Thanks for the 600 info.
Lightest Alliant published ¾ oz is 15.4 of Unique 1200 fps & 8,200 PSI What I will probably do is load a box using that data then back off on the charge & run some over my chronograph, drop the velocity down to the level you recommend.
Like to shoot some sub gauge SxS events, bought a nice condition Hunter Arms “Hunter Special” 28 inch IC & Full. Had the stock bent, fits nice. Only thing is it’s light, under 7 lbs, factory target loads are hotter than it needs. Get the 20 working well may be in the market for a Parker 20.
