Why the "war" on Ported barrels??

Barrel porting, especially on O\U Trap grades was quite popular at one.
I may not be totally correct. But my understanding was that it helped control muzzle during doubles shooting. And some claimed that it reduced recoil. I can certainly understand the former, but always questioned the latter.
In any case, it seems to be terribly unpopular these days. Perhaps some of you could explain this to me? I can't imagine what porting could do to make a barrel so undesirable.
Any guidance would be appreciated.

 

Same reason 26” barrels aren’t seen much anymore on the skeet field.
Trend.

 

just trap is correct "trend" and also inaccurate criticism. Companies like pro port have done studies on porting and advantages of porting....while others say unproven negative statements.

 

Shooting next a ported gun really is a pain in the "EAR" also getting sprayed @ times is fun either, AND if porting was advantageous ALL the big shooters & olympic shooters would be using it

 

I like my ported barrels. Doesn't seem any louder and I've never had anyone next to me get "sprayed". I don't think it helps you break the target, but I don't see how they hurt.

 

Do we need a seperate class for ported barrels?

 

It all depends on the type of porting , bad porting can cause pieces of plastic to be thrown, and some ported guns are really loud

 

countless times shooting protecters ben sprayed by porting !!!!

 

Sprayed ? With what ?

 

Plastic wad pieces or unburned powder hitting my legs when I was wearing shorts

 

Porting doesn't do anything meaningful for a shotgun.
They make the gun harder to clean. They disperse more sound to the side of the gun making it sound louder.

 

shooting games a ported barrel is almost as next to an auto loader.

 

I don't understand the "making it harder to clean" comment. I've never - never - cleaned the ports of any of my guns so configured. I don't really believe that porting has any real material affect in the guns performance, loudness, or deflection of muzzle jump. I only had one gun sent to get ported and that was 30 years ago. If the porting holes close up so be it. But . . . I've not experienced that as an issue - the holes stay open although they do get a little rough around the edges from carbon build up.

As far as the decibel level on my ported guns, none of my squad mates complain. However, they are never very happy when I show up on the skeet range with my Cutts Compensated 12 ga Remington 1100.
