We all know or should by now that earlier guns are over bored ( I just take that for granted) that's the ball park part of it. I shoot A LOT of test patterns . I found that for the most part these guns shoot tighter that what the chokes say they should. I have shot 1 oz loads of old Remington 4's from the late 40's to early 50's with out the plastic wads and got 83 % patterns out of my .035 (full) choked 12 ga.. parker would not worry about constriction, they would shoot until they got what pattern they were looking for I would think ??

Joe from Mo; Don't drive yourself crazy worrying about chokes.

Pete and Scott do it the right way and are diligent pattern testers and their success in the field and on the clays course show it. I pattern every gun I own as soon as I get it and am more concerned with the point of impact (POI). It does'nt matter what choke you have if it's not going where you want it to.

My advice falls in line with Joe G. Shoot all those guns with whatever load is comfortable for you and shoot lots and lots of clays. A comfortable load allows you to shoot more, period.

Remember- Chokes are measured in inches; Misses are measured in feet.
Keep shooting until you are not chipping targets on a regular basis and are getting nice even breaks. Then you will know that target is in the center of your pattern no matter what choke constriction you have. You will be surprised at how well you can shoot a tightly choked gun.
