does porting affect hunting velocity??

[hofts]

talking about a 12 gauge here. example. if i shoot a goose on the fly at 45 yards is it going to be just as dead from a ported barrel as from a non ported barrel all other things being equal???


thanks
jj


bty i just bought a benelli cordoba, 30 inch. havent shot it yet. this will be a upland game, duck, goose, twice a year trap, skeet, sporting clays gun!! ha ha.

If I am not mistaken, all the powder should be burned in the first 24 inches or less of that barrel. Hence, there shouldn't be any loss in velocity due to the porting.

[skeet]

What fabs says is correct....actually approx 21 inches for most loads. The only real things that happen because of the porting is..one.. There will be a great increase in the perceived report of the gun. Meaning it will be a LOT louder to those near you. Even for yourself. two.. There is a small reduction in the amount of barrel rise...mostly noticeable between shots when you are firing quickly. You will probably be able to acquire the target a little quicker. In the real world of waterfowl hunting....will this make a real difference?? The answer is, of course,.....not really! Porting on a target shotgun like a skeet or doubles trap gun will help the more accomplised shooter a bit...but it takes a while to become an accomplished shotgun shooter. There is no real decrease in recoil. By the time the shot gets to the porting...the recoil level has already been determined. That is why those really neat looking ported chokes really aren't anything but another way to reduce the amount of money in your pocket:D :D

i have always wondered the same thing about overboring. if a barrel is over standard diameter is it still sending the same oomf out the barrel?

I had a 12 ga Baker Big Bore gun that I shot quite a bit. The bore size was .778 if I remember right. The same shells out of both guns now.. In a regular skeet bbl they averaged 1166...out of the Big Bore the average was 1202 Seriously..it was higher. And I have noticed the same phenomenon in a Mossberg 3 1/2 in pump. There is a bunch of info on overboring out there. Most says the velocity will usually average higher out of a larger bored gun. Oh BTW the bbl length was equal too.

I will not have a ported barrel in my gun cabinet.

I was hunting out of a blind with two brothers. The one had a ported barrel and when he shot it was deafening.

On one shot his brother thought he had taken an unsafe shot to close to his head. I think they would have come to blows if I hadn't witnessed that the shot was plenty safe.

I bought a used 835 with out ports as I have a hearing problem now. All the new ones have ported barrels.

I wonder if the ports can be sealed up with epoxy or something to stop that blast?

[fabsroman]

I have one ported gun, and that is the first Beretta that I bought which is an older model 682 Super Trap. I never thought much about the report of a ported gun until I had the pleasure of shooting with a guy shooting a ported Browning o/u with hot loads running through it. I thought the guy was shooting a canon when he pulled the trigger the first time and I was wincing every time he pulled the trigger after that. On top of it all, I was wearing ear plugs.

If a ported hunting gun doesn't connect on target with pellets, the porting blast should be enough to disorient the bird somewhat.

My buddy put a ported choke on his shotgun and we were hunting from his Go-Devil last Saturday. My left ear still hurts a little bit, we had to split up due to the muzzle blast. By the way, the choke does a fantastic job with his pattern using steel shot.

[Steverino]

While I cannot comment as to velocity changes for standard 12 ga bird loads, I did pick-up a fully rifled Hastings barrel for deer hunting with sabots in my BPS and it did reduce muzzle flip considerably and add a tremendous amount of noise. Since I wear ear protection and will be deer hunting alone, it fits my bill very nicely.

I wouldn't even consider bringing a ported gun into a blind for fear of having said gun rammed up my....well, lets put it this way...the ports would no longet be visible and I'd be walking on my tip-toes home.:D

[fabsroman]

Yeah, they can be extremely noisy in an enclosed blind like a pit blind or something with walls around it.

[tjwatty]

Yea, and try standing next to the guy in those early minutes just before sunup when the flame flashes past your face. That'll screw up your aim and make it very very clear why shooting glasses are a must.
Stand down in the blind and watch the action on your auto-loaders also, that will make you wonder how we keep from blowing ourselves up.

