Ill look up to see if theres any real life downsides to rifling.
The only one I aware of the top of my head is if the shell or bullet or whatever your firing is spinning too fast it can damage the bullet considerably.
After looking all I found was what I already know and stated above this line.
Quote:Excessive rotational speed can exceed the bullet's designed limits and the resulting centrifugal force can cause the bullet to disintegrate radially during flight
(From wikipedia, but I already knew it from other sources so its likely correct)

So im thinking we could have a max shell accuracy boost from number of rifle barrels before the shell just stops working correctly?

That's not really how it works. The rotational speed of a projectile is controlled almost entirely by the twist rate of the rifling. Basically, how many inches/cm of barrel per 1 full rotation of the rifling itself. This is denoted as something like 1:14" or one rotation per 14 inches of barrel. There are a huge number of factors that influence the optimum rifling rate such as projectile velocity(influenced heavily by weight), projectile length(also has a connection with weight, longer projectile means more material=more weight), projectile weight itself, and many other factors. There are some rifling twist rates that are more universal than others as to the variety of bullets that can be accurately fired.

Longer Projectile need a faster spin than shorter projectiles due to them being quite a bit more unstable. Also, it is extremely rare for bullets to approach anywhere near exploding due to spin outside of extreme manufacturing defects. Ordinary rifle bullets often spin at more than 100,000RPM anyway, so spin shouldn't be an issue.

I think a more realistic penalty would be to force a specific shell shell length for individual guns defined by the first shell loaded. Shells with any other variation in length or velocity would be progressively more inaccurate as length/velocity difference increased. You wouldn't be able to use a "universal" gun that was only concerned with muzzle velocity like is possible now, but be more constrained to what battleships had to deal with.

That does certainly make sense as a penalty. I like it.
