Do Muzzle Brakes Effect Accuracy?

[NorthernSniper]

I have had this type of experience with Stoeger the Sako distributor for Canada, the main difference being that if the rifle will not shoot 1" with factory ammo they replace it no questions asked. I have had 2 308 WarBirds replaced the last one shot 6-8" with the brake on and 1 3/4" with it off. I don't know what happened to Sako's barrel's but my friends 338 Hunter 75 is shooting 6" groups at 100yds now, my sons 300WSM tikka has a mile of free bore and will only shoot 1 1/4" with 200gr Accubonds nothing else. Stoeger replaced both WarBirds no questions asked even though I had the brake installed, maybe it had something to do with my e-mailing Sako in Finnland to bitch! [img]images/icons/smile.gif[/img]
