BVAMP, I doubt seriously that the original poster was interested in improving his patterns. Your comment didn't address either patterns or recoil reduction, just stated flatly that "you shouldn't have your barrel ported on anything but a rifled slug barrel, or a NON CHOKED barrel." No explanation. No facts to back it up. Not particularly useful to the ongoing discussion. I pointed that out although I probably should have done so without a personal attack. I did NOT advocate Cutts Compensators for Saigas. I did explain my understanding of how they function since it had been questioned i

My experience with the Saiga 20 is that it is slightly picky about the ammunition it is fed. It isn't a matter of the power of the load, it is a matter of the shape/size of the rim of the shotshells. My Saiga 20 won't run the cheap Winchester's at all. The cheap (Wal-Mart) Federals ran pretty well until I ported the barrel (now they don't run at all). Fiochi shells run just fine. The extractor on my S20 had some burrs on it that held onto some shells (depending on the shape of the rim). I've polished out the burrs and I hope that will allow the shotgun to run with other brands of shotshel

BVAMP once again adds a useless and meaningless reply. There is no harm to having a ported barrel, smooth/rifled/choked/non-choked or otherwise. As several people have said, the gas pressure at the muzzle of a shotgun is MUCH less than in a pistol or a rifle. Because the pressure is so much lower muzzle brakes are much less effective on shotguns than they are on pistols or rifles. ("BRAKES" as in applying braking pressure, not "BREAKS" as in breaking something.) Porting is somewhat more effective since it starts farther away from the muzzle where there is more gas pressure. But, porti
