Removing brake/hider changes load data?

[thefitter]

Will adding or removing a muzzle brake or flash hider change harmonics enough to throw off an established accuracy load?

Maybe.....

Not in my experience, I have 3 rifles with muzzle brakes, 2 with grill types and one with holes drilled around it.
If you have a Consistently accurate rifle to start with.
Meaning it will place bullets in a tight group, and you do your part, it doesn’t matter weather the brake is on or off in my experience anyway.... I have herd that over tighting the cap screw on a grill brake can put pressure on the crown area and then could cause you a problem....just enough tension to hold it in place is ideal.

It definitely CAN. The only one that I have was loktited and screwed on until it just touched. It did not affect the accuracy. I am quite sure that torquing one down would alter the harmonics.

fitter,
In my limited experience it can make a difference in some rifles, My 6xc it makes no difference @ all I am not sure on my 6*284, however on my 338-378 wby magnum which groups consitantly 1/2" will shoot several inches poi differently with the break vs. without the brake.

Thanks. I have an AAC hider/suppressor adapter that I took off tonight. I just wanted to get a heads up what to expect next weekend.

Man that thing was FULL of crud!!

It can...

1st 3 shots with Badger Ordnance Thruster brake installed:

2nd 3 shots...

3rd group (yes, I shanked that one big time)...

4th, with brake removed:

That was typical of my experience with trying to remove the brake for some casual F/Open shooting. Maybe I could have tuned the load for 'un-braked' use, but it shot so good with the brake on I just left it as is - until I finally sold it.

Heres what iv experienced with brakes left on, and then removed. Little change and what change there was,was Probably shooter error.

What is your rifle set up? Thanks

My set up is nothing fancy: a Caldwell rock front rest, a Deluxe Protektor Rear Bag both filled with Zircon sand. zeiss scope, Rifle is trg-22

Could be that without the break, recoil differences is effecting the POI.
Tuning may be just a tad off, because of the change in mass on the front of the barrel. If it is a real good load, it should be too much of a difference.

Ummm... TRG-22 and Zeiss nothing special?
