    Short of patterning, what is the consensus when the reloader reduces his shot weight from 1-oz to 7/8oz, assuming he keeps the muzzle velocity and shot size the same; should he tighten his choke?

    The general consensus is that you'll have a lighter fringe, with about a good, reasonable center density that was not quite as hot as the heavier load.

    NOTHING is going to swim through your center 20".

    If you go up a constriction, you'll have a smaller, tighter diameter (including a reasonably deadly fringe).

    NOTHING is going to swim through your center 22".

    This pretty-well holds for velocities 1180±, but 24gm or 7/8oz can get flukey dense or flukey spread above and below speed.

    Alllllthatsaid ... YMMV and your barrel will tell you what it likes.

    Chichay, The patterns I have shot using 7/8 oz were ugly, with holes. I would go to the next size smaller choke from what you used for 1oz , or Extra full

    If you don't pattern, you are just guessing. My current barrels handle 24g loads wonderfully well, even the .019" choke. My last gun didn't. Patterns were like Jerry P's. So what does that tell you about your gun? A half hour spent patterning will answer your question.

    Tightning the choke probably will just make the pattern worse (more holes). See http://www.shootingbunker.com/OpenItUp.html for an example. Schroll to the bottom of the page.

    As Goatskin says, less shot less fringe. If you center the pattern every time, the target will break. Most of us need those fringe pellets a couple of times out of each 100; we want all the fringe we can get.
