First of all....300 BO is not a cartridge you go to, if you are going for match accuracy. Its an easy 2 MOA normal option.
N120 provides some good options, and all the N120 cycled and locked bolt perfectly, 0 issues. However, the CFE BLK and the 1680 did NOT cycle flawlessly, expecially the CFE BLK which failure to feed was there at least 1x with all the loads. more with the lighter load, less with the higher load. 1680 failure to feed, but not as bad as the CFE. N120? zero issues.
Why is it, that no matter if I go 223/300BO/9MM the VV powders are so dominantly supreme? I don't understand why they are so much better than anything else and make it look EZ? I don't even know much about this, and early on its standing out so clearly?
