For me at least, it will be whatever barrel is available. I am seeing good and bad in factory and aftermarket barrels.
That's the problem with the Interweb. It's difficult to know if there are any problems inherent in the various manufacturer's work. I should take my own advice. It's about Lee Precision, but is appropriate here. If any of the equipment made was substandard, the company would stop producing it or go out of business.
