Centerfire Barrel Tuners/ Muzzle Devices

[memilanuk]

Can you get the barrel on and off ok with the tuner installed?

Jim,

Haven't tried yet... mainly as I don't have the new barrel in hand yet. Should be here this weekend - fingers crossed!

I imagine as long as as the barrel nut wrench will pass over the tuner it should be fine. If not... I've seen more than one wrench 'modified' to suit a purpose - they're not that expensive. Guess we'll find out... the gun won't fit in the air line case without removing the barrel from the action, so I'll have to work something out!

It doesn't make any difference to remove and reinstall the tuner. I removed barrel #1, a Brux, on my .300 WSM before Raton this year. I had a developed load and tuner setting. A Krieger was installed and I shot it for two months. In September, I reinstalled the Brux and took it to the range with the previous load. Even though I ran another series to check tuner settings, the same setting performed best. That barrel won the California Long Range Championship and Twentynine Palms LR Regional with that setting.

But would you be comfortable taking the tuner off the barrel, flying somewhere for a match, putting the tuner back on, when your only 'check' that it was indeed back in the same place might be your sighters? Granted, this last February I got to shoot my gun a little for a zero check after re-assembly, but a busy public range like Ben Avery wasn't what I would consider ideal conditions even for that. Seems like it'd make more sense to leave the tuner on if at all possible...

 

[Steve Blair]

Monte, I agree and do as you suggest. I just haven't seen any change after R&R.

I skimmed all 10 pages and might have missed it, but which of these tuners would work with a 1" diameter barrel that was threaded 5/8x24 for a suppressor/muzzle brake?

My barrel is a 26" 6.5x47 Rock Creek.

My tuner would work. I cloud set it back far enough to clear the existing threads and allow you to use suppressor/muzzle break at the same time if desired.

Erik, I take it you don't use a 5/8x24 thread?

 

[qbert]

Erik,

Do you have a website? Could this be done without sending my barrel in?

No I don't.

The barrel has to be machined for the tuner. I could send you the tuner and you can have someone local install it for you.

did someone manage to put a magneto speed chronograph "on top" of the tuner and figure out how it worked ? Of course, we can remove tuner, find a sweep spot with proper velocity and then put tuner back on but would like to "read" speed with the tuner on it.

 

[Quest-QC]

Monte, which bullet are you gonna be working on with the tuner ?

A tuner has no affect on velocity.

maybe but as i'm new to tuner, i would like to run some test to "learn" the impact of a tuner on my setup.

[br]Are you concerned that your rifle might shoot more accurately?

 

[Keith Glasscock]

Ok, I've been lurking on this thread a while. I'm interested in doing this to a new barrel I'm having done next month.

Erik and Steve:

How does the atmospheric situation affect tuner setting? Do you need to make adjustments when the temp swings significantly? (I'm thinking 25+ degrees). Under what situations have you seen the need to adjust the tuner? I assume when you have a new load, but what about over the life of a barrel?

How many rounds are you expending, and at what ranges are you shooting to set your tuners?

Thanks,
Keith

Keith, [br]
Short range BR shooters use tuners a little differently than we do. I think they change the setting fairly often. My approach is to develop a tolerant load, set the tuner and forget about it. Barrel #1, a Brux on my .300 WSM, just gave up the ghost this weekend. When I got home and borescoped it, it looked like there were four copper bars about four inches long at the muzzle. It has 1661 on it, not surprising. I set the tuner when the barrel was new and after developing a load. The setting was not changed since. Sunday, prior to fouling badly, it shot 150-14X at 800 yards. So, it was still grouping when clean but could not go a full Palma.

I shoot 575 and 1000 .And I very seldom find I don't need to move a very small mount daily just .001 in one direction or another. It is so simple to verify it on paper. all you need is a 100yd target that is 24''tall aim at the very bottom at 575 and it prints about 9'' up a 1000 yd it is 23 1/2 up. .001 can change any tuner I have tested from .250 to maybe one hole. most turner use a set screw or a double nut. I tried both the set screw was OK but if you tightend it after the tune changed. the double nut was very hard to get a perfect change. Tuners do far more then then change the barrel they work all vibrations in the gun. Target shooting just done a good article on tuners. Also Bostrom Gunsmithing. Larry

The fellow that is arguably the most successful short range tuner user, Gene Buckys, does not move his tuners during matches. He does a one time adjustment on a new barrel, locks them in place, and from that point tunes as one would without a tuner. Bart Sauter has been doing all right with one of Gene's tuners of late, and I understand that he is using his the same way. Used in this way, tuners broaden the node, making it easier to stay in tune throughout an event.

I shoot with Gene when he comes to Florida. Last year I got to spend a lot of time with Bart and Billy. The first year Gene was tuning a new barrel I guess because it moved it a lot in practice. He was the one that helped make the rule in moving it in a match. I think Larry Costa won a big match using a tuner. I feel in the next few years only the winners will have them. Larry
