Barnes TSX

[USMCDM24]

I'm having a hard time getting my hands on the new edition of the Barnes reloading manual. I'm looking for the load data for a 140 gr TSX (non-tipped) with either H4831 or RL19. Anybody have some info?

:?: BTW, when can we expect a .277 E-tip to appease the granola-eating, tree-hugging condor freaks here in CA?

What one 270 Win, 270 WSM, or 270 WBY Mag???

JJ is right. Chambering might help a little!

I am thinking 7mm rem mag....am I right? :?:

Sorry guys, .270 Win.
