Levi391, 4756 is a powder that is designed for heavy payloads, for 1 1/4 oz. or heavier. It is a progressive burning powder that develops low chamber pressures. 1 1/8 oz. doesn't provide enough 'back pressure" or "setback" to enable the powder to develop enough chamber pressure to perform efficiently. 4756 just isn't designed for standard 1 1/8 oz. trap loads. I would suggest you locate a dedicated game shooter and negotiate a trade for a powder that better suits your purpose. Break 'em all! Tom Ruble
levi391, as you've been told 4756 is not really intended for 1.125 loads. I have one that is a lab tested load for 1.125 running out at 1550 fps but really don't want to give it out. Where do you live? If somewhere in the vacinity of me I would be happy to trade you a better powder for your needs.