[fabsroman]

My dad tells a story about my uncle that occurred before I was born. Allegedly, my uncle loaded some shells either pretty hot or with the wrong powder. Anyway, everybody hunting with them could see flames coming out of my uncle's barrel in the middle of the day and it supposedly sounded like artillery.

while we are telling ported barrel noisy stories, i have a favorite. doesnt involve a shotgun though. two years ago at a public range, on the next bench over the guy was shooting and 8mm with a ported barrel, you could feel it on your face when he shot and on my bench my spotting scope would go off center every time he fired, it was unreal

until this past spring i felt the same way. but then something funny happened. i bought a chomp-n-choke tube (ported) for my o/u for spring turkey hunting. i went to pattern it and had the other barrel with a std. x-full that i had in it.
i shot a load at the patterening boards out of the c-n-c- (.670)barrel, then shot the other load out of the x-full (.685)
WOW a marked dif. in felt recoil, i had my buddy try the same thing with my gun not telling him what i was thinking. his comment back to me after firing the second shot was "did the second barrel have a hotter load in it than the first?"
so all i can say when shooting some heavy turkey loads out of my gun there was a felt difference.

[fabsroman]

Jim,

Let me guess on this one. The ported choke was on the top barrel and the unported choke was on the bottom barrel.

I could be wrong, but I am willing to guess that is how you had it set up.

The reason for my guessing that way is because the top barrel on an o/u always has more recoil than the bottom barrel, even if you use the same chokes. Clay shooters will always shoot the bottom barrel first, and if only shooting a single shot, will always use the bottom barrel.

The reason for the increased recoil out of the top barrel is because the barrel is more out of line with your shoulder. In essence, the bottom barrel pushes the gun directly back into the shooter's shoulder but the top barrel tends to rotate the gun up into the shooter's face.

The results would only be magnified by a hot turkey load out of an o/u which provides no recoil help like an auto.

Let me know if my guess is correct.

went pheasant hunting with my new benelli cordoba and i must say i absolutely love it. i have put around 150 rounds thru her and man is she sweet. eleven of us limited in a few hrs north of pierre sd. great hunt, anyway,

i have no regrets going with the 30 inch tube, i have had 28 all my life and the 30 just plain felt better to me. i use this gun 95% for hunting upland game, waterfowl, and anyway happy i made the choice i did. hell i even shot very well with it at the skeet range!.

as far as the ported barrel goes, is it louder....yes. did it affect me or anyone else pheasant hunting ......not at all. at the skeet range.....not at all.. would i take it into a pit blind with no one having ear protection........hell no.@!!!

any way, great purchase for me .. i really like the finger screw out chokes, as it was nice to quickly change from mod to cylinder when we hit a covey of huns. it is extremely smooth and reliable, and fast, and so easy to clean. i will never own gas again. but i do love my o/u's as well.

[JimHnSTL]

fabs, the first time i shot it with the ported choke on the bottom, i did however switch barrels after all this because i too have always heard the same story on o/u recoil. it felt dif. no matter which barrel i placed it in. i was realy dumbfounded. all that being said i guess i shouldn't be totaly surpised as they are able to reduce felt recoil on a lot of rifles with muzzle breaks. with the two dif. chokes in the same gun at the same time and being able to fire one right after the other really gave me the oportunity to compare. i am not advocating all ported chokes will do this, and it may be more evident in a higher load such as a turkey load but i am confident that it did something in mine. i am not a novice shotgun shooter, for years back in the early eightys i shot "Meat Shoots" with the good-o-boys for sides of beef and such. there are a lot of gimmics out there for those guys too. so i'm a bit sceptical on most claims. maybe someone else with a o/u and a c-n-c turkey choke and try it too this spring and post their results. by the way got a great pattern out of it. i'm sold on chomp-n-choke products.

Alrighty then, my assumption was incorrect. I have a ported Patternmaster choke on my SBE and never really thought there was a noticeable difference. Then again, I really didn't try it out.

I should try the experiment in one of my o/u's and see if I can feel the difference.

By the way, the hunting, fishing, and shooting sports have so many gimmics out there that it is ridiculous. I have gotten suckered a couple of times, but now I am really leery about what I buy.

[hofts]

i have never seen advertising of the patternmaster choke tubes say anything about recoil reduction. strictly tighter, more consistent patterns.

[JimHnSTL]

let me say that i bought the chokes based on pattern performance only. it wasn't until i shot a o/u back to back at two targets did i realize this. again while their was a difference in my book i really think that it has to do with the higher pressure loads. i'll have to shoot some regular loads out of the same gun and see if there is a diff. (noticeable)
