For the sake of discussion, let's assume that the sliding friction in a 2" barrel is 1 pound.
In a combustion, average forwards force is around 30psi - 90 pounds - IIRC.

So, we are talking about 1% potential energy gain. That's about .5% potential velocity gain.

You get that much gain by making the barrel .5" longer... if you see my point.

i see your point, so are you saying if you used anti-barrel-friction(this product does not exist to my knowledge)everytime you shot this anti friction crap would have the same effect as if you made the barrel 1/2" longer?so you might as well make your barrel 1/2" longer then using some anti friction crap.
