Barrel tuner results

[Frogman77]

Wanted to share some results with the kinetic security solutions tuner I picked up a few months ago. I'll be honest, at first I was a bit skeptical but it's pretty apparent that the tuner definitely does "something". In this particular case I was able to find a setting that yielded some excellent results.

Normally I do seating depth tests to fine tune my load. This time I just used the tuner.

Rifle specs:
Patriot Valley Arms 300 WSM
Big Horn TL3 long action
26" PVA button rifled light Palma contour barrel 1:7 twist
KSS hunter tuner
PVA shockwave muzzle brake
250gr hornady ATips 2615fps

Two shot groups per tuner setting until I found two touching and then shots opened up again. Picked the setting between and fired a 5 shot group. Went out the day after and shot another 3 round group just to confirm.

Planning on taking it out to distance and see how it does, but so far I'm fairly impressed with the process.

Thanks again to both Aaron Hipp and Josh Kunz for the pointers. Looking forward to seeing how it does on moose this fall.

Yes tuners make it easy. I have a EC on a 300win, made a believer.

Interesting what holds it on your barrel?

Barrel Tuners, we came full circle.
I love them. Browning/Winchester introduced the BOSS back in the early 90's. I bought every caliber.
I used to get attacked on forums by bringing the subject up. Barrel harmonics, Engineers, analyzed them, modelled them, shooters attacked them. Now they embrace them.
A tuner can make a factory round shoot great in your rifle. It Can make a custom load shoot lights out.
If the price comes down, I will consider adding them to the rifles that don't have them,

It took me a while to figure out the boss system way back when and the muzzle brake didn't make any friends but it was hard to argue it's effect

Yep, muzzle brake did not help for the on-lookers. For my favorite calibers, I did buy the non-brake BOSS

As a machinist, it is a very simple design that solves the problem of using a can or your own choice of muzzle device.

Man you are good in that you can rely on 2 shots as sufficient samples! I, perhaps foolishly, keep questioning and trying to perfect loads if I can't consistently put 5 in the same ragged hole. But if you keep returning to range and shoot 3 touching as the first 3, that's even better.

Interesting to see this tuner thing evolve. Of course Browning has had the BOSS system for over a decade but I rarely see them in people's hands. I haven't even seen them on recent models. I always wondered how well they work. Great concept if they work. I almost tried one of those rubber grommet type tuners about 10 years ago.

They work. Why the boss never caught on IDK.

You were never 'tuning' a load with seating. You were merely optimizing bullet-bore interface.
You swap primers to find what likes your particular striking.
You cannot replace these functions with a tuner.

Load tuning is done with powder and starting pressure (neck tension).
Barrel tuning is done with your tuner.

A fully tuned gun has the prerequisite seating and primers worked out, plus best powder load, plus best barrel tune.
All together
I still believe BOSS is the best system.

My Opinion:
1. The loudness, people were not used to brakes yet and Browing and many people did not know you had a non-brake option.
2. People never took the time to understand it and work with it.

One of the great things I liked about the BOSS is it gave you starting points of various factory loads in each rifle/caliber. Different for Browning vs. Win M70. I used these starting points tuning my barrel with my loads. I did not find out about BOSS till Winchester line ws discontinued, and I manage to get most calibers. Missing 2-3, but no longer acquiring any new ones.

Awesome. I've also recently started playing with tuners and haven't yet got them figured out but definitely enjoying playing.

I loaded till I found a load that gave me sub 3 sd's then used a tuner. The issue was the load shot ugly. .8-1.2 moa. Then I played with the tuner.

Here is before tuner; 100, 300 and 575

Then after tuning
