    What is the velocity of: Win AA 1 1/8 #8 with Green Dot 20gr, compared to, 19.5 gr of Green Dot, compared to my old standard (when shooting skeet) of 16.5 Green Dot with 1 1/8 #9. Am I shooting 1235, 1200, more, or less?. Don't have any reloading charts handy. Thanks. John, and I approve this message.

    Without knowing the primers and wads...who knows?

    If YOU know what they are, you can look up the reloading charts on line at Alliant's website.

    Thanks, Capt Morgan. The primers are Win 209 and the wads are Claybusters.

    Even then the numbers are not exact, only approximations.

    Some loads will vary shot to shot by 20FPS up or down, and others can be quite consistent.

    My most consistent Chrony load was a 20 guage with 15.5 of Unique, it stayed inside a 15 FPS envelope, reading about 1215.

    John, you'll not be far wrong if you figure 1200 fps - maybe plus a little - for the 20 grains, a bit less for the 19.5, and both way, way faster than your skeet load.

    With your components; WW209 primer, WAA12 wad, Green Dot powder, AA hull, 1 1/8 oz shot. (Alliant website)

    17.5 gr = 1090

    18 gr = 1145

    19.5 gr = 1200

    21.5 gr = 1250

    I have noticed that velocities published in reloading manuals seem to always end with a 0 or a 5. I am sure the loads in a good manual are safe, but how accurate are the velocity and pressure numbers? If the Alliant plant tested a new load and got the following velocity numbers: 1179,1204,1186, 1190; what velocity would they print in there manual?

    Trap 4 - Do you really thing the manual would list the velocity as 1189.75 ft/sec? I suspect the velocity would be listed as 1200 ft/sec but how accurately would this describe the actual velocity?

    Win 209, CB1118-12, 1 1/8oz West Coast Magnum, 20.2 gr Green Dot lot 724, Win AA new style hull, .060" crimp depth out of my 1100 30" SC1 choke gave 1232 fps on average at about 60 degrees ambient over my chronograph. 19.6 grains went down to 1202 average at about 68 degrees. Changing to the Winchester WAA12 White wad had very little change for velocity. It was statistically insignificant.
