One of the guys in our gun club bought some of the new e3 and loaded 1 1/8 oz #9 with 3 dram equivalent in Remington Premier STS hulls. I shot some of his shells and some of mine loaded with Clays today on the Skeet range and the e3 had a stronger recoil and sharper detonation. Also I could not see any difference in the cleanliness of his gun over mine, but we had only shot about 100 shells each. He likes it, but I think that I will stick to the Clays.
