Not too shabby.Took a little longer than usual as I first received a light profile .300 BLK barrel, but Jennie got everything straightened out and squared away promptly.
Both barrels seemed to be of a quality manufacture, and each came with a deep black oxide finish and slathered in heavy oil. I was delighted that the hard steel tools used to mock everything up did not scratch or mar the finish on the barrel nut at all. I’m waiting on more parts to complete the build up, so I cannot comment on down-range precision at this point. However, during mock-up I did learn that a .313” Badger Ordinance recoil lug is just a few ten-thousandths too wide to allow for proper head spacing. The factory take off recoil lug fit with room to spare, so a .250” tapered lug is now on the way and I anticipate that it will serve the barrel well.
Just about the only thing that I would change if I had the opportunity is that the throat of the chamber is cut rather conservatively. According to my Stoney Point OAL gauge a 190 grain Nosler Accubond LR hits the lands at 2.975”, a 208 AMAX is 3.010”, a 168 Balistic Tip touches at 2.935” and even a conservative 168 grain Custom Competition will need 2.870” to touch. This isn’t a deal breaker for me, as obviously this isn’t a custom chambering and the VERY reasonable price reflects that, but it’s something many seasoned shooters would be curious about so I included that info.
What really counts is how the barrel shoots, and shortly after I get everything torqued up, I’ll begin load development and update the review accordingly.
