Shotgun Test How An Altered Forcing Cone Can Improve Pellet Patterns Also, take a good look at the forcing cone in a typical hunter, very short, but also very rough machining measuring 3 16" to 1 4" in length. then look at a quality clays gun forcing cone, highly polished out to the point you can hardly tell if there is any cone at all. Longer forcing cones don't make any difference. neither do longer tapers in chokes. the proof is at the patterning board. alas, very few actually know how to use the patterning board properly. if you just shoot one shot, look at the pattern and say, "hmmm, that looks like a hot core," you're wasting your time.
Are These Forcing Cones Page 2 Shotgun Forum A forum community dedicated to shotgun owners and enthusiasts including the remington, beretta, and mossberg shotguns brands. come join the discussion about optics, hunting, gunsmithing, styles, reviews, accessories, classifieds, and more!. The remington has chatter marks on the existing cone, left over from the factory, that i would like to get rid of. i have access to spiral reamer, and a 400 grit, ball forcing cone hone. the standard desired length of the cone, i have been told, is 1 1 2 inches. i think i don't want to go that far initially, as i can always go more later. My wifes turkey gun charles daly pump in 20 ga. angle porting done alot of work to the barrel, forcing cone work, polished the barrel & chamber, angle ported the barrel, 10 oz. kinetic barrel weight. indian creek special ordered 552 tube & the nitro # 7, 3". "wild turkey possesses a remarkable ability to turn arrogance into hopelessness.". The forcing cone is directly in front of the chamber, the wad and shot have a long way to go and are affected by lots of other factors, like nominal bore diameter, choke restrictions, length of choke cone, etc. too much happens after the forcing cone for it to be a major playmaker in patterns.

The forcing cone exists for one reason, and one reason only. to transition the inside of the gun barrel from the chamber diameter (about 0.800 inches) to the barrel bore diameter (nominally about 0.729 inches.) that is all. period. that little area to the right of the "b" in the diagram is the much ballyhooed forcing cone. 1.1k. posted april 1, 2012. benelliwerkes said: modifying the forcing cone, by polishing and extending the length of the barrel "cone" it allows a more gentle constriction of the shot pellets to be shaped into their pattern, usually something like a 5 degree angle of constriction immediately in front of the chamber to a 2 3 degree angle of.
