lostthway,
www.gun-tests.com is where the info is.
look in Tools and Techniques
then Ammunition
then read these two articles:
Premium rifle bullets
300 Win Mag winners

Read them both because they have different info.
One liked the x bullet best and the other the Swift a frame.
They compare them to the fail safe and the partition and several other common bullet types including a couple plain jane factory loads which tested very well.
Good info!
