250A with 20 " barrel seem fairly common. When you do see an A with a 22" barrel, it's usually a 243, occasionally a 308. I I would say the 250A with a 22" barrel is not rare, but fairly uncommon.

I think late in the production run of the A's when they went to 22" standard barrels, they were probably selling twenty 243s for every one 250.
