Just ran across this and well....not very impressed.... with your testing of this product. By going from 0 to 1/4 to 1/2 to 3/4 to 0, you probably skipped over quite a few nodes. If you were to change seating depth by .01" instead of .002", the same kind of results would show up. Just what do you think the numbers on the scale were for? Oh, and you did not go back to zero as the weight keeps moving so you actually were at 10. So, you were not going to give it chance from the start so maybe you have a beef with EC??. You seemed so surprised to see the big harmonics shift when you put it on the first rifle. What do you think was going to happen? Even the shift on the next rifle going from your brake to the EC brake, was a change in harmonics as the weight distribution of the two brakes are completely different. I guess you did not review the instructions and even videos of others people testing. I know from my experience on my 300 WSM with a factory load Norma Bondstrike 180gr the group went from 1" to under 1/2". To be clear, I am not disparaging your shooting or reloading capabilities, but just the review of the tuner/brake. As far as the EP5, it is fine for me.

I ran mine with 6.5 cm aguila 140bthp, just as a test, and it DID tighten up the groups, I have only shot 5 settings thus far. I shot them in 2 click increments, saw it get better, still not done desting it with the same ammo. My testing shows improvements. Your mileage may vary.

Hi Mike. Good video, the results surprised me. I didn't think that load was that good. Lol. Now I just need to get a good one for my GT. I had issues with the firing pin/ spring. Got new ones today.

You still have to load develop which includes seating depth...even with a tuner. Factory ammo gets you 1/2" groups or better with a tuner, handloading gets you 1/4" or better with a tuner.

Does the EC tuner only turn out 1 turn? With a rifle shooting as good as your 2 no need for a turner. What reticle are you using in your NF?

Thank you for telling the truth about the arken, i am so tired of all these folks saying that arken is the best thing since sliced bread, when you can’t spot your impacts with it. A scope is a lot more than loud turrets.

2 questions. For the Load that was "worked up by the old owner," did you Chrono the load to verify low SD ES. 2ND question, did you tighten down the jam nut on EC Tuner or just screw it on there?

I just recently came across your channel when doing research on carbon rings. Love your work so far, definitely going to watch more of it. One gun channel to another, solid sub from me.

Love your channel brother

Hi Mike! nice video, you should try the 6.5 without the muzzle break ! i think it would group way better

I love coming here because I know the information is straight. I have two 6.5 creeds and they are both under . 300" off of my loads. And they both got there by me keeping it as simple as possible. To me, simple = consistent. To me, this device is a variable variable, if that makes any sense. Thank you for the straight test.

Also is the idea of this more so for a crutch for factory ammo and essentially tuning the gun to the ammo? You have essentially tuned the ammo to the gun, then changed the gun so it would make sense that it would have been more ideal being setup the same way the load was developed. Would be interesting to see the same test done with factory loads.

I think most people who claim their cheap scope is as good as a tier1 scope really haven't looked thru good glass. I understand muzzle whip and how a tuner can adjust for harmonics in the barrel as a bullet is fired, honestly though, I still scratch my head though on how well they perform, thanks for the video Mike, well done sir

GREAT VIDEO MIKE... !!!!! BREAK OR TUNER ...? ? ? MY 300 WEATHERBY ..? ? FIRST SHOT POPPED MY NECK ... !!!!!! AFTER MUZZLE BRAKE... MAYBE A 30-06 ... LOVE THAT GUN ... !!!!!!! LIKE ALWAYS...!!!! LOVE THIS VIDEO .... !!!! YOU CAN TELL BY THE CAPS ... DOUBLE G. ...!!!

I took the EC Tuner Brake off of my gun because the tension screws would not hold the setting and kept moving. I don't think it improved groups much. But to be honest I got tired of screwing with it and a little more time may have helped. So for me it was just adding something that could go wrong.

The tuner is going to change poi as it weighs different than the other setup. I have two. It’s a tool to go along with your other processes. Turning the brake only 1 complete turn may not give optimal results. This review doesn’t give an accurate overview of the EC product. You can’t get an accurate read on a load by only adjusting powder charge by 2gr sometimes. That brake is the same way. I personally used it to take a 1.5moa gun to a 1/4moa gun so it works. You may have to tinker as with any new component is all I’m saying. My 2c if it’s worth anything

Kencarpenter said it all !

Why skip the 3/4 setting?

Iv never wanted a tuner. Handloading is the way to go

One more baseline after the test would have been interesting.

Hi Mike just came across the channel I’d do some more research and retest The test you did was unorthodox lots of info out there your supposed to go buy tge numbers and work your way out not just crank it in turns. Yours skipping over nodes ect

do a seating depth first , then a load development and then your tuner adjustment. when adjusting your tuner start at 0 and move the tuner 1/15th forward and shoot 5 shot groups. tuners sit in two places on the barrels. on the end or over the barrel and the only difference is the amount of the revolutions. try Harrels tuner/brakes :) look much nicer on barrels !

TREX did an exhaustive review with testing equipment, clarity IMO is dependent on the shooter. My guess it's prob due to handling of light

like your dog

And it really is laughable, people equating a three tier scope 1 tier. You know how many companies would be going out of business if that were really the case? I agree, the EP5 is an excellent! Sub $700 rifle scope. And there is only one exception for me where a 2-tier scope is in the hunt with a 1 tier and that is the toric ELR. I love this scope!

Tuners change poi. The EC Tuner Brake has more than 4 settings.

Not being unreal just trying to state what I have learned about the ec tuner you are doing everything wrong according to how Erik says set it up. If you do like he says it will shrink your groups as I have put them on cheap hunting rifles and brought them down from 1 moa and larger down to 1/2 to 1/4 moa. My son in law just shot a .1 group with a cva cascade which is not the norm it usually shoots .4 but without tuner it's over 1 moa.

Not a great comparison !!! Doing quarter turns is waaaay too big, you could quite easily be jumping over nodes !!! You doing this is like developing a load and jumping full grains of powder, then saying ooooohhhhh that powder is crap !!

Why didn’t you actually go through the whole tuning process to actually do it justice and show how it actually works?

If you intentionally use any product incorrectly then of course its not going to work. Its not the tuner that's the problem it's the user.

One of the main benefits of the EC tuner is for competition shooters that travel. your environmentals change, so therefore, you have an ability to tune where you’re at when you cannot tune your load being preloaded and or for winter summer shoots as well when temp fluctuates 50deg. There is a reason you see them at a lot of matches .

Flawed test. You’re not supposed to adjust in quarter and half turns.

Haalarious.

You skipped half the settings and clearly did not follow the instructions.

Tuners aren't worth it. Eric Cortina has a lot of fans and they wanna support him by buying and promoting his products; that's perfectly understandable. Insulting people who disprove the usefulness of his products doesn't help Cortina's integrity. If the tuner isn't working because you're not sticking your tongue out right then tuners just isn't worth the hassle.

You replicated Bryan Litz's findings on tuners. Shoot groups with and without the tuner. You'll see the same results. You're not doing anything wrong. Tuners do nothing.

You were already tuned into a load. The tuner is made to improve harmonics with loads that aren't that great. I can't even believe you even comparing glass either. The video was a waste of time and ammo for what the tuner is for. How do you improve on 3 bullets touching.... ?

IT APEARS USELESS TO ME.... NO TUNER 4 ME

This panther hollow is a barrel of fun, what a pessimistic know it all. He should start his own manufacturing of optics and gun components.
