You might want to consider a muzzle brake for that.

and both ear plugs and muffs.
We all have our reasons for using or not using something. I have been using Win M70 BOSS since it was available. I like the brake but have acquired the non-brake option for every BOSS rifle I own.
I put brakes on most of my other rifles. Are they loud? Yes! But I use double ear protection.
If I had the funds, I would install a tuner/brake on every other rifle I own. But that is me! I don't compete. I shoot for pleasure and I hunt when the oportunity comes.
Its GREAT TO HAVE CHOICES!
Yes, the EC tuner brake is already installed and range tested, but I have not played around with the tuner part yet. I also have a suppressor for it.You might want to consider a muzzle brake for that.

Went our yesterday ,did the same as before 6 each with the 3 different powder charges and seating lengths ,ditto, same stuff, first 3 for accuracy about 3/4 each", next 3 of each through the chronograph, all 3 loads being different in lengths an powder charge were the same a ragged 1 hole, I mean that's wonderful. one can't go around with a magneto speed attached to your barrel all the time. I bought some leaded tape and will try that Wednesday, it's snowing like a BITCH here already 8" new stuff in 2 hours range is closed Monday and Tuesday, Sunday is my wife's day off so that's a no brainer for me to leave to the range. I was thinking though, if it is the weight part then hopefully the tape will show something, if it is the Magneto Speed then I wander if it is because it being a muzzle break that is cut into the barrel with side ports when the gases reach the end of the barrel they can shoot down hit the magneto speed and change the dynamics of rotation ,just guessing, TOO DAMNED OLD TO WORRY ABOUT THIS S--T just wish it would shoot like it does with the Magneto Speed on!

It is a system, however, weight seems to be able to "adjust" harmonics (origial BOSS idea). this explains it a little better than I can
You want the bullet to exit when the muzzle is at a certain position. Chris Long wrote about it long ago.
You can Adjust the load, or weight on barrel, or a combination.
A very good friend designed the BOSS system. We tuned Browinging BARs in 270,30/06, and 7 mag to shoot sub-half-inch groups, often in the 3/8" area. We stuck to a particular brand and weight of ammo. A Bolts in the same calibers shot slightly smaller groups, tuned easier/quicker.
I have not tried the approach of adjusting the tuner for a particular load I wanted to shoot, but instead worked up the load with the tuner screwed all the way to the rear, then started adjusting the tuner. The result of this method took a 1/4" groups, down into the zero's and 1's.
This method was repeated with the Mike Ezel tuner, RASS tuner/brake, and Harrell's tuner brake.
It is to be noted that after initial load development, within 1 revolution of the tuner, there may be 3-5 settings that will shoot a single bug hole, the trick is to find the setting that has a spread of 4 numbers or more that shoot that bug hole. This whole procedure happens quickly, not some long drawn-out affair. The load is then verified at 300 yards verified where sub 5/8" groups are plentiful and often 1/4"-3/8" groups are real world.
Winning in the Wind, Keith Glascock, is one heck of an F class shooter, national standing. His videos on barrel cleaning are the best I have ever seen.
With Keith's references to tuners, remember, he shoots the same 284 win or variant, the same barrel maker, same reamer used on all barrels. So, he has a constant in variables where he can tune barrels based on a long history of what works.
So, for hunters trying to improve their accuracy way beyond 1/2" groups, I feel that a tuner will help them tremendously. A guy has to have the patience to develop his load, then tune, and this is not for everyone.
Other than use working with the Brownings with factory ammo, I have no experience in using a tuner with choosing any ole load and then making the tuner take the load down in group size. This same would apply today with a PRS shooter or hunter that uses factory ammo to hunt with, trying to achieve the best groups he can get. When tuning the Browning BARs, the most we ever used on finding a "node" was around 40 rounds or less. A-bolts with the BOSS system took less tuning on the tuner, and I attribute that to the Gas block and three-piece stock on the BAR.
For a guy on a budget, the Harrells tuner/brake at $95 works like a champ.
A friend told me that a can company was making tuners to be used with their cans.
The OP was trying to find a way to duplicate the groups that his rifle shot with the Magneto Speed attached. A simple solution may be to weigh the magneto speed, then duplicate that exact weight with the stick-on wheel weights that they balance tires with. The position of the wheel weights may prove to be critical, and the whole affair may prove to be a waste of time due to positioning.

Sorry for your troubles. This is one of the reasons I opted for the LR over the MS. Good luck!

What we need is a method to measure what the muzzle is doing, and it would seem simple to do that.
Well, I tried it one time with a laser mic, optical trigger, and DAS sampling firmware/software.
The object was to create a 'tuning box' to place the muzzle in, non-contact, and fire through.
But my attempt was a total failure..
Too much going on, too fast. No way to isolate or resolve actual meaning.
This could be done. We've walked on the moon. But OMG $$$$$$$$

Supper fast camera (to play real slow motion)? You could attach accelerometers, but any time you atch something you change the harmonics
@VinceMule have you tried the Harrel's tactical on a hunting rifle? Or has anyone else? Can't beat that price

4 sluts on top of barrel near muzzle. Where can I get one of these ?
