Hello
I have a question about the minimum safe wall thickness for a Browning BLR with a muizzle brake installed.
I purchased a used Browning BLR in 300 WSM.The rifle has a pencil barrel (OD approx = .6" at muzzle). It came with a KDF muzzle brake (.6" OD, 1/2-28 Threads) already attached.
My undedrstanding is that a common rule-of-thumb states that to be safe a barrel should have a minimum of .140" wall thickness remaining after threading the barrel for the brake.
Therefore, this rifle's .05" wall thickness [ (.6 - .5)/2 = .05 ] after threading for the KDF is 64% less then the rule-of-thumb of .140".
What are your thoughts? Is the rule-of-thumb bogus? Has anyone seen first hard or heard about a BLR in .308 caliber with a muzzle brake having a problem because of wall thickness?
Thanks
