You must be one he!! of a good shot if the barrels are 33 and 39. The old standard was full=030. With all the new crap in choke tubes full is 035. Either way you have full and extra full. Not conducive to skeet shooting. Maybe handicap trap past the 25 yard line would be better suited for those chokes. Good luck. Oh, looks a real nice gun if you're not one to worry about it being correct. The top lever is sitting too far to the left for the checkering to be that nice. Man, did someone pick a mighty fine looking piece of wood. The recoil pad looks nice. From the picture it looks like maybe the stock was replaced years ago and was cleaned up and recheckered because the wood looks dark near the receiver, like it's oil soaked. With the changes already done to the gun I wouldn't be afraid to get the chokes opened up a bit if you ever wanted to. Looks like you have a real nice shooter.
