IMHO, this is like asking which flavor of apple is better. I own, and have killed with both. I absolutely LOVE both. Mostly because of the rifles they are in. Both rifles are absolutely tack drivers, capable of producing one hole groups, ifin' all goes well (ie I shoot like I should). I reload for my WSM, and it LOVES the 140 NAB's. I shoot factory for my WCF, and it LOVES the 140 NAB's.

Give me one gun to grab, for anything and I will feel 100% confident with either one.
