According to William Wixon :
"474. gun cleaner" holy sh!t! must be a BIG gun huh?

If that is for cleaning the bore of a gun, it must be a
smoothbore of some form, not a rifled bore. Either a smoothbore
muzzle-loader, or perhaps a shotgun.

It certainly does not seem correct for a rifled barrel.

Enjoy,
