Here's what I am wondering: I normally load my .223 with 26 grains of W748 and prime with CCI450 primers. This is for a standard 55gr. FMJ. With this recipe I can get roughly 260 per pound of 748. So has anyone here done a 15% load reduction with W748? The reason I am looking to reduce is to get more bang for my buck out of a pound of powder for plinking rounds. At 15% reduction I can get around an extra 50 per pound. I have two concerns though. The first is too little powder equalling dangerous detonation, and two insufficient gas to cycle the rifle. Any thoughts?
