Definitely going to pick some of these up. 152g seems a bit heavy for a 280ai copper bullet but ill give it a go.
Which is a little strange, I mean I could see them using an average velocity to calculate the G1 BC of the component bullets but it still wouldn't make sense that the 7-RUM factory load BC is lower than the component bullet G1 BC, because there isn't anything that'll skew the results *above* that. Unless they have some .284-378 Weatherby in the lab or something.Component bullets are listed as:
139 LRX .470
145 LRX .486
I had some 145 LRX’s loaded at 3,013 fps. Zeroed at 300, calculator said dial 8.2 MOA for 600, dialed it and it was correct. So I’m guessing that .486 is pretty close.Component bullets are listed as:
139 LRX .470
145 LRX .486
