Thanks for the input. I will get it on the pattern board just to confirm what it is doing. I have shot a couple rounds of trap with it and it breaks 35 to 40 yard birds well with 1oz loads so I would think the remaining choke is doing something.
The barrels were cut well, square, no missing solder. The gun itself is an older restock and reblue, both very nicely done, Gun is tight and on face.
I think I will just leave it as it is.
