Anyone here have muller 16 gauge invector chokes?
Do you like them or have you had problems with them ?

I do have Muller chokes in my Citori. I like them. I have never had a problem with them. When I clean the barrels (about every 500 rounds) I remove them, clean the threads and put Superlube grease on them.

I also have a set of Mullers for my Benelli SS, they are about 5 years old.. They have many thousands of rounds through them. No problems. I take care of them just like the Mullers in the Citori.

Just know that you can not use steel, tungsten and the harder no-toxic shot in these choke tubes.

Muller does make tubes that can handle steel, tungsten etc.....but they are not available for the 16 Gauge Invector system.

What shot size have you shot threw your invector ?

Joined: 04 Mar 2019 Posts: 1837 Location: Central ND

1350 FPS. 7/8 oz. #8's & #7 1/2's

1300 FPS 1 oz. # 7 1/2

1275 FPS 1 1/8 oz. #6's

All lead. I have also shot a few buffered bismuth loads of #5's for patterning purposes through the U3.

I am guessing you have either heard/read bad stuff or you uneasy with aluminum choke tubes. If you read the stuff on SWG, I would ignore it.

All I can tell you is Mullers pattern nicely and with a little care you won't have any problems.

Ok that makes me feel better lol. I talked to I think his name was Jimmy yesterday and he said 7 1/2 and 8s and off the record he said 6s should be fine in lead only of course.

I actually bought the last 2 complete sets to be sold. The 16 gauge invector are now discontinued. He has a couple U4 U1 U0 left but I got the last 2 U2 and U3s. He is a super nice guy! He actually had to make a couple of phone calls to get me 2 complete sets put together.

Well I am glad that you talked with Jimmy. I have shot sporting with him more than a few times. That was how I got started with Muller chokes. He has a few more gray hairs when he got involved making 16 Gauge Invector chokes. I was one of the guys that emailed him to make chokes for the 16.......and he still talks to me!! He is originally from CT and still comes up this way now and again to visit and shoot.

You will like the chokes.

He was awesome to deal with for sure! I was only going to buy one set till he told me he could only complete 2 sets and that was the end of the 16 gauge line. So I figured I had better buy both sets just incase I ever break one lol.

Yeah I hear that. I have a U0, U1, a pair of U2's and a U3.

That shouid take care of Sporting, hunting and a little skeet.

Well thank you for your time! I really feel good about my purchase. The 6 shot had me a little worried but now that I know someone has had success with 6s I'm happy!

Before I spent almost $100 for a choke tube highly recommend that you read Neil Winston's testing of Muller chokes.

https://www.trapshooters.com/threads/choke-question.834021/page-7#post-7873995

I first met and shot with Neil at the Steer and Calf shoot in Mn. about 15 years ago. Unfortunately he recently passed away. He had a Masters in Statistical Analysis and that is exactly what patterns are, statistics. And he patterned and tested shotgun patterns for choke, powder, primers, shot hardness, etc. more than anyone else before or since his death.

As he said and I agree until someone else comes along and proves otherwise his results are facts. So far no one has been able to prove him wrong. At least not with scientific data.

Readers digest version of Muller, factory, and Briley chokes compared to each other if you're not into statistics:

Result. All the chokes produced similarly hot-centered patterns, as do all others with similar pattern percentages.

Summary.

Three chokes of different brands, length, materials, and design were tested. The patterns they produced did not differ in

A: Pattern percentage in a 30-inch circle.
B. Seventy-five percent diameter, “pattern spread.”
C. Central thickening, pattern “hotness.” Confirmed by analysis by another method.
D. “Consistency” as measured by Standard Deviations of all these characteristics.

Conclusion: All three chokes performed equally and well.

He did the same testing for the even more expensive Brain, Muller and OEM chokes with the same results.

I am as guilty as the next shooter and have at least 3 shoe boxes of choke tubes. Mainly OEM, trulock, and Briley. If I had it to do over again I would not.

But that 6" between a shooters ears is a dangerous place. And if you think a certain brand choke will help you then by all means go for it.

Cold Iron, thank you very much for your input. I read the article and it is very educational.

Cold Iron,

The original Browning 16 ga. Invector tubes whether skeet, I/C or modified all toss approximately the same pattern with the I/C throwing tighter patterns than the modified. At least that is what happened with my Citori and A5.

I went to Trulock and tried their tubes with about the same result although at least the modified shot the tightest pattern.

That's why I went to Muller. Muller choke tubes are unlike Briley and Trulock which are spaced about 0.005" apart between tubes.

So the Browing tubes measured

Cylinder +0.002"
Skeet 1 -0.006"
I/C -0.006"
Modified -0.009"
Full -0.041"

Trulock measured

I/C -0.007"
Skeet 2 -0.014"
Modified -0.019"

Mullers measure

U1 -0.004"
U2 -0.012"
U3 -0.023"

Sorry I don't have a U0. I have 2 - U1's, 2 - U2's and a U3

In this instance there is a real issue with the original tubes. Trulock didn't put a lot of effort into fixing the issue either. When I talked to the guy at Trulock the only thing he could offer was for me to send back the tubes.

All I can tell you is that Muller put some time and effort into addressing the problem with the original system. Muller chokes are made so that when you change chokes you actually change something.

When I get my Citori stock back from TronSpace I will pattern the Muller tubes.

Mark, what Muller tube do you like for hunting? My tightest Briley on my shorty barrel is .012" which would be a U2 I guess.

With my Citori I have been hunting with U1 and U3.

I haven't tried the U2 tube for hunting, but honestly i don't see why that wouldn't work except maybe for really long shots......and even then.

My 1100 always has the 0.015" tube in it for hunting and I never thought it needed more.
