The 300 Win Mag is an inherently accurate round and was commonly used for 1000 yard Wimbledon Cup matches. You also have several quality brass options available as well as factory ammo in a pinch.
Between the 300 Win Mag and the 300 WSM, I would go 300 Win Mag and never look back.

Congratulations to your son on his mule deer buck. It's been a while since you posted a picture of Jeff but he sure grew up!
Best wishes to you on your shoulder surgery recovery.
