IIRC the Winchester Legendary Frontiersman was made in 1979, a completely safe load in my rifle, accurate, more than easy case extraction, and have never came close to loosening primer pockets, I bought 250 sticks of Winchester brass in a white box years ago, am still on the first 100 cases and believe they're on their third loading.
Something about sitting in a chair out in your pasture and ringing 1 and 200 yard steel shooting off a crossed leg with a lever action rifle and Lyman receiver peep.
Edit to say, my bullets are sized at 380 inch, also, with the 38-55 having thinner brass [more case capacity], pressures will be lower across the board when loading high performance ammo, and lastly, with my rifle having a 15 twist, shooting the heavies is a piece of cake.
