AckleyGuy & QH,
Alot of smith's including myself put brakes on with a little bit of lock tight. Several brakes like OPS Inc or Badger "time" up with the barrel shoulder and threads and are not meant to be screwed on and off. If you do the threads will stretch and the brakes can "over" time.
I am not saying your cleaning method is wrong, but I have shot, cleaned, and built and rebuilt hundreds of braked rifles that were cleaned with the brake loctited permanently in place with no lose of accuracy.
Back to the problem, if you have a small torch you can lightly heat the brake to soften the loctite to remove the brake.
PS If brakes are properly installed they do not mess up barrel harmonics, change POI a little but they should not change accuracy.
OK guys here is what happened today the 180 Accubonds and Retumbo.... stay at 2 -2.5 @ 100. the same bullet and 8700....a bit better but not much...OK, back home to pull my hair out...then....... clean the livin hell out of the barrel...shooters choice...JB...Sweets.....Ok now I was not shooting moly in this gun but figured I am going to try it (alot of my .308 bullets a already coated)....Load some 190 Sierra MK,s..over a few diff charges of Retumbo and.... yep looks like there is a .5 inch for 3 @ 100.... well time has taught me not to get to exicted over 1 of anything(well most things [img]images/icons/grin.gif[/img] ) back home...reload 5 more and 97.5 grs Retumbo fed 215 Mag match, 190 Sierra, and .62 for 5 @ 100 with low shot to shot devaition < 12 F/sec) and a avg muzzle velocity of 3273 @ 15 ft. Now I can rest a bit better better...And the wife has begun to speak to me again ( is this a good thing? [img]images/icons/grin.gif[/img] ) And the dog even has come back into my reloading room...for awhile there I think she thought I renamed her too.... well you can imagine the words she heard about my gun, the folks at Remington Etc., etc [img]images/icons/tongue.gif[/img] . Looks like I have something now...hmmm what the hell are those?? 185 Berger VLD's on my bench...Looks like we have to go back to the range again tommorrow......Thanks agin guys for all you input and help
Go to disagree that a brake will not effect harmonics.
How can a brake not effect harmonics? Defies the laws of physics for it not to. You are changing both length and weight of the barrel, two critical items of barrel harmonics.
The original idea for the Boss system came when the factory discovered removing as much as 1/8-1/4 of an inch off a barrel took it from a non shooter to a shooter by simply changing the barrel harmonics.
Anytime you go hanging a 1-2 oz piece of metal on the end of the barrel it will effect harmonics.
I have shot ladders with my light gun with brake on and off and I can tell you there is a marked difference in the group clusters. I proved it repeatedly testing with and without brakes at longer distances also. I tuned it for the brake on and only shot it in one match without the brake and after I had worked up a load for without the brake.
That is why this time I rebarrelled the gun the gun without a brake.
I am agreeing with Bounty Hunter. There is no way a muzzle brake doesn't change the harmonics. The proof is that very few rifles shoot to the same point of impact with or without the brake. Some might be less than others, but most will move. As for the other issue,anyone who has had a brake installed and the crown came back messed up needs to find a new smith that knows how to instal them right.
Become sheep and the wolves will eat you!
Okay, I guess I wasn't very clear in my last post.
I agree that they do change harmonics in the fact that it can and most likely does change POI from brake on or brake off.
I do not believe that they affect accuracy. I have built to many rifles for competition shooters that shoot with brakes in tactical matches and without in F class and have had zero reports of the rifle changing in accuracy (group size) with or without the brake.
My point was a brake will not affect accuracy if properly installed. Ackley Guy definietly has a problem somewhere. It might be with the brake, crown, bases, rings, scope, or action screws. All of these should be checked before you start throwing more variables in the picture by changing loads.
brakes affecting accuracy? well yes an no.. physicaly or even mechanicaly a well in stalled brake should not affect rifle accuray ie. group size one way or the other. If the brake is incorporated into a barrel weight system aka Boss then yes you will change the harmonics of the barrel when you alter the position of the weight.
The biggest effect a break can have on accuracy is that there is less felt recoil which may make the shooter able to shoot a hard recoiling rifle more accurately, altenatively due to increased muzzle blast the shooter may shoot a lighter recoiling rifle not as well with a brake fitted, we all have our individual recoil and noise sensetivity levels.
Now if we use a moderator then we have the best of both worlds, recoil and sound are reduced.
I once had a rifle fitted with a boss system, it was the biggest pain in the butt i ever saw, to expect a barrel weight make a cheap barrel shoot consistently is asking too much, far better to start with a trued reciever, properly bedded in to a quality stock and a good quality barrel be fitted. then you know you have an accurate starting point, there after if you put a brake on it or not it shouldn't get any less or more accurate. and besides, a custome barrel is fareasier to clean than a cheapo factory thing..
