Freedom, I found an artical in shooting times(may 1996) by Mike Venturino today on reduced loads. As far as powders go he recomends the faster burning rifle powders including:
-Imr's sr4759 and 4198
-xmp 5744
-accurate's reloader7, 2400 and h4198
-with rl-7 and h4198 he recomends 17 to 18 grains with 6mm remington to 308, 21 grains in 3006 sized cases, and 22 grains in magnums.
-with the faster ones on his list (sr 4759,xmp-5744,2400 etc.) he likes 12 to 14 grains with the 6mm to 308, add a grain for 3006 sized, and another for magnums
In a 7mm-08 he used 18 grains of h4198 with a 137gr rn cast bullet for 1239 fps. Since imr4198 and h4198 are number 60 and 59 on lee's burning rate chart you are probably right on the money
