    Additionally, when I shoot my single barreled pump gun (20ga Rem 870) at early season teal and decoying ducks, I use the IC choke.

    Pattern numbers from a 20-gauge Remington 870 with 26" Rem-choke barrel and Carlson's flush chokes (patterns average of five, 30" post-shot scribed circle, yardage taped muzzle to target, and in-shell pellet count average of five).

    20 GA 3" REMINGTON NITRO-STEEL MAGNUM LOAD
    1 oz #4 steel (191 pellets) @ 1330 fps
    30 YARDS – IC / pattern 156 (82%)
    40 YARDS – IC / pattern 138 (72%)

    Good luck!

    Joe, I appreciate the work you've done with patterning; you've sunk a lot of time and money into that project. :tu
    One thing you might consider adding is a disclaimer on your results; pattern density (percentages) are but one aspect of effective patterns. The other, and arguably more important component of patterns, is their distribution (pattern evenness).
    I can have a 100% pattern at 40 yards that is all but unusable because all the pellets are lumped in one small area. That would be an extreme and unlikely case, but some degree of this characteristic is present in all patterns and....to me at least....determines if a pattern is a good one or not.
    Just a suggestion.
    And, again, thank you for all your efforts. It's very helpful to many on here.

    Thanks JH my patterns with (7 loads) the mod at 30 were avg 80% and IM at 40 avg 75%.

    Every load was shot with the factory IC and with the exception of the Kent 3s no patterns were acceptable.

    I don’t know if its the shot string with a 20 gauge or what, but since I’ve switched to using a full choke in my SX3, it doesn’t leave the gun. It just straight up kills better and I’ve never blown up a bird like a close decoy shot with a 12 gauge can. A shooter is swinging the gun, so a 3 dimensional pattern will look a lot different than what a stationary pattern does. In regard to payload, I’m taking the heavier payload almost every time. The only exception would be my preference for 7/8 oz of #6 steel for dove hunting.

    Tuleman -- Thanks for the kind words and I agree that percentages and pellet counts are only part of the picture, although pretty important baseline info. I only hope that my pattern numbers with my gun/chokes will encourage hunters to put their gun/choke/load combo on paper, at the distance they intend to use their combo, to make sure it will be effective.

    Buster -- I also prefer the the 1-ounce load when using #4 steel or larger.
    Here are my pattern numbers for the Remington load that I normally use.

    Pattern numbers from a 20-gauge Browning Citori with 28" Invector-plus barrels and Briley flush chokes (patterns average of five, 30" post-shot scribed circle, yardage taped muzzle to target, and in-shell pellet count average of five).

    20 GA 3" REMINGTON NITRO-STEEL MAGNUM LOAD
    1 oz #4 steel (191 pellets) @ 1330 fps
    30 YARDS – CYL / pattern 104 (56%)
    30 YARDS – SK / pattern 134 (70%)
    30 YARDS – IC / pattern 164 (86%)
    30 YARDS – M / pattern 179 (94%)
    40 YARDS – M / pattern 139 (73%)
    40 YARDS – IM / pattern 147 (77%)
    40 YARDS – LF / pattern 145 (76%)
    40 YARDS – F / pattern 149 (78%)
    40 YARDS – XF / pattern 152 (80%)

    For teal and close decoy shooting, a #6 steel load load works just fine, too. Here are my pattern numbers with a 3/4-ounce #6 steel load.

    Pattern results from a 20-gauge Browning Citori with 28" Invector-plus barrels using Briley flush chokes (patterns average of five, 30" post-shot scribed circle, yardage taped muzzle to target, and in-shell pellet count average of five).

    20 GA 2 3/4" WINCHESTER XPERT STEEL LOAD
    3/4 oz #6 steel (231 pellets) @ 1325 fps
    20 YARDS – CYL / pattern 200 (86%)
    30 YARDS – CYL / pattern 123 (53%)
    30 YARDS – SK / pattern 173 (75%)
    30 YARDS – IC / pattern 181 (78%)
    30 YARDS – M / pattern 204 (88%)
    40 YARDS – IM / pattern 155 (67%)
    40 YARDS – LF / pattern 165 (71%)
    40 YARDS – F / pattern 165 (71%)
    40 YARDS – XF / pattern 178 (77%)

    For dove, I normally use #7 steel loads unless the shooting gets out around the 40 yard mark. Here are some of my pattern numbers with 3/4-ounce #7 steel loads that I've shot a good number of dove with.

    Pattern results from a 20-gauge Browning Citori with 28" Invector-plus barrels using Briley flush chokes (patterns average of five, 30" post-shot scribed circle, yardage taped muzzle to target, and in-shell pellet count average of five).

    20 GA 2 3/4" WINCHESTER XPERT STEEL LOAD
    3/4 oz #7 steel (327 pellets) @ 1325 fps
    20 YARDS – CYL / pattern 251 (77%)
    30 YARDS – CYL / pattern 143 (44%)
    30 YARDS – SK / pattern 221 (68%)
    30 YARDS – IC / pattern 242 (74%)
    30 YARDS – M / pattern 272 (83%)
    40 YARDS – IM / pattern 197 (60%)
    40 YARDS – LF / pattern 212 (65%)
    40 YARDS – F / pattern 213 (65%)
    40 YARDS – XF / pattern 222 (68%)

    Good luck!

    Larry -- I hope you find a combo that works for you!

    Speaking of Pattern Densities , they ALL are Gaussian distribution , very few become the same ! That's the reason I shoot 3 shells before walking
    up to the patterning board ! In my mind , the ability to have a shell/load that throws a consistent spread of pellets at the same velocity is paramount
    to a good load ! I can adjust the spread of pellets with choke tube constriction so as long as , each pellets has the potential energy for the distance
    I'll be shooting , I'm satisfied !

    Thanks JH. I'm going to keep patterning, it looks like this one just might need a little more research.

    Same gun/choke w/HW-15 in a 1 ounce load of #7’s.
