I can tell you this, everything I've researched & was told leads me to believe that ball powder burns cooler than extruded. That should be easier on you throat wouldn't it?
If that proves to be true of course...
I'm no subject matter expert of course. After all, the 6-284 is a mythical fire-breathing barrel eating monster whose appetite knows no bounds. & whose soul purpose is to enforce the theory of diminishing returns & skepticism
Sorry, Sorry... that is my attempt at humor.
As far as loads for Ramshot Magnum goes, I'm running a long action & SMK's are seated at 3.100". With a Fed210M:
start at 54.5grns (~3150fps & low pressure) & work up from there. If I recall correctly, the muzzle velocity I used in my ballistic app to meet my 1100yd dope is right at 3400 or just over.
