*Slugs. At least here on AGN . The term "bullets" can make some uneducated people go into Karen mode.
Diameter change just causes ideal or non-ideal engagement with the rifling, and will also cause more or less friction. It should not impact spin rate unless the diameter is WAY out of tolerance.

Check for a burr on the muzzle crown. If the crown looks good... Oftentimes we "slug" the barrel to determine optimal size of the bore, and with that information use a sizing die to resize the slugs.
