Red Knob Tuna Can vs EC Tuner V2 - Whats Your Experience

I’m thinking about adding a tuner to my rifles - CZ457 .22LR and Savage Axis II Precision .243. Some of the guys at my range are using the Red Knob and really like the results. I just saw Eric Cortina’s EC V2 tuner on YouTube. What’s your experience with either or both of these tuners? Or is something else out there that you deem to be better than the above tuners.
 
Never tried the EC tuner, but I do have a tuna can on my Vudoo 22LR.

I cannot say for sure that it helps with accuracy, but I would not say it hurts either.

I like the tuna can because of its weight. It helps balance my rifle for CRPS matches.
 
I believe JC custom barrels has started making tuners.

There are a few different tuner manufacturers but the bigger issue is finding ones that can ship to Canada.
 
I have been experimenting with a tuner on my 6.5CM.
So far I was able to get 3 rounds in the .2’s at 100M, a few different ways even.
I find my 100M accuracy does not match at 300M however, so it’s a work in progress still.
 
CZ's 1/2x20 oddball threading limits the options for the 457. I know Red Nobb threads for them, but most companies offer 1/2x28.
No experience with the V2 but I have an EC Tuner brake on a 6GT and the machining is perfect. Brake + tuner all in one package, and aesthetically pretty. If you already have a brake then the V2, Kinetic Security Solutions, Spearhead etc should all work.

Spearhead sells an adapter for European threads
 
Based on feedback from people on this forum and others, it would appear I’m better off investing in more precision ammo than buying a tuner. In shooting rimfire precision, I don’t think I need to re-tune every time I meet the guys at the range for a bit of friendly competition. Sounds more like a PITA than a benefit.

I don't know where your getting that you have to retune every time. Generally it's tune to a certain lot and leave it. Sometimes it's not even necessary with lot changes. But if your shooting cheap ammo your definitely better off trying better ammo first and a few different ones to see what the rifle likes the best. As for centerfire get into reloading and tune your load to your rifle, even then there is alot of top benchrest and fclass guys that see benefits from tuners.

glad you come to some sense about this.
mark my words: people who own tuner(s) will tell you how good/amazing they are and how much difference they make, regardless whether it's true or not.
I am the only one who owned 3 and still own 2 tuners and tell you this: you are better off with a washer or a nut which you can buy a dozen for $2 from homedepot
And those who said tuners are good stuff will refute my claim by saying: 1. my tuners are piece of crap, or 2. my rifles are crap, or 3. the ammo I use are crap, or 4. my shooting skill is a crap, or 5. I don't know how to use tuners, or 6. all of above.

Well I guess you better call all the top benchrest and fclass shooters in the world and tell them to get rid of their tuners.

In your case you may just have a rifle that doesn't respond to tuners .

Correction: I have 5 rifles that don’t respond to 3 tuners.
Tuner is not only a myth but more a superstitious ritual to those fclass and bench rest competitors.

Jqian, you should send me your 2 spare and apparently unwanted, mythical tuners and rid yourself of the curse they seem to have brought you.... I'm happy to pay for the shipping and your time to go to the post office.
 
I can believe a tuner makes great ammo even better. But if your ammo has inherent inconsistency owing to variation in the actual ammunition, I have my doubts it will eliminate that.
