My family and I are going on our first Mule deer hunt. I have a Winchester Model 70 .338 that I love and have used on Moose and a Whitetail. This is my first ever Mule deer hunt. We are hunting late second season in GMU's 52, 53, 62, 63, 65 & 521. This is through Rugged Rack Outfitters. Would the .338 win mag be great or would it be wise to get more of a medium caliber like a 6.5 or 30.06? Also has anyone had any experience with this outfitter? I have a really good friend who has been with them and had great success and a great time with them, so they were highly reccomended. Thank you
