I've fired about 100 ea. .45-70 cartridges, both factory and hi-octane hand-loads from my new Kodiak MK IV
Double made by Pedersoli of Italy. She locks up like a bank vault, and I cock both barrels for a quick second shot. No problems. Recoil is less than a Garand. Over 10 pounds of good Italian steel make for a strong shooter that will, hopefully be still shooting long after I've passed it on.
