Couple/few things.
So, a bucket list gun is available. . . .
This right here answers the question - buy it!
I did! Like I said before, my gun regrets are the ones that got away.
Plenty of experience with 7mm Weatherby Magnum. Never wanted for more. Not too far above the 270.
My main reason for picking the 270 over the 7 is because it was the first. In the field I would use them interchangeably. Both are outstanding.
My 24" barreled mkV270 wthby mag sporter likes 150 gr Hornady sp and 7828 with fed 215 loaded to 3150fps.2 of my biggest whitetail bucks and 3 antelope...mb
Everyone seems to point at 7828, gonna need some.
I have a left hand German Mark V in 270wby. It shoots best with Barnes bullets, as do most of my older Weatherbys.

I suspect that Barnes bullets like a bit of jump and weatherbys accommodate that. (?) A 129LRX going faster than Superman does hold some appeal.
