point and shoot Posted March 19, 2011 Report Share Posted March 19, 2011 What are they supposed to do and do they in fact do it! Are they worth the investment or is it just a sales ploy!

chrispti Posted March 19, 2011 Report Share Posted March 19, 2011 Possibly act in the same way as a ported barrel and slightly reduce muzzle flip Quote Link to comment Share on other sites More sharing options...
wacker Posted March 19, 2011 Report Share Posted March 19, 2011 No - i had some, people standing to the side said they were quite noisy when i fired, they also are a pain to keep clean, as they get very cruddy. Quote Link to comment Share on other sites More sharing options...

Gordon R Posted March 19, 2011 Report Share Posted March 19, 2011 They cannot reduce muzzle flip. Anyone who says they can is delusional. The after-market choke sellers must rub their hands when people repeat their claims. Ported chokes vent pressure in every direction, not just upwards. The only porting that can reduce muzzle flip is the banana shaped porting, done by Nigel Teague. They funnel pressure upwards, reducing the tendency to flip the barrels upwards. Ported chokes are a pig to clean - I have 4 of them. They look okay, but are pointless in reality. Quote Link to comment Share on other sites More sharing options...

Ported chokes are a pig to clean - I have 4 of them. They look okay, but are pointless in reality. We meet again on this contentious issue Gordon... A ported choke will vent gasses all around, true. However, that does mean that a lot of that highest gas pressure, at the point of muzzle flash, is dissipated in a 360 degree circle perpendicular to the main charge. This means, unavoidably, that there is less of the 'muzzle-flash' gas energy to generate muzzle-flash gas recoil at the emergence of the shot charge, bullet, whatever. This is simple physics. And undeniable. Muzzle flash gas is a big factor in recoil, it's the main reason why shorter barreled guns recoil more, even if you add more total weight elsewhere you'll still have a harder kicking gun than a similar weighted longer barrel. So with a ported choke, you will have less recoil, and less muzzle flip as muzzle flip is very dependent on recoil. I do accept most will never see the difference. They are slightly longer to clean, I don't think a perfectionist would mind. They are worth it on autoloader shotguns, imho. Quote Link to comment Share on other sites More sharing options...
HDAV Posted March 21, 2011 Report Share Posted March 21, 2011 Why worth it on semi's? ( which have low recoil anyway? Lighter?) I have ported chokes on my O/U Quote Link to comment Share on other sites More sharing options...
point and shoot Posted March 21, 2011 Author Report Share Posted March 21, 2011 Quite a lively debate but yes - why good on semi's? Quote Link to comment Share on other sites More sharing options...
killer_pigeon Posted March 21, 2011 Report Share Posted March 21, 2011 i was told they strip the plastic wadding away, giving a better shot pattern, not sure if its true but my ported chokes smash clays much better then my normal extended ones. cleaning is a simple 2 minute job with KG1 carbon cleaner and a toothbrush wouldnt change mine now Quote Link to comment Share on other sites More sharing options...
poorpeet Posted March 21, 2011 Report Share Posted March 21, 2011 I shoot better with them than I do with the std chokes. I accept it may all be 'in the mind' but who cares? Quote Link to comment Share on other sites More sharing options...

This logic applies if there was a normal choke, or no choke. You couldn't make it up. :lol: :lol: Quote Link to comment Share on other sites More sharing options...

A muzzle flash at the crowned edge of a non-ported muzzle, be it on a shotgun or rifle or pistol, releases instantly at once and hence far more violently than the much more progressive, tapered release (time -v- pressure) via the small ports of a ported choke. I'm right. Quote Link to comment Share on other sites More sharing options...
Catweazle Posted March 21, 2011 Report Share Posted March 21, 2011 (edited) You couldn't make it up. :lol: :lol: Apparently someone can Actually, it kind of makes sense though. When the gas goes out sideways through the ports there is still metal in front of it, so it's acting both forward and backwards and cancelling some of its effect out. Maybe.

Chokemeister Posted March 21, 2011 Report Share Posted March 21, 2011 Quite a lively debate but yes - why good on semi's? You have one barrel compared to an o/u or s/s, less inertia to dampen any flip. I think they would appreciate anything that reduces muzzle flip more for a quicker second shot. I noticed the difference on my auto'. I even added weight to my muzzle end and had an even better second shot. Each to their own I suppose, but to claim it's all placebo effect is just wrong.

When the gas goes out sideways through the ports there is still metal in front of it, so it's acting both forward and backwards and cancelling some of its effect out. Maybe. It does exactly that. The gasses dissipate energy much more slowly (time v pressure) through the smaller choke ports than they would releasing all that energy at once, at the 'big 12-bore hole' at the muzzle. This is maths and physics stuff, nobody is being a smart-****. Quote Link to comment Share on other sites More sharing options...
Scully Posted March 21, 2011 Report Share Posted March 21, 2011 I have a Rhino extended 'ported' choke for my 11-87 and it throws excellent patterns.I'm aware of the science behind the design,but can't say I'm aware of reduced muzzle-flip.I prefer to shoot with it than with the convential choke of the same restriction. One of my handguns had a ported barrel...target and sight recovery was increased significantly for follow-up shots even with full weight loads.

Catweazle Posted March 21, 2011 Report Share Posted March 21, 2011 One of my handguns had a ported barrel...target and sight recovery was increased significantly for follow-up shots even with full weight loads. I'll guess that the ports were on the top though, and possibly angled slightly backwards. Some shotgun ported chokes have holes all around.

point and shoot Posted March 22, 2011 Author Report Share Posted March 22, 2011 Thanks for all your input chaps. Reading between the lines, are we now agreed that a ported choke is a benefit to muzzle flip and better patterns? Les Quote Link to comment Share on other sites More sharing options...
HDAV Posted March 22, 2011 Report Share Posted March 22, 2011 Thanks for all your input chaps. Reading between the lines, are we now agreed that a ported choke is a benefit to muzzle flip and better patterns? Les yes i contacted Teague and got this reply Ported chokes will give slightly less muzzle flip. Also they are designed to hold the wad back slightly, thus giving the wad less interference with the shot pattern. Quote Link to comment Share on other sites More sharing options...
DSPUK Posted March 22, 2011 Report Share Posted March 22, 2011 I would imagine Teague would tell you anything you want to hear. - OK we have had theory so can someone lend me a Rhino 1/2 mobile choke so I can do some field investigation for a year or two.

Guest cookoff013 Posted March 23, 2011 Report Share Posted March 23, 2011 they are a hard to clean gimmick. but they sure do look nice. make the gun stand out. Quote Link to comment Share on other sites More sharing options...
figgy Posted March 23, 2011 Report Share Posted March 23, 2011 I think It would be better to have the barrels ported and use whatever choke you like that way you know it's going to work. Or if you don't want to alter your gun buy the chokes you want to use in the extended variety,tighten them in mark the top of the chokes and port the chokes yourself,top half only or the v pattern as used on gun barrels. Might have a go myself if i get some cheap ones. ATB figgy Quote Link to comment Share on other sites More sharing options...
