When you are running guns like 1911s in 38 Super, porting is a noticeable advantage. The relative volume of gas generated in a small bore with a Super, et als is quite different than what is generated in a 12 gauge barrel. I shot IPSC for many years and all my hand guns were ported and it lead me to have an earlier shotgun or two ported which was a mistake and waste of money.
 
Out of curiosity, who on this thread has ever competed at the highest level of classification (AAA/Master/27) in any of the clay target sports?

Looking at the photos of the SC US Open going on now, an overwhelming majority of those likely to podium or place high in Master have porting.

Berry- Rhino
Kienbaum- Rhino (bottom barrel only on his current gun/set of barrels)
Kruse- Rhino
Wolf- Rhino
Mears- Rhino
Moon- Factory Krieghoff
Kidd- Rhino
Powell- Briley
Ribbs- Briley?
McGuire- CompNChoke

The only ones I see that aren't are Wilgus (who has swapped around guns/barrels/stocks a few times in the last handful of years), and Fanizzi (autoloader). Can't find a current picture of Wendell Cherry, but he's definitely gone back and forth.

And although he's in Paris, Mein has Rhino porting as well.
 
I talked about this before, but I'm just dying to talk some more. DO NOT WASTE YOUR MONEY ON PORTING!!! there, I said it... had two identical 1100s had one ported, shot both back to back extensively in different orders but with same ammo in each and methodically tried different shot sizes, speeds, and weights til my shoulders hurt (which is hard to do on an 1100) and multiple times in different seasons. Not because I'm really that scientific, but because I was angry I had been taken a rube. It was expensive, I could have spent the money on countless other better things. Figure out a way to load confetti into the ports so your financial losses will at least be festive. Film it too so we can all mourn your barrel! 🎉🎉🎉
Ps, I forgot to mention I had a 870 done same time too. No difference, none.
 
Realistically porting doesn’t do much one way or another. There are quite a few older, ported Citoris in the market that are rock solid guns and priced right.

“The holes used in most barrel porting are fairly small, and a series of holes are used to increase the total porting hole area to the bore area or even slightly larger. However, it is very difficult to get high pressure gas to flow through a small orifice. The higher the pressure and the smaller the orifice the more likely the flow will be "choked," that is, restricted from flowing freely. In order to be really effective, the size and number of barrel ports would have to be very large.”
 
I`m trying to wrap my head around why the mfg`s would add a extra machining process step, which adds extra cost to the barrel set if they thought there was zero benefit from doing so.
I`m no fan one way or the other, however there has to be more to it than meets the eye

How many of them have physically paid for the service to be performed?
Asking for a friend.
