Personally, wouldn`t see a problem with either chambering. IMHO the fun is in the work up of loads and the shooting involved before I go hunting.
I`ve got some 7x57 stuff loaded that I want to chrony, also with the 162 ELDM`s. So Mags arn`t exclusive for anything out to 600 yrds. I`m sure there are a few 7x08 guys that would agree.
