I've recently started using a 20 ga semi-auto for skeet, and will start reloading for it. The only powder I could find for 20 ga is Longshot, and bought a pound of it. I have Win 209 primers, CB-1078 wads, and with primarily Gun Club hulls, and a few Winchester Universal hulls. I'll be loading on a MEC 600 jr. that a friend is lending me until I find a used one locally.
For 7/8 oz., the recipes for Gun Clubs on the Hodgdon website call for 17.9 grains, 9,900 PSI, and 1250 fps. If the recipes are the same for AA and Universal hulls, the numbers are 18.6 grains, 10,600 PSI, 1250 fps.
My question is with regards to bushings. I use a 600 Jr in 12 ga, and the bushings I already have are 29~33. Does anyone else use Longshot on a 600 Jr., and if so, what bushing(s) do you use? I guess what I want to know is whether I need to run out and get a smaller one.
