Absolutely beautiful buck and rifle both!

The 7-08 is an excellent cartridge. Not as popular as it should be, but it's basically a modernized version of the classic 7X57. Loaded to the same pressures in the same length barrels and firing the same weight of bullets there is virtually no difference at all between the 2.
I have made many 7-08s and also quite a few 7X57s. I owned and used a 7X57 for many years myself and killed game from coyotes to bull elk with it and never saw a thing to complain about.
That deer will be one to be remembered by your kids and grand kids, and when you grand kids have kids that rifle will still be an outstanding tool for the field anywhere it's taken.
