I setup the Mec for AA's with # 9s and loaded them and was very happy and after trying the cheddite I loaded about 50 and I did not even have to change the settings. I loaded a couple AA's tonight that I shot testing a Mossberg 410 and reloaded them on the same setting again. The little Mec 600 Jr is really impressing me for 410. I have no idea of clubs around here to join to reduce my cost on hulls and shot, and right now I do not know if I will like skeet enough to worry about it. Work keeps me plenty busy in the spring and early summer so I do not know if I will have time to shoot. I appreciate the information though as I will be buying more cheddites if I continue to shoot 410. I did get my cheddites from BPI and got my 12 gauge stuff from Grafs. Thanks Guys
