    I have a couple of older SuperX and 1100 guns with .040 constriction, considered Xtra full these days. They shoot great patterns. Always wondered why they choked the guns that tight? Card wads? And why aren't guns choked that tight now? Barrels on the SupX are .736 - .735 The Rem 1100's are +/- .730. Most new guns are .736+/-, but chokes aren't .040.

    Imorovements on ammunition over the past 20 years have allowed for less constriction in the choke to provide the same or better patterns.

    You young whippersnappers don't know what we went through with paper shells and fiber wads. The newer plastic shells and wads have really improved performance of the load at extended range. Powder has gotten better as well.

    ...but they still shoot tighter. Maybe tighter than they need to - some say so - but tighter nonetheless.

    In general only, of course. My tightest gun was an 870 with 0.034 choke, but mostly 0.040 puts the most pellets in 30 inches at 40 yards.

    Andrew Jones got the same results as well.

    Neil- If you want to play with a choke tighter than your 0.034 Rem. I could send one of my older M-12 guns to you. Winchester believed that 0.04 was full and 0.035 was IM.

    The SuperX and older 1100 barrels are great shooters!

    Maybe the answer to our Handicap issues is right in front of our eyes. Maybe all we have to do is restrict the max. choke constriction to .030 or less. Then we'll be playing the game the way it was designed.

    Let's put our resident patterning expert on that one!!

    Bores on newer 1100's and 1187's are nominally .727", with .036" being the accepted full choke.

    Older bores are nominally .730", with .040" being the accepted full choke.

    The difference in bore size is .003", and the difference in choke constriction is .004".

    So, there really isn't much difference when you compare the barrels and chokes mathmatically (only .001", which is insignificant and is less than the standard deviation of the bore size anyway).
