tuner alter your barrel ?

[Link]

When you screw a tuner or brake on the end of a HV barrel does it change the barrel in a bad way?
Not talking about how a tuner or break works but the ''shape'' of the barrel.
How important is it to torque them on the same every time?
I hope I explained what I'm asking? lol

A tuner does nothing bad to a barrel. It is important to set it where it shoots. If you remove it, put it back in the same place.

My smith wants tight threads. You don’t want a rattle at the end of your barrel. Because my tuner threads are tight, I don’t always snug the tuner screws and when I forget to do so, I have not noticed a difference.
I screw the tuner all the way on and then back off at least one complete turn to zero and snug it there until I have the load tuned. Screwing the tuner on and off after that does not affect the tune as long as I set it in the same place. I swap a tuner from one barrel to another and then back with zero change in poi.

The general consensus is a tuner will not turn a mediocre barrel into a great barrel, but will allow you to get the very best out of what any barrel was born with.

If any tuner believers have a believable test showing that you can go from out of tune, to in tune, back out, back in… i’d love to see it.

there is a huge amount of snakeoil in the tuner market currently about “no load development, just buy a tuner”. i’ve yet to see anything on paper that i can believe actually showing that or the effect of a tuner in a already tuned load for that matter.

all you benchrest nuts must do A/B testing you believe in, please share!

No one on here has said that just buying a tuner will get you there. In fact, when I started Mike Ezell told me what all of the guys echo- develop the load and then use the tuner to keep it in tune.

This is my first tuner test. They are all three shot groups shot at 100 yards. I did the test after developing the load.

My First Tuner Test

About six months ago I bought a used barrel with a Woolum tuner on it from of the site. After weeks of trying for consistency with my Bat 3l, I decided what the heck, I might as well spin the barrel off and give the barrel with the tuner a try. I did no load work up to speak of. Just measured...

Have you ever tested a tuner? If so, please share your documented results.

 

[Terry]

When I got my first tuner I did my seating depth test, and powder load test, with and without the tuner. Every test with the tuner shot smaller. I found that I could turn the tuner two clicks right or left and get a snowman laying down or standing. I have found that I can adjust the tuner during the sight in period and change the impacts on target.

That’s a great test - best I’ve ever seen by a lot!

Don’t get me wrong, I’m not saying most people here are “selling” a tuner as a replacement for load dev, but it’s clearly happening in the bigger pond of shooting.

I have a tuner brake on order to test myself to see what happens. I’ll certainly be doing a bunch of testing and my shooting is diff than yours so will be interesting to see what (if any) effect it has. For example, my groups aren’t tight enough to trust 3 shots as believable so I always shoot 5.

Hard to know if it’s me or the gun introducing the worst shot, but if a tuner both give them and taketh away, I’ll know it’s the gun. If there is no change, I can’t rule out the tuner as being ineffective, maybe because of my shooting discipline sim the limiting factor. But a lot of guying shooting like I do seem to suddenly want tuners, I haven’t seen anything close you your results to justify it.

Without the tuner on the gun, or with the tuner set at a nominal “zero”?

Actually you can prove it yourself if you have a tuner, fix a target with 24 or so separate dots for POI, set your tuner and shoot 3 shots, move the tuner 1 mark and repeat, move 1 mark and repeat, as you do this you'll see the POI group in different spots, I'm not the best to explain this but maybe @gunsandgunsmithing can chime in, it really makes a difference. EDIT: Sorry didn't read the whole thread and just saw the test. This is what I was talking about.

Both, tested w/o tuner, and with tuner turned out one full turn, then to zero.

I posted this a while back, not a test, but a good example of how a tuner helps.

Shout out to Mike Ezell

how did you pattern tuner while it was in tune? I'm confused by your question. I'm happy to try and help but we've got to be on the same page in terms of what tuners do. I must be misunderstanding your post because reading group size and shape is 99% of using a tuner...and yes, you have to know...

Look above - we cross posted in time. That’s my plan. Given my current capabilities, which are very different than a 6ppc, I’m def interested in seeing how much it will matter.

Here is an example of what I’m working with currently. I’ve never consistently (4+ groups of 5) been able to shoot groups that don’t end up in the .4’s all averaged. But I can manage to keep a load with .2 variance in charge and .020 depth change all within that range too.

I would expect (most of the time) the ideal load to change if you hang the tuner on the barrel at any setting, versus no tuner. Did you retune the load after putting tuner on or just go with best non-tuner load?

Admittedly, I am NOT the best at tuning. However, as you can see, a good tuner can and will make a difference.
With any new tune, I will pattern the tuner to make sure I understand what the target looks like “in tune” and “out of tune”

The post above are pictures from my tuner notebook. I keep detailed notes to myself on the tuners on each rifle. This notebook is in my shooting bag at all times.

I came up with the same answer both ways. The best load and seating depth, was best both ways.

Now that is super interesting Terry - thanks for following up!

 

[Uthink Uknow]

I do the same, Mulligan, minus the targets. I write in the DA at the time of the individual match, the tuner setting(s) and the score. I have a separate page for each match as the DA, the tuner settings, and the scores change from target to target.

Shrinking groups from .5 to .25 at 600 is significant! Thats approx the starting range I’m at now, so is probably most similar I’ve seen to my current shooting. Opposed to trying to squeeze .1 to .0 at 100 short range, which is awesome, but different
