MarkOue,
I have two model 23's one is a Heavy duck. From all I have read the model 21 is the strongest action ever built. I belive and I am NOT Qouting this that in the book Model 21 its states a crazy amount of proof rounds they put thru the 21. It was stopped if I remember correctly because it became to expensive to continue. it had already surpassed all other American made doubles of the time. Sorry i can not give you the exact. Its been a while since I have read the book. I also do not have it here in Iraq to look up. However I highly recommend every model 21 fan to buy it and read it. Great book loaded with info and great pictures too. what gave away I am a Devil Dog????? My lack of spelling and grammer?????? I could have been an officer. LOL
