I'm getting into 20 gauge reloading next. I'll just be loading 7/8 oz target loads of 7.5's. I have 700x and Winchester 572 now for 12 and 28 gauge respectively. and I have lots of Federal 209a primers. Looks like 700x is is not the best 20 gauge powder, but 572 looks promising. When I look on Hodgdon's website for for 572, they only list Remington "RXP, Premier and STS" for the Remington hulls (which I prefer, but I'm not yet married to them). Now, for 12 gauge, Gun Clubs load the same as STS hulls. Is this not the case with 20 gauge?
