Eric Cortina tuner brake true reviews?

[DngBat7]

I’m looking for real reviews on the EC muzzle brake. I am familiar with tuners. Use them on my BR rifles and love them. But curious about his brake tuner combo. I would like any negative reviews as well. Please message me privately if do to post a criticism. Thank you

I like mine and had really good results with it. I replaced an Area 419 hellfire. It reduced the same amount of recoil if not more.

Winning In The Wind, on utube, has a look into using brakes. Might look into it there

@Keith of winninginthewind posted a very good analysis of using brakes. I agre with him- it’s adding additional variable. You have to tune, re-tune, tune for particular weather. By the time I finish my tuning and finally be ready for competition, half of barrel life in case of prc will be gone.

If you like tuners, and you like brakes, you will like the tuner brake. Both features work great.

I have a couple that I am trying out.

As a brake, I would rate performance as acceptable. As a PRS shooter, there are better performing brakes out there. I have APA Fat Bastard brakes on other rifles and those definitely out perform the EC Tuner brake in regard to muzzle rise and rifle movement. The EC Tuner brake is more pleasant to be behind due to the design of the first port.

As a tuner, I have been able to improve group performance in some cases. It will not cure a poorly performing barrel. I have one barrel in particular that has shot extremely well with the EC Tuner brake installed. Two identical barrels, consecutive serial numbers, the barrel with the Tuner brake shot better across all loads tested. I cannot say that the Tuner Brake is the source of the performance for certain as the barrel in question could just be better, but it is certainly not hurting anything. I will never know for sure as I have no intention of removing the Tuner Brake to find out if another brake performs differently.

You don’t “have to”, it’s an option. If you ever travel across the Country or World and your load is not shooting well, you can do something about it rather than be up a creek.

Alright now THIS reason, makes a lot more sense why a guy would need or use a Tuner.
Different geographic loctions and totally different conditions than their usual home range.

is there any information or videos on adjusting the tuner brake?

Erik Cortina has several videos on U-tube explaining how he tunes with the tuner/brake and tuner alone.

In my most humble of opinions, I think that may be a little bit of paralysis from analysis.

Yup. It’s like Russell’s paradox, isn’t it?

I don’t see the similarities but that thing gives me a migraine. So could be?

I have one on my 6x47 Borden mountaineer action/Bartlein barrel. Absolutely love it. Shot the best group of my life with it. Worked the best load I could reloading then tweaked the tuner a bit a left it there.

Tuners do not solve problems, but they are the best tool we have to treat symptoms. If your barrel doesn’t shoot, if your reloading process is not fine tuned, and if your shooting fundamentals are not there, a tuner won’t fix any of that. But as Eric said, if you are at a range far from home and can’t change seating depth, powder charge or use another primer, a tuner might save your day. It is just a tool. You don’t have to use it, but if you need it, it’s there.
Erics tuner and tuner brakes are well designed and carefully machined. Good stuff!

Started out using Erik's tuner brakes but since my most recoil generating rifle is a 260AI BR I decided neither of my rifles generated enough recoil to warrant a brake. Swapped over to the V2 tuner as soon as they came out and have enjoyed working with them all. Have no regrets of adding them to my rifles and never plan to be without them. If there is a drawback with tuners it does take time and effort to go out and shoot in different conditions to learn why and how to turn it properly. After the best load development is done instead of reaching up and trying to wring the threads out of it one soon finds it only takes a small movement if any at all to keep the rifle in tune if maintaining the same load as the tuning was accomplished with. KEEPING the rifle in tune is the key to success with it. And that is the more difficult portion of the knowledge to gain.

It's pretty simple, not different than powder charge or seating depth tuning.

Put a witness
mark on barrel to keep track of
tuner adjustments. Start at 0 and
move up from there when tuning.
Shoot groups in increments of five
on the tuner to find best settings.
Look for two good consecutive
settings, then put tuner in middle of
two best setting for most stable
results.

You can't go wrong with the EC tuner.

Will the tuner improve groups on a heavy bbl? Think M24? I’m sure the brake would help but wondering if I would get benefits by adding the tuner as well?

Yes
