extreme

[Doctor Lecter]

anyone on here shoot the extreme chokes ? 

 

[Charliedog]

sorry not personally but I understand they are very good and may possibly of originally/still produced the Kreighoff titanium which are top notch

 

[k80ben]

Have lots of these in my cabinet and also many clients with them. 
 

what’s the question

basically do you rate them ?  or is it just bling ? 

 

[k80ben]

Those and briley are the best

A choke is a tube of smooth interior that constricts the exit way of a barrel.most chokes i have seen are between say three and four inches in length and there will be no difference between makes to the naked eye.i would ask what makes a aftermarket choke any better than the gun makers own.the constriction surely must be the same  in each of the range regardles of who manufactured them.1/4 choke is a 1/4 choke whatever way you look at it surely.

Unfortunately it doesn’t work like that

It's a fair point, come to think about it.

Granted, different manufacture materials/product lengths will effect weight of choke and therefore gun balance and I've read that ported chokes hold wads back to reduce muzzle flip, better patterns etc but surely, accurate constriction should be uniform (1/4, 1/2, skeet etc)...and then it's just choke type (flush, ported etc) as the variable ?

To that end, if all after market manufacturers are working to the same spec in a like for like comparision, (constriction, ported or not, extended or flush etc) they should be much a muchness? 

In any instance; choke constriction, brand, flush/extended etc doesn't make one iota to me and the level I shoot at but it would be interesting to hear a more expert opinion on the matter and what the actual difference between manufactures are?

Could you please explain why it doesn’t work like that, I appreciate that you have a great deal more experience than most of us but how can one manufacturer make a choke tube work better than the others?

They are. There’s so much nonsense talked about chokes it’s criminal. Manufacturers invent bold claims about choke performance that have no grounding in reality. Like many other aspects of our sport, it’s marketing nonsense that too many fall for.

Sure, there’s advantages to titanium over steel when it comes to weight and extended over flush when it comes to convenience but from a performance point of view, absolutely nothing. Anyone that says differently is probably trying to sell you a choke.

Chokes from different manufacturers in an ideal world shouldn't be any different. However everything is always made to a tolerance. A 1/4 choke should be a 10 thou restriction from the bore diameter. A Browning 12Ga with Invector Plus chokes should be have a bore diameter of 0.740", so a 1/4 choke should taper to 0.730". Neither the gun or the choke will be exactly those dimensions. They wont be far off, but they will be off. I imagine that the choke internal dimensions are machined by a reamer and the choke held in a chuck or collet in a lathe? Is the reamer worn? is the collet/chuck/choke perfectly central? What's the surface finish on the inside of the choke? Tighter manufacturing tolerances = higher prices. Even the length of the choke might make a difference. A 10 thou restriction on an internal choke might be different angle to a 10 thou restriction on a extended choke, which I imagine will affect the pattern. How much are these tolerances and angles going to affect the shot pattern? Probably not much, but they will. Using a harder/softer lead shot will probably change it more.

Using a stepped choke gauge is to measure them going to be a waste of time as well. A LM choked Browning should be 0.725". That's 2 thou smaller than a cylinder bored Benelli.

All ported chokes do is clog up with powder and plastic fouling  and make them harder to clean .  This comment is based on having owned Rhino chokes donkey’s years ago when they were fashionable ( I’ve still got half a dozen k80 ones somewhere )  . I’ve even had a gun ported by spark erosion ( through GMK ) when it was fashionable to do so  . It made no difference at all to perceived muzzle flip , it just made it noisy and harder to clean.

My question was what makes aftermarket any better.your reply is a little short on technical detail.

It's a steel tube....what more can we say on the matter ......other than it ain't rocket science

So by your reckoning there could not be any difference let alone one be better than another.

Correct.  ...imo it's a steel tube that restricts the exit of 400 ish lead balls from the barrell.....anyone telling me there is any major science in that is deluded....in my humble opinion

Unfortunately it doesn’t work like that 

So how does it work ? how can one steal tube effect the exit of approx 400 balls of lead any differently / better than any any other steal tube ????

 

[k80ben]

As usual the same people try and act like they know something when they actually don’t. 
 

I’ve shot nearly every choke ever made and all have huge differences. Rhino and extreme are very centre dense so appear to hit harder. Briley are much more even spread over the board. 
 

high end Guns like Krieghoff and blaser now outsource there choke to aftermarket systems because that’s what they specialise in. 
 

all In all yes there’s a difference 

 

[Will Hewland]

There is only one variable that I can think of between two different chokes of the same overall constriction and that is the shape of the taper. For example one might be a straight cone shaped taper from thread end to muzzle end while another might be more progressive, with perhaps a parallel last section. Other variants are possible of course. A longer choke would give more scope for shaping the constriction. I’d still be surprised to see a big difference but it would be good to know what these shapes are in different chokes (if they do vary).

I've got 2 Light Mod chokes in front of me now. Different manufacturers, both extended, although there is a 0.080" (approx 2 mm for the young 'uns) difference in length. They are manufactured for a Invector Plus, nominally bored to 0.740", and should taper to 0.725" (0.015" for LM) .  One tapers from 0.742" to 0.7235, the other tapers from 0.750" to 0.724". I'll get them on the pattern plate next time I'm out, and report back
