would cycle the action no problem with either length. I guess the only argument for a pistol length gas tube would be reliable cycling of subsonics.
So which would be easier or better for the internals then?.......pistol length and "closing up the gas hole" with an adjustable gas block to prevent "too much" gas with the SUPER-sonics OR a carbine length and "opening up the gas hole" with an adjustable to allow for "too little gas" with the SUB-sonics?
