I have a double auto with identical 30" barrels, I got the idea of putting one of the old adjustable chokes on the end (the older ones). I scored an adjustomatic and was wondering if anybody has any experience with them, est instructions for installation or use.
What do you think the best barrel length is for the adjustable choke, I was thinking 28" or maybe 27" and the choke is 1" - I have the other 30" full for the DA too.
