Default Porting A Shotgun Barrel?

The other day at the range I saw a guy with an old break action 12G with a bunch of holes drilled in the barrel. I had to ask the guy what the story was. Anyway long story short I shot the gun and maybe it was my imagination but recoil did feel lighter. I used my shells ,Super-X 00. Do you think it's a good idea to try it with a Mossberg?

my ported gun just helps eliminate muzzle jump, not recoil.

Porting does nothing to reduce recoil. From studies that I have read, the recoil pulse has been generated as the shot begins to move forward and clears the chamber/forcing cone area, long before it reach the muzzle. It might help with muzzle jump, but only if the porting is angled upward/backwards.
As for porting your Mossberg - save your money. It will not help you and it is not cheap.

I jest, there is some science on muzzle jump, but frankly, all I notice is damn ported shotguns are loud for the people around you. I won't buy a ported shotgun.

I've had a couple of them in the past. It does cut down on muzzle flip, but it's more of a novelty than anything else IMO. That and those little holes tend to catch and build up plastic from the wad cups with heavy use, rendering them ineffective on top of being a b!tch to clean.

Save your money, and look for a ported barrel on the used rack at the LGS if you want to try it out at some point. I have seen ported M 500 or 870 barrels at my LGS for less than the cost of having it done by a smith.

I won't own one. The holes get grubby fast.
