My theory was the rifling had trouble biting into the faster rounds, which would then slide across without picking up as much spin, and I'd end up shooting knuckle balls. (which was probably compounded by the fact that my slug gun had a short barrel). 3" shells probably are generally faster than 2 3/4.
I switched from a 12 to a 20 gauge a few years ago, and am glad I did. I actually enjoy shooting my slug gun now.
***Okay, I see where you're coming from in that there could be a problem with no spin due to velocity being too high for certain ammo to use the rifling like it's designed to impart spin and stability to the projectile. I guess, therefore like the previous member stated, that there would be "slippage", rather than spinning being imparted.
