muzzle brake clearance

elkman06 · April 26, 2008, 10:13 PM

To all, I am starting on a 30/06 project. I will be installing a Harrells muzzle brake, Unfortunately, the one I was sent was apparently for a .243/6mm or such. I will either have to return or rebore it.
I have seen info out there that suggests that a properly fit m/b should have around .010 clearance on the bore size. Example .308 should come in at .318-ish to function properly.
Does anyone have experience here?

P.S. Richards' microfit stocks are the snitzz. If you can get ahold of them. Custom thumbhole for $117.

I'd just send it back and have 'em send the right one..

Sir,
Why a brake on a 3006, it is not necessary. Also, every shot you fire will result in hearing damage. No disrespect intended but it is just not needed, if the recoil bothers you go to a lighter caliber.

Well, cause I want to. I've been shooting 06's for 40 yrs. No, the recoil is not too much, It will mostly be a bench rifle, and yes..just cause I want to.
Does anyone have any info on this? Perhaps some experience with clearance using a muzzle brake? Partly it's that I like learning about non normal aspects of whatever I might be into. I don't currently have a lathe or I would do it myself. I would, however like to have the knowledge base to do it.

Across the board, 20 thousandths

308 thus is 328

You need precision tools to do it.

Thanks Mr. Alaska,
Now to see if the gunsmith is up on such.. Unfortunately he is out of town for a while.Just wish I still had a lathe or I would cut the threads and bore it myself. I've machined stuff down to .001in press fit so, just short on equipment.
