Tim,
I think it is a better cartridge than the 7mm WSM because it is smaller in diameter and has some taper to the body. I considered one myself in a 700 bdl and think it would work best with a 24" barrel because it has a little less case capacity than the 7 wsm..

would be a good place to look ...there is a lot of feedback on it there.
