Four years as M-60A1 driver/loader/gunner/commander.
I agree. Although, depending on type of grenade, I would say there was a pretty good chance the inside of the barrel would be damaged enough to make firing 105 rounds a bit dicey. Pitting of the rifling...perhaps a crack.
That was my thought. A tank ammo round is made to explode so as to shoot the force in a single direction (out the barrel) a grenade is made to explode outward spraying the deadly shrapnel or phosphorus etc. in all directions which would definitely stress the barrel way more than a tank round.
I definitely would not want to be the gunner who put the next round through it after such an episode. And I know for sure I would not want to stand near the barrel when the next round was fired!
A crack in the barrel... isn’t that the very definition of a Bad Day for a typical loader?
