I'm picking one up in 5/8-24 and can always throw it on the rimfire if I need to. Just need a thread converter.I am glad I bought one and actually buying another. LOL
I only use 2 shots. As you can see from my pics you can watch them getting closer. I check with a 5 shot group after I find the setting but not needed for dialing in the tuner.
Do you see a noticable difference in your 5 round groups pre-tuner versus your "dialed in" tuner 5 round groups?
Definitely do. One of the lots I tuned was close to a 3/4 moa lot and after it was one hole.

I'm glad l held off on ordering one. Thanks for the input everyone. I guess my money would be better spent elsewhere right now but I plan on revisiting the idea at a later date.
Cortina made a video using an AR and his new brake tuner.Has anyone tried one on an AR? I know an AR has a ton of other factors/variables going into shooting groups, but since you can't really play with seating depth on an AR, a tuner should provide some improvement. The way I see it, an AR would really test the effectiveness of a tuner.
Thought I’d share my results.
I bought this because I have access to factory ammo that I would shoot in a pinch. Also liked the idea of finding a node, keeping it, and fine tuning the tuner instead of seating depth.
Here’s my results:

How to read the target:
-top left number is target number
-bottom number is indicated hash mark starting from just off flush
- targets with / weren’t used and Z we’re just zero confwith mine and other rifles.
-all targets have 3 shots except 11 and 13, which I know I made a bad shot and just put an extra one down to confirm
Started just off flush as instructions said, and started to dial 2 hash marks at a time. I chose to do 3 shot groups because I felt like 2 wouldn’t tell the whole truth.
You can clearly see the groups start tightening up as I get closer to what I found worked (-10) and then start widening once I went out of the sweet spot (-6). So I started dialing back in single hash increments and thought I had found it at -7. I shot 4 to confirm because I knew I had pulled a bad shot causing that flyer on target 11. However, I decided to double check the set screw and found it had loosened up quite a bit. My error. So I tightened it back down, went to confirm and it was opening back up. Which made sense because as you can see on the target the sweet spot in right around -10 to -12.
So I started going back in single increments to -10 and found it tightened right back up. Made sure set screw was screwed on good this time, then shot two more confirmations(16,17).
To me, it really does work. And since I plan on switching between ammo, I’m hoping to have these settings marked down for each one so I can make those changes quick, confirm, and be ready to shoot.
PROS
-you can tighten up your groups without having to mess around on the bench (more my style, I’d rather be outside shooting!)
-super easy to install, no modifications needed on the rifle
-it hit rule number 1, it looks cool as fuck!
-price, to me $200 is t bad for what this thing does without having to change ANYTHING. You literally just slap it on
CONS
-as frank said, be prepared to use a lot of ammo. Hopefully the more use this thing gets in the public, someone will find a new, quick method in determining what to dial
-directions could maybe use a little more clarification or edit, but that could just be me
-you need to have patience and a good chunk of time dedicated to determining your setting. I was getting a little antsy toward the end and was at the range longer than I had expected to be
I haven’t had the chance to shoot factory yet and change settings between factory and hand loads, but I am impressed with it so far. I really like it and will be buying one for my .338lm
I must have been doing something wrong with my other rifles as I could not see any improvement. I haven't given up on the tuner but just skeptical at this point in time.
I'm waiting on a QB can to put on my rifle. Once I get the new can on, I'll re-zero the rifle.
This is the group with the old suppressor but without the tuner. It's an 8 shot group with factory Hornady 6.5 CM 147 ELDM.
I don't feel like wasting ammunition to improve on this group if it won't get any better than this. Should I try using the tuner or be content with what I'm getting?

I would think for a guy shooting factory ammo this tuner would be ideal?! But I guess if he’s already getting 1/2 moa 8-shot groups there’s little room or need for improvement
I have to say the process drove me crazy I was not prepared mentally for wasting this many rounds at 100 yards... it broke my brain
The biggest bitch was, before I started my test group looked like this:
View attachment 7528726
So I am starting from a point here, and then the groups were going big, smaller, not quite small enough, bigger, it drove me nuts. I hated it playing with it.
I threw a ton of fliers too that made me hate it even more and question the entire process. Is that ME or the tuner doing it, is that two in one hole and a 3rd, is that group good enough or should I try more. The mental aspect of this process should not be overlooked.
Then to make matters worse, my suppressor came loose twice, once the can, and it's an OSS Reverse thread, I think initially there was some contact I missed. Then the brake loosened up so I took it off and started over.
Another brain breaker, trying do to it on a 8x11 sheet of paper. I did not go to my range, I met Chris Way at a local 200 yard range near Denver. I had built a target at my range, like many above, used a 3/8" orange pasty, spread wide apart. Doing it on a single sheet made it a mess personally. I hated it.
Now all that said, that is all me, I can see these working but at what point, The idea is simple enough, David Tubb talked about it with his brake, moving the self timing brake back and forth to tune.
So it actually lends to ideas.
I shot way too many rounds for about a 1/4" increase, so in my mind this is the perfect factory gun fix, or seating depth replacement. I know speaking to a Palma Shooter they talked internal Ballistics a ton. Chasing lands, chasing barrel, to me here is where the tuners would shine.
I think the thing that killed me mentally was when a group got bigger. If I threw a round farther than before. Almost every group was just one round out there, 90% were two round in one hole, one round out, so you are Constantly questioning your own shooting. E Blah I hate the amount of ammo I was shooting at paper.
But I plan on moving forward, I think I might cherry pick rifles to use, my Bartlein barrels don't really need it initially
And for me not having all my kit with me, no spotter, you have to literally walk down every single shot. I had actually missed a perfect stopping point because from behind the rifle I didn't see what I thought I did, (didn't have my prescription glasses with me either, total operator error, self induced clusterfuck ). so I could have been finished in like 18 rounds and been happy, instead of 68 rounds ... and stopping.
No.I'm going to confirm my groups next time I'm out but if I'm shooting 1/2" groups, is this something I need to mess with?
Tuners work good for most people. You need to ensure you are a good shooter to begin with. It's not some secret sauce to make things magically be a work record beater.
In my case, even though I reload, I was able to keep the coal and use the tuner to tighten the group. This was a 3.7 coal that fed good and couldn’t be lengthened and was already a slightly compressed load so couldn’t be shortened
I'll disagree somewhat here. 'Good reloading practices' is doing a lot of work in your statement and often what it would call for isn't practical. The key advantage of a tuner is being able to tune in pre-loaded ammo (factory or handloads) immediately.You also need to still have good ammo, good barrel and good chamber to get good groups.
A tuner is not a miracle device. A tuner will not make a bad load shoot good. It will not turn a bad barrel or bad chamber job into a better shooter.
What it allegedly does is make the harmonics of a load potentially more optimal for your barrel (if it isn't already optimized). But you still need all of the above in order to produce good groups.
It's essentially a crutch for making good factory ammo that perhaps isn't optimized harmonically to your barrel/chamber more optimal. If you reload, a tuner isn't going to do anything for you that good reloading practices won't solve.
