Just got a 20 inch 338 Lapua barrel from an unfired 2013 AX338. The barrel is black with M18/1.5 thread.
I am limited to 300 caliber because of the range limitation and ordered a 300 norma barrel. This has to go.
When running 285gr bullets, 20 inch should be able to generate 2650 ish fps vs 2800 fps through a 26 inch tube. In my BC calculator, using 285 ELD-M at 2650 fps 2100 ft altitude, it can still be super sonic at 1 Mile with ~800 ft-lb energy vs ~950 ft-lb from 26 inch - that is impressive performance. And you get a much handier setup.
