Re: Factory load chrono numbers for the .300 RUM
I bought a box of factory remington 180 core lock ultra's for my 300 when I first built it so that I could shoot it. They cronoed at about 3350 but only shot about a 1.5 inch group. 3250 shoots much better out of my barrel, although now that I have changed powder from rl 22 to h 1000 my velocity is up to about 3325 with very good accuracy.
