Tuna can

Why aren't all the groups the same size? Well, it's important to remember that it's not unusual for most lots of ammo such as SK Rifle Match and RWS Target Rifle to produce various group sizes. Someone online told me that.
Also, these groups were shot on different days, under very different conditions. Different lots of ammo, different temperatures, different barrel condition etc etc. It's almost as if those factors might make a difference in how a rifle shoots....
I saw you latest post in the 1/2 inch challenge. Why aren't all your groups the same size? Did you use different lots of ammo? Did you shoot the groups on different days? Under different environmental conditions?
I'm not shooting a Benchrest caliber rifle, nor top end ammunition. Shockingly enough, ammo that costs $96.49/500 isn't quite as good as ammo at $227.49/500. I'm not using Benchrest equipment like a front rest and rear bag. And I am not a Benchrest shooter.
And yet groups with other settings are averaging significantly larger..... Why don't you try re-wording that, but using the average size of groups at various settings?
The point of the tuner is that it changes barrel harmonics. Groups are supposed to get bigger and smaller, as you change the setting. The absolute size of the groups has very little to do with the tuner, and is more related to the rifle and ammo. How the groups change size as you adjust the tuner is the whole point.
I repeat, evidence of the tuner having an impact is shown by how the groups change size with different settings, not the absolute size of the groups.
As I said before, this rifle and ammo averaged 0.6" without the tuner. With the tuner set to the appropriate position, this rifle and ammo averages 0.353". The average of all other settings is 0.613".
Alpheus, a tuner works primarily to reduce vertical spread caused differences in MV between rounds. Your tuner results show considerable vertical spread.
Shoot ten five-shot groups with a box of ammo without the tuner. Shoot ten more groups using the tuner at the setting you believe works to reduce vertical spread. If the vertical spread is reduced appreciably, there may be something to it. Keep in mind that this is still a relatively small sample size. Any single group that's smaller means nothing on its own as it may be a random act of accuracy.

Has anyone tried these on sleeved barrels? IE CF or Alum?
I just tested 1 different setting/per rotation with my 16" CF barrel (10/22 w/8x magnification - 10 shots @50m) and will be testing the 3 "inbetween" settings next trip and then whichever gives me the smallest vertical I'll test .2 above and below the "winner".
I started with it set at "#32" with it grouping at 2" vertical. Setting "#22" went down to .5" and setting "#12" went back to 1.5". Next time will be 37, 27, 17.
I'll have these groups all on the same target and can post a photo once complete.
I actually shot 10 rounds at 462m with it on setting #12 which resulted in a 10" tall group (8 rounds but not including 1 flyer@6" above the rest and 2 shots to get the wind correct that went into the dirt). I'm excited to see what I get once it is tuned properly.
Also....this is all with CCI Blazer & 8x magnification (*TunaRoll*)
Between paroxysms of laughter, perhaps you can direct him to the results elsewhere. There aren't any convincing results shown in this thread -- at least not yet.
As noted previously, tuner results that work must be repeatable and not simply a few groups here and there.
If anyone has data showing Tuna can results that are verified by repeatable succeess, please post them or offer directions to find them.

I smile when some keep asking for "proof"... when given, then it is not enough... prove it again... well, it needs to be proven more.. or better... Rinse and repeat.
visit a larger rimfire PRS match across Canada and you will see many of these in use (or other versions). Maybe we are all delusional (as shooting out to 400yds with a rimfire must indicate). Maybe these are just placebo and make many shooters feel better in their delusions????
Want data that satisfies ones views... buy it, test it... show us your real world results.
Asking for examples and then nit picking the data is getting boring. don't like how it is presented, spend the money, do the work and show us your results.
I have been testing since 2018 and my testing/data includes 12 barrels (likely forgotten a few) in various formats and counting.... got a question... spend the money.. figure it out. I have shot cases of ammo in the testing. Imagine how many rds have been sent by ALL the shooters across Canada mucking about with these 'delusional toys'. Me thinks, that is one hell of a large sample size. Oh, forget about the many more shooters on the southern side of our border...
For those that want to learn about real world LR rimfire shooting, pm or email. There are places where the process is discussed by those who are actually doing things and want to move the tech forward.
YMMV

Tuners seem to be finding fans in the F class world
wonder what that is all about????

Keep smiling, Jerry, because you've missed the point. Despite posters claiming to have posted proof in this very thread, there's none to be found.
To be sure, there may be those who've posted "proof" elsewhere, but not here -- and that's precisely what I'm saying. Perhaps you might read more of the thread.

Re read my post and you will get the point.
Look forward to seeing your data.

Jesus you two get a room and make up. Just agree to disagree. You both go at it, on every 22 rimfire thread that talks about accuracy.
I bought a tuna can but will never post my results as they will simply be torn apart or dismissed as irrelevant. Or they don't fit the narrative of some random person on the internet.
Life is too short.
