Is there a general rule of thumb about whether muzzle brakes move the point of impact relative to no brake. I ask, because I would like to use the same rifle for tactical / steel plate shooting where I could use a brake and mid range or long range NRA shooting where brakes are not allowed. I don't want to have to rezero the scope and I like the scope always to be able to return to zero withour adding or subtracting. I will be shooting both soon and I am hoping that there will not be any change in impact.

Re: Muzzle Brakes and Point of Impact Change
If i remove my Badger FTE my impact is 5 MOA higher @ 100yds .

That's about right.

Re: Muzzle Brakes and Point of Impact Change
No general rule in firearms short of they go bang... That being said i get 1mil lower impact with muzzle brake on my Tikka. I think muzzle brake acts also as a tuner (.22lr comp. rifles) and changes the way barrel whips when attached.

Re: Muzzle Brakes and Point of Impact Change
I also get about 1-2 moa change in POI when I take my brake off. I've noticed that it depends on the load as well.

Re: Muzzle Brakes and Point of Impact Change
The general rule is - test your rifle with and without the brake to see what your rifle and brake do.
I had Brand B give me a 6 MOA elevation shift from unbraked and Brand R give me basically none.
This is not one of those questions you can get an answer for over the Internet. I take that back - you can get lots of answers; what is in question is how do they apply to your rifle.
Only you can answer that.

Re: Muzzle Brakes and Point of Impact Change
No general rule, every rifle, muzzle break and load is different.

Re: Muzzle Brakes and Point of Impact Change
I have a theory about muzzle brakes that I havent had time to test...
Theory is that any "shift" is partially due to the muzzle moving latterally from blast deflection. What got me thinking about this was I thinking about bipod hop a while back. I shoot mostly in sand and there is a very clear blast pattern in the sand after a range session. You can see where the blast goes and the effect it has, and something was burnt in my brain from my flying days...
When you redirect blast (regardless of its source) the object that changes it path will be pushed in an opposing direction. When you consider all of the different movements during an autos firing cycle its hard not to ask whether or not the brake (if not perfectly compensated for the load) can have a negative effect. After all...high speed gasses exit the brake <span style="text-decoration: underline">in front of the round</span> latterally while a round is still travelling through the bore.
It's almost a no-brainer.

at 100y adding my brake, raised my POI 4 or 5in i think...

My .308 with out the brake is 1 moa high at 100yds. Test your rifle and write it down.

Re: Muzzle Brakes and Point of Impact Change
I removed my BO brake for f-class over the weekend and the results were .7 mil high and .2 right at 600 yards.

Re: Muzzle Brakes and Point of Impact Change
I took mine off for F-Class too. I didn't have any change. It's a AI QD brake. Shot the dot drill and tested out to 1100 yd and my DOPE was the same. However, you need to shoot it to find out.

Re: Muzzle Brakes and Point of Impact Change
5 MOA at 100 yards? For a brake being taken off? Am I the only one, or does that sound, well, like its time to get serious about your threading.

I think it does change the way the barrel whips. This effect is not consistent with all barrels and seems to be at a minimum with stiffer barrels. Usually the change is consistent so you can just dial the mils/moa to compensate for the change.
