So after hiking 6 miles round trip with my semi 30-06, I was extremely sore. That Remington gets HEAVY when using the standard sling... Anybody have experience with the Boonie Packer Sling made in Salem? http://www.redi-mag.com/index.php?l=product_detail&p=14 I am hoping to find a sling that will distribute the 10lbs better. Thank you for any advice you an provide.
