Taylorce,
I had a 1:8 270 WCF built and used it last year on elk, antelope, and deer. 155gr Barnes LRX with Rel 26 @ 3000fps. I really like this combo.
If you are going to put a new barrel on, definitely twist it fast! I have looked at the fast twist 270 cartridges, but have never been able to bring myself to jumping in the deep end so to speak.
If I was to jump in, I would choose a 6.8 Western. Hodgdon lists most load in the 3000fps range with 150gr bullets, which is ballpark to what I am getting with my plain 270 WCF. The WSM holds more powder, so if that is important to you.
Any way you spin it, the 270 caliber is probably never going to get the competition industry support (top of line brass) like Creedmoor's, PRC's etc. No matter how much of a 270 looney I am.
Those are my thoughts anyhow...
