If you're seeing throat erosion with a cartridge that operates at ~50,000psi working pressure, I'd be interested to see some quantifiable measurements before and at different round counts.
I haven't seen anything like this with my 16" barrel that I've had since 2009. Les Baer has a barrel they claim is shooting sub-1/2 MOA after 20,000rds.
