I have a question regarding the nature of HEAT warheads. I came across the following paragraph on Wikipedia, which was explaining how HEAT worked and so forth:
This got me to thinking: If rifling, which imparts spin to the projectile, decreases the effectiveness of HEAT rounds, then how does the Carl Gustav's HEAT round compensate? I know the projectile (FFV-551?) has flick-out fins once it leaves the tube, but I thought these were for stability in flight. Do they counteract the spin as well? Also, I understand that the Leopard C2's 105mm L7 rifled gun fires HEAT shells. Are these somehow compensated for spin as well, or is the article inaccurate?
I found this Army News video of an ERYX launch on the range, and it seemed to me (I could just be seeing it incorrectly) that the missile was spinning quite noticeably on its way to the target. Yet, despite the spin that i see, the missile is rated to be capable of defeating 900mm of RHA.

Can someone clarify for me whether or not spinning reduces the effectiveness of HEAT rounds? and, if so, why are some HEAT rounds able to spin and still function?
http://en.wikipedia.org/wiki/High_Explosive_Anti-TankHEAT rounds are less effective if they are spinning, the normal method for giving a shell accuracy. The centrifugal force disperses the jet, so the warhead design needs to be modified for use with rifled guns, or fired from smoothbore weapons
