Apples? Meet Oranges.
Semi auto or revolver?
Both supersonic. 158gr 357 vs 155gr 10 (.40 caliber). About the same velocity.
10mm 180 standard bullet. Heavier bullet. Perhaps more knockdown power
357 maybe 180 gr. Max though 158 grain is standard
357 probably better penetration because it’s smaller.
Truth be told I wouldn’t want to get hit by either.
I would take either deer hunting though I find revolvers more reliable.
Many semi autos are lighter and easier to carry.
Generally speaking a heavier bullet gives more penetration than a lighter bullet.
Generally speaking a faster bullet gives more penetration than a lighter bullet.
