The M7CDL/350RemMag is a looker. I had one in my hands at a local gunshop and needed a powerful lot of willpower not to blurt "I'll take it". It's just as classy in appearance as the 700CDL in 35Whelen. But with a 4" shorter tube, I liked the scaled down proportions myself and the rifle sights too. It's a slightly handier package then my 700classic/35Whelen. It would pack a simlilarly close powerful wallop if handloaded. It's a handloader's calibre as only one factory load exists - a 200 grain Remington I believe.
The M7 CDL in 350 is a modern, and classier I think, rework of the M660 Magnum concept from the 60s. I have one of those utilitarian originals and use it alot and really like it. So that kept me from laying down the $$$ on the newer and more fetching M7 - for now anyway.
