    What powder? Sounds like you were using something that is a little on the 'slow' side.

    move back when you chronograph them. At least 6' between the muzzle and the first screen. Your 7/8 oz loads are definitely going faster than the 1oz loads with that load of Clays.

    I used to load 7/8 oz but used 18 grains of clays. I loved them, but I don't reload anymore. No time.

    Just try 18.2 or so and you should get 1240 with STS or WW. Just a pressure situation.

    I'm with the side of more powder for more and reliable pressure and consistent burn. I'd recommend at least 17 gr. of Clays, an appropriate wad, Win. or similar primer and a true 7/8 oz of shot for 16 yards, 1st shot of doubles, skeet, and close sporties....Bob Dodd

    poppy5, we need to know what you mean by slower. You have to consider the spread as well as the average (mean). How much different were the means and how many shells were tested? If the extreme spreads (either of them) were much over 30 or 40 fps the speed averages don't mean much.
