Well, I finally used up all my AA-8700 and you can't get the stuff anymore. Long story short this stuff had a burn rate in the same neighborhood as the double digit reloader series powders that start with "2" but still had good ignition and stable burn at pressure levels all the way down to just south of the 20-K pressure mark provided one used a full case compressed load in a medium size rifle case.
Absolutely perfect stuff for loading plain base WW-alloy rifle boolit loads in 8x57, 308, 8mm-06, 7.62x54R, 303-brit, etc. and pushing them with a gentle long burn curve.
So I'm looking for another powder wit a similar burn rate that will also have stable ignition and burn properties at much lower then normal operating pressures. Most won't and cough, sputter, and blooper load if you try to load them like this with the goal of producing lower peak pressure full barrel length gentle burn curves in non-magnum case sizes.
Anyone out there know one or two that don't? I already know about R-17 and am aware that it has the stable low pressure ignition and burn properties I seek but it is still a lot faster burn rate then what I'm looking for to replace AA-8700. Works great for 7.62x39 and 30-30 case size 100+% case fill compressed loads but is too fast to do this with for the larger medium case sizes gathered around the 30-06 size bracket; I need something slower that has stable ignition and burn properties all the down to 20-K pressure levels like AA-8700 had.
