Log:
I saw where you had a 450 Alaskan on a M-71, I am assuming-marked H. Johnson on the barrel. Some of those were
marked on the barrel: JKR for Johnson Kenai Rifles, the
name of his shop in SE Alaska during the early fifties.
I have a 450 Alaskan and Fuller that came out of Alaska.
Both are long tang early Model 71s. Johnson also liked to use late smokeless 1886 Winchesters for the 450 conversion.H. Johnson was a WWII Marine.
Bill Fuller was Johnson's riflesmith, making the reamers. His 450 Fuller has a slightly easier shoulder for chambering and feeding-than the Alaskan. Alaskan dies will still handload OK. I have kil;led deer and moose with the 348 and 348 Ackley. With good Hawk or Alaska Bullet Works.
bullets- bonded core-you can push the 348 Ackley to 35 Whelen velocities. The 450 is good for Alaska as you never know what might be around the next black spruce-waiting at the gut pile.
