I've been considering buying a Perazzi Mirage trap gun. Both the upper and lower barrels appear to be Pro-ported. Does anyone know if porting really works at diminishing actual recoil, perceived recoil and muzzle jump or does it just take a nice gun and devalue it? Also, I have always wondered if there was a barrel obstruction distal to or beyond the ports, such as snow, mud or a wad, if the porting would help prevent a barrel bulge? Thanks for your opinion. Addendum: Is there any scientificic evidence porting actually reduces the force of recoil or is it only perceived recoil? Also, an observation I have made while trap shooting, and this phenomenon seems worse with trap doubles....if there is a strong headwind, i.e., wind blowing in your face....20 knots or greater, then serious smoke is blown into one's face and eyes. To me this is a serious detriment and offsets much gain from other benefit, such as reduction in perceived recoil.

i had two o/u ported,in my humble opinion it worked.a beretta sporting clays that i still shoot when i `m not shooting lc`s had forcing cones and porting to both barrels.it does help with muzzle jump and also think it does with recoil.i`msure you will get many responces telling otherwise but htat`s what i think.

Yes, it works
Yes, it is ugly
Yes, I do NOT own a ported gun except for the
EIGHT Cutts guns in my stable

I have a ported 12 ga. Citori, and another that is not. I don't perceive much difference in recoil or muzzle jump between the two shotguns. I use both for sporting clays and skeet.

I wouldn't pay to have one ported. Likewise, I wouldn't pass on a shotgun purchase just because it was ported.

In my opinion, not much difference.

In a shotgun, not much.

In a rifle, a lot.

It's all about the weight and velocity of the gas being redirected.

Shotgunjones hit the nail square on the head. The total recoil is based on the weight of the total ejecta, which includes the powder gases & the velocity it is ejected. The percentage of the powder charge in proportion to the projectile is much lower in a shotgun than most centerfire rifles, plus the rifle will normally have a higher muzzle pressure than the shotgun.
Porting works by diverting gasses which would normally eject forward being diverted outward, thus not adding to the recoil.
In a shotgun though the portion of the recoilbrought on by the powder gasses is much lower than in the rifle, so not as much to work with there, & you won't get it all anyway.

I agree with everything said above. Not much more to say.

I don't think it helps much in actual recoil as mentioned above, but it can help in felt recoil by not getting popped as hard in the cheek. I think there's a real value to decreased muzzle jump in just about any clay target doubles game.

From what I know, there's a bunch more surface area on most shotgun porting than rifle porting. So, I believe there is compensation for the decreased velocity of the redirected gasses by bleeding off more.

Lately, I'd rather bird hunt and can't stand porting in general, but when I shot a lot of doubles trap, it made a huge difference.

I had 2 sets of the same barrel configuration. 1 barrel I had the lower barrel ported, you're not going to notice anything until you move up into pigeon loads. Between 4 shooters we coldn't notice anyting with clay loads that included Handicap loads also. Once we got into the 3.5drm loads there was less muzzle jump, with the 3 3/4drm loads yep. But I gave them up years ago, at the end of the day it's a waste.
