Choke tube?

[findergameandfish]

I have a Beretta A-390ST wondering what aftermarket choke tube to purchase? I have been looking at the pattern Master wondering if any one has info on it, or use's it in there Beretta?

i use a pattern master and the thing shoots great. never patturned it out on paper, but i love the effects on geese, and occasionally used it for pheasants... if ya use it on pheasant though, make sure to let them fly a bit farther that a typical shot, otherwise your going to be eating quite a few bb's. i wouldn't consider anything else though for bustin geese, outperforms any of the others that i've used

Choke tube for what? Need more specifics. What species, typical circumstances, etc...

How do you know if you haven't patterned it?
