Gil,
Go to Alliant's on-line guide & do a search...
http://www.alliantpowder.com/default.aspx You will find that 1200 fps 6000psi loads are easily doable using Extra-Lite powder in the Fed paper cases w/the CB 6100 wad. The Federal paper cases smell correct when fired, too. Backing off slightly should put you in the ballpark for what you are seeking. Anyway, the nice thing about their 'reloaders guide' is that it lets you specify what components you might like to search. Should you not find them specifically listed, they are also very customer oriented & will guide you toward what you need, if you contact them. They are 'shooters' as well as ballisticians, it's a happy combination. Same may be said for Hogdon's. As a rule, not everything tested is published & I have been told that the tendency is to generally NOT publish loads below 7000 psi for fear that some OP may have a less than desireable experience trying to use said loads for a 'rusty' ill cared for semi-auto .. and none of them need the grief sure to be associated w/that sort of experience. It's similar to why the ammunition makers load 'hot' light weight promotional ammo .. they want a clunky rusty semi-auto to function with it.
You may also wish to check w/Ballistic Products as they have a lot of good test data & components for same. I have had very good experiences with their VP05 wads in light charge weight 12 ga. loads. Prices are most attractive on case lots of 6K; they are 'bulk' packed.
Lastly, I have never understood the concern over powder residue. I'd be willing to bet that most any posting on this site clean their guns after each use, correctly. I'll easily concede that some powders burn leaving less residue that others, but do not make that a criteria for choosing a powder, far from it.
Hope something of use to you above.
Kind regards, tw
