Porting a Shotgun barrel
 

I am thinking about buying a Savage 220 20 gauge an would like to know if I could get the barrel ported and if the noise from the blast was tolerable? Thanks for any input

I have two 12 gauges that are ported, increased noise is tolerable but I really didn't see much in recoil reduction...A 20 shouldn't need to be ported...

Replace the recoil pad with a Pachmayr Decelerator pad.

You'll be amazed !!!

You don't port a shotgun barrel to reduce recoil. It isn't going to happen. Barrel wall is too thin to offer enough surface area for the gases to push against and the pressures are too low to offer a significant decrease in recoil anyway (see below).

You port a shotgun barrel to reduce muzzle rise, allowing the shooter to acquire the second or third target quicker. The gases vent through the top of the barrel and push the muzzle down.

Although the noise levels are higher in a ported shotgun barrel it isn't like the sharp ear splitting crack of a braked rifle barrel. A shotgun is only operating at 10,000 - 11,000 psi where as a high power rifle is operating at 55,000 - 65,000 psi so the expelling gases are moving at a much lower velocity inside a shotgun barrel. Also by the time the gases reach the muzzle the pressure levels inside the barrel have dropped to just a couple thousand psi.

Pros of Porting
Porting results in a reduction of recoil and a reduction in muzzle climb. The recoil reduction comes from the fact that some of the hot gases that would normally help propel the shotgun backward against the shooter’s shoulder (recoil) are instead directed out of the port holes.

I sometimes see porting on the side of a barrel (in terms of the gases helping to reduse muzzle rise), so I had to research that further - check it out.............FYI

I have hunted with a 210 (12 gauge) for years. I do not consider the recoil to be noticable. When you see that deer, your adrenalin is pumping and generally you only fire one shot. With the 20 gauge, even magnums cannot be worse than the 12.

Save your money and use it on a good scope or a trigger job. My trigger pull was 9 1/2 lbs! After you fire at your first deer, see if you remember the recoil.
