Great deer! You picked the right caliber for the job.......many years ago, while I was stationed in El Paso TX, I bought a Winchester model 70 in 7mm Remington Magnum.....just for that type hunting...I really enjoyed the pictures........I don't think a lot of people understand how open it is out there, and how far you can shoot.
I remember driving a 1970 Dodge superbee 440 six pack between El Paso and Alamagardo NM........flat out, WFO.......road straight as an arrow, and smooth as a baby's butt.......and the road went on forever........Spent a lot of time in Southern New Mexico........Lincoln National forest......Red River areas......
If there was ever a place for the big Magnums, your in it! Thanks for the memories!
