Great old caliber. I shoot a rebarrled military action Krag. Don't load it to hot, use 45 grains of IMR 4350, with 150 - 165 grain bullets. That is enough for me, deer shot with it go down. Mostly use cast 200 grain bullets with 4198 or 4579 powder, just fun to shoot. The light cast loads allow lots of practice. Not knocking the magnums, but for fun I'll take my Krag. Your Ruger should allow much more freedom in the way of load development.
