Re: Baffled?

Inside diameter of the brake? They are supposed to be a certain amount larger than the bore size. But....that still doesn't explain why the 308 shoots thru it just fine...hmmm

Re: Baffled?

It depends on how your smith is checking the bore to threads. Some barrels are like a jump rope inside. So while they are turned on centers in the middle of the barrel the bore is way off. With a barrel such as this the threads could be within a few thou to the bore but the bore is actually pointing in a different direction. I recently chambered a barrel and dialed in roughly a 1" section of the bore for straightness where the pilot of the reamer was to finish cutting the chamber. The crown end of the barrel was off .134" at 22" long and it was turned on centers at 27" long. A barrel like that could easily experience a bullet strike over the length of a silencer.

slow it down below 3100, you're likely disrupting the flight at the crown with turbulence. i switched to H1000 and use @ 1gr less per same velocity as Retumbo.

if you need more speed than that get a 30-378 and a longer pipe.
