Cowboy action shooters have a big saloon fight over polishing chambers ever so often. It's to the point where it is assumed that chambers have to be mirror bright and wollowed out before they will function. Anyone who suggest otherwise is ridden out of town on a rail.
There are some that point to evidence that rough chambers actually release the hull better than smooth chambers as the roughness leaves space between hull and chamber wall.
The same reasoning behind ribbed hulls. Ribbed hulls is the next saloon fight with the weight going to smooth Remington STS hull and the smooth Winchester AAs.
Mary and I shoot Stoeger double barrel shotguns with factory stock chambers and anything and everything falls out of the chambers nicely. We stay out of that saloon.
