Re: New barrel, 270WBY or 7mm STW
If you liked your 270, why not rechamber for it again.
I have a 7 STW and am a big fan of that caliber. If you are looking at longer shots on elk size game, I would not go smaller than a 7mm. Just my opinion.
But you already have a 300 Weatherby , so you got that covered.
Ballistically,I like the 7mm over the 270.
