I like them. If I could turn time back a bit, I would have got one instead of the 300RUM. With the long cases of the RUM, Weatherby, and Win Mag, it can make it difficult to make an accurate load. And to be honest, it would have suited my hunting perposes better than a 300RUM. As far as technology, the shorter fatter version is more efficent at making energy than a long column of powder. Just makes sense, to have a beltless, fatter magnum for those who don't have to have the speed of a Weatherby, RUM, but can still chuck a big peice of lead/copper 500 yards with some good energy numbers.
