Many years ago when i bought my first chronograph i figured out that MANY times even the max load in a load book (especially the older books) actually gave NO improvement in gained fps.. over a load that was 1/2 grain less powder!! And, in many cases the extra powder actually caused the velocity to go down, with VERY erratic velocity from shot to shot!!!

Loading over MAX, "even if" you gained 50 fps, (wich i doupt you will) what would you ACTUALLY gain at 100 or 200 yards?????????????? All you will "really gain" is more stress on the gun and brass, for for pretty much ZERO gain!!!! To be blunt, it's a STUPID idea!!
