Hi, I am an active trap shooter and just started getting into reloading. I was just wondering if anyone knows where I could get the specific " recipe" in order to load Winchester Universal shells. The only specifics I know is that the ones I use are Winchester compression formed 2 3/4 " shells, 12 guage, 1 1/8 oz of shot, 7 1/2 shot, 3 dram equivalent (1200fps). Any information on this topic would be greatly appreciated.
