According to 6mmbr.com maximum OAL is 2.4409
Previously I determined that my OAL was 2.345
I replaced my barrel nut & recoil lug from Northland shooting supply.
the recoil lug is twice as thick as the factory lug
I have reset my head space with a go gauge. I inserted the gauge, closed the bolt & screwed the action onto the barrel until the chamber bottomed out with the gauge.
I put scotch tape on the base of my go gauge adding 0.002 a created a no go gauge.
My bolt would not close on the no go
Repeated testing resulted in the go gauge continually chambering & the no go NOT chambering. Exactly as I'd want.
The action & the chamber are now farther apart because of the thicker recoil lug.
Using the Hornady OAL guage & modified 6mm br case I an continually getting an OAL measurement of 2.244.
The previously loaded rounds with the OAL of 2.345 consistently chamber.
This is a major change in OAL. I do not understand why this is so. It seems as if I've missed something
Any ideas?
