Well, into my 50's I pounded the Northern Rockies carrying a 10 1/2 lb. Shiloh Sharps chambered for the 45-90. These days, if I still hunted, it would probably be either my 1903 or 1908 Mannlicher/Schoenauer. Who knows....heck, I'd probably use one of my double rifles. I have a Merkel in 8 X 60R Magnum.
