>>64502508 (OP)
there is an optimal spin for a bullet op based on weight, length, diameter from memory I think its miller formula(just checked...wrong it is the miller twist rule). There are more subtelties like how gyroscopic force is effected by the core of the bullet being hollow or having a lighter material etc etc but the main point is there is an optimal spin rate for a certain bullet and you would gain nothing much from your proposal but I stand to be corrected, spin too fast and the bullet won't follow the arc trajectory, faster rpm would just diminish accuracy so there is an ideal range of rpms between the slowest and fastest for given bullet. Just adding more RPMs above the ideal range would be bad. Most efforts in rifling aim to impart the idea RPM while also reducing velocity as little as possible. A secondary factor is barrel vibration and tuning, imagine a light whippy stick that you flick around and how the end of the stick moves, now imagine a heavy thick stick, the end does not whip around (many accuracy barrels are heavy for this reason but all barrels have whip and a multi wave vibration pattern. For accuracy nuts like me this can be tuned out by carefully handloading and adding weight at an ecact point on the end of the barrel..imagine tying a lead weight to the end of your whippy stick..see, the end whips around less. By spinning the barrel you would cause the barrel whip to spray bullets much less predicably and cause chaos with barrel harmonics.

I don't want to discourage your inventiveness but just give you an idea of the wonderful complexcity you are begining to understand. Consider reading
"The Gun and Its Development by Greener W W,
Which I think (you check I think it has many of the early formulas in it. ). Of course formulas imroved and got even more exacting, a classic is 1910 is "Lehrbuch der Ballistik" (Textbook of Ballistics) Karl Julius Cranz,
