Thank you Kutter. Your idea worked. Shot it today at sporting clays very well and then patterned it. Pattern was perfectly centered which is what I like. Easy to tell since the pattern is less than ten inches at 16 yards. I think the chokes get opened a bit when I have some time over the winter. It is a beautiful model 37 that I have not shot in ten years. Lots of fun!

So many guns, so little time!
