What year K-22 are most likely to have tight chambers

[JH1951]

Back to the original question.... "...but which years were the chambers most likely to be a little tight and need a bit of reaming?"
Many comments tend to implicate worn reamers at the factory, and I tend to agree.
Now which year had more tight chambers?
I will venture a guess - 1948.
I base that simply on production numbers, and 1948 seems to be "the year of the K-22" with production somewhere around 54K if memory serves me well. (Please correct me if I am wrong. The older I get, the better I get at being wrong.)
I have a 1947 shipped piece and it is a work of art and function; bricks of ammo through it with hardly any turn line and never a sticky chamber.

I can't find any correlation to year. I have had to ream chambers on a 1st year K22 Outdoorsman, a 17-2 a 17-4, a 617-6, a Mod 34-1, a 63-1, and a 1926 Heavy Frame Target. Some needed a lot of chamber reaming, some just taking a few high spots, but enough to cause "sticking".
