I am not done load testing, but here's some information that Bryan Litz passed to me when I was asking for a starting point with the 180gr 7mm "Hybrid" bullet. Official designation is the "XDR" I belive.
I realize this isn't a complete range report by any means, it's just starting points for other guys that got some of these bullets on the sale last month.
Bryan's Test Results:
G1 = 0.674
G7 = 0.345
He suggested loading them on a 0.015" jump, which happened to work out well for me as well.
I haven't finished load testing my 7mm-270 (that caliber is a story in itself) so I will refrain from any further info that I haven't tested enough to be comfortable with. I only have enough data to know what my next steps are going to be in the testing. I will update as I work through it. I would expect end results before June 10th, since I have to be at TVP on the 12th, so that's the drop dead date.
Cheers
