If well known Company A, lists the same air gauge specs, stress relief, etc., as equally well known Company B, but company A is $100 less expensive, what is the cause for the difference? Customer support is the same. Reading the reviews of each company would lead one to believe the end result is comparable for both company's barrels.
Also, is there a detectable difference in shooting accuracy between SS and CM? If not why would one be preferred over the other?
