I asked this question a few years ago. Don't know how far back you have to go to see the post...
After all of the discussion, I decided to go with the Match chambering. Never had/tried the "normal" .22 chambering. I can tell you this much, I don't care what they are like...the .22 Match has been outstanding for me. Super accurate with most ammo (never tried the real cheap stuff). Chamber is a bit tight, but better tight than loose. I would suggest the Match barrel to anyone.
