A friend of mine bought a Parker choked tight mod and tight full. We shot factory loads at a pattern board and confirmed the chokes were tighter than he wanted. We loaded some hulls the old way using card and fiber wads and the chokes opened up to a loose mod and tight mod. We loaded up some spreader loads and achieved a variety of usable patterns. Before I would ream out the chokes, I would attempt to get the desired patterns by reloading using card and fiber and spreader loads.
+2.... So simple.........but some people around here just can't figure that one out...I guess it's just easier to butcher the barrels and turn the vintage gun into a "one use only" gun, sad indeed........
There are also other reloading techniques to accomplish those same open patterns with factory full choked vintage guns should you shoot at close ranges, but still want an unbutchered vintage gun to shoot at long range for other species.........then you can carry short range ammo in the left pocket, long range ammo in the right pocket, depending on the topography and your hunting style, i.e. dog or no dog, Eastern or Western or in between.......
