6BRA Ladder Test with/wo Tuner

[BartsBullets]

Shot this ladder test today at 100 yards. I did it with a twist ie 3 shot groups instead of 1 shot.

I also ran the test with a tuner on the barrel and then without (bottom target). All I changed was powder.

What do you think!

30.6g?

31.6 w/no tuner is where it’s at for me! Stretch it out tomorrow and let us know how it does.

I think 30.6 has the barrel exiting in the same place & with the ES of 1 using the tuner i would play with it there ( the tuner ) if you are OK with the speed...

For long range i would say 30.5 is looking friendly and deserves another look. For short range, I’m tagging in to learn.
I know nothing about tuners!

31.6 and move the tuner. What I'm saying is, try 31.6 with the tuner and tune it to shoot small by moving the tuner..but we're comparing apples to oranges. Node looks widest of all, at 30.5 with tuner.
Did you re-adjust the scope when you took the tuner off? I'm looking at poi also.

 

[Mulligan]

Why did you only shoot one shot at the 31.6 on the bottom row?? Trouble counting? Did the pooch call your name about then?


Tom

Dang it Tom, its distracting with both hands on the bra!

Yeah That was a good one. But .2 more and it went to Hell!

Why does the comment, “Tom, put on your BRA and go shoot!” Come to mind!

30.6g?

With H4895, absolutely, that's where I run mine at and she bugholes.

 

[BartsBullets]

I’m thinking 30.5 30.6 shot great but 30.8 is CRAP! So not to get too close to the edge.

But 31.6 is tempting!

well my take comparing both ladders is this for long Range work. the tuner in my experience is less volatile when there is a vertical blow up vs non tuner but what i gain and these targets are re enforcing is this in regard to the tuner ladder, what you gain in loss of vertical dispersion shows up on the other side in the form of horizontal sensitivity or stringing, the tuner will dampen barrel compensation making a tune look broader but is less willing at distance to shoot extra small as the non tuner application will give. non tuner reads for me as follows more volatile in vertical dispersion blow ups when in the wrong spot but has a powder ladder trend i like to see for 1000 yard work. i would choose none of those charges for 1000 yards but a dissection of a couple. these are great Ladders and explain a lot to me.

Yes I did readjust the scope when I took the tuner off. The first shot with the tuner off hit about .5 higher then where it was printing with it on.

Something thats been on my mind lately... Tuners work, but we dont have a clue what they actually do. We typically picture a barrel and tuner like a tube with a weight on the end. I think that is WRONG! These targets show the opposite of what we have read over the years. Tuners do not make nodes wider, increase the amplitude or reduce frequency. I have seen this exact thing happen when hanging a weight from the muzzle end. Nodes are the same distance apart and in the same place. My opinion is we still have very little idea of what is happening to a barrel when the bullet is in the bore...
For long range I like the looks of the target without the tuner... 30.6 or 31.8 ish

they change the shape and response of the frequency simple as that Alex, those ladders are very different how subtle they may be but they are very different. i would agree that it has a narrower ability in my experience at distance but at short range can be more beneficial. we still have very little idea exactly what is going on with the tuner not being in play from a matter a fact perspective.

Exactly, very different in the opposite way we have thought they worked. We have looked at tuners and barrel harmonics like a weight on the end of a tube. I have seen enough for me to say, that ain't how it works.

how who thought they worked? the masses ? not at all my thoughts but it appears we agree some how Lol..

Shawn Williams

PS I read lots of shit on theory or fact that doesn't line up with my real life results..

 

[Curious]

Can we really read anything into this when the ladder was shot at 100yds?

 

[dmoran]

My input, based from my own experience, if that test was a "shoot through @ 100/1000", the 1000yd POI's would likely tell a different story, as well as yield more obvious results. With vertical dispersion being the significant difference to why.

Vibration analysis proves that you are inded, wrong. I won't debate that as, there is no point. It is a FACT that they lower frequency.

 

[moondog]

30.6 is where mine really came to life. Both at 100 yards and 500 yards. I was able to repeat the results over 3 strings. 3955fps.
27" tube.

 

[gunsandgunsmithing]

If they lower frequency why do the nodes not change distance apart or position? I have seen that happen many times. I have even dont that at 1k. ladders with and without a muzzle weight, node did not move.

What tuners do, is they change where the muzzle is when the bullet reaches the crown. The can not do this without changing the frequency.
