10 & 16 G with Green Dot

Pete I think you are right. What's your charge when you load 1 1/4 oz, looking for the same velocity ?

I have been shooting 27 grains of Green Dot in the Federal hull with 1 1/4 ounce of lead. My decision to load 27 grains was based on a published Alliant load in the 3.5" length hull, it has a M/V of 1265 fps with 29 grains of Green Dot. My educated guess is the 27 grains is moving it along at 1175 to 1200 fps. Looking at published reloading data it seems there is a very close correlation to the % increase and decrease in velocity with % increase and decrease the amount of powder, not perfect but close.

PS. Pressure on the 29 grain load in the 3.5" hull was 8800 psi so 27 will be even lower, my guess probably around 8000 psi.

I need to figure out how much Unique , Green Dot and Universal Clays to use in the 10 gauge with the SP-10 wad a 16 gauge 1/8" filler and 1 1/4 ounces of shot and keep the velocity around 1100 FPS . May also try for the same thing with Blue Dot and Herco .
