Semisane - interesting work.

From your previous posts I gather those are 3 shot groups @ 100 with a scope? What is the twist rate of the Lyman Mustang? How did you get such precise numbers on the "volumn" measurements? One thing your tests make me wonder is whether there are multiple performance points for a given combination. For instance, maybe a gun dislikes 70,75 grains, likes 80 grains, dislikes 85,90,95,100 then likes 105. Interesting stuff. Thanks.
