fred, I understand your point.
Long range rifle shooters with ,, custom barrels ,, custom actions ,, wildcat calibers, etc.. play with OAL , max powder charge,, brand of primers,,, etc. etc.
Bullseye pistol shooters wanted enough powder to work the action ,, be accurate,, and punch a hole in a paper target at 50 ft.
USPSA shooters have to make power factor with the least amount of recoil. Years ago they pushed 38 super and even 9mm Way past the suggested max.. ( and still do )
Shotgun reloading manual indicate the loading recipes should be strictly followed with no substitutions .
So, when you are a newbie ,, or even an old fart that has been reloading for years,, and one manual stating 6 grs of XYZ is max.. one saids 8 grs. is max. ,,, and one saids 10 grs.
Is starting at 10% less ,,, 5.4 grs. or 9 grs. ??
I've been reloading for 40 + years and sometimes the reloading manuals have me scratching my head and wonder WTH ??
