Ok you are technically correct. Gotta say though that I have heard WCO's here refer to 2B (not just Allegheny County) as an SRA due to the extended season. They were one and the same before the new WMU's.
In any case, I stand corrected.

What I should have said at first is that we are likely to see a shotguns only reg first appear in the remainder of 2B and 5C and 5D before it happens elsewhere.
