Have a pre-war Deluxe Model 71 in 450 Fuller with a 22 inch bbl. I guess you could split the difference with a 21 inch barrel.
Weight also is a factor. I also have an earlier Marlin 45-70 with a 22 inch bbl. If you are in the alders with a wounded or angry grizzly,
its accurate repeat shots that one may need. Its personal preference and confidence in the individual weapon that counts.
The Wyoming guide in 2018- NW of Yellowstone near the Wind River range that was killed by a grizzly probably would choose differently
if he had another opportunity. In Alaska, what you are carrying quickly can become one's "bear rifle". Choose wisely as you never
know what will show up at the skinning pile, or around the next spruce-birch bend in the trail.
