what's the difference

[tsmaxx47]

i'm comparing the remington 300 ultra mag, the 300 winchester mag, and the 300 weatherby mag. what is the primary difference ballistically between those three rounds?

Ultra mag is fastest, weatherby next then the winchester. Remington does load a ultra mag that's about the same as an 06

I second dun. IMO a win mag is the way to go. Your bullet selection is by far greater and cheaper and easer to come buy. That's just the way I look at it. Sometimes I will trade performance for accessibility.
