    With calipers or a micrometer at the widest diameter. You could get close with a ruler in hundredths or even 64ths.

    Harbor freight sells a decent micrometer for cheap

    get a cheap set of calipers, but judging by the weights they are probably 44 or 45 caliber. Within 45 caliber, there's technically 45ACP and 45 Colt, with a few variations on actual diameters, as some guns have bores that like a bit smaller or larger bullets. for 45 ACP it's usually .451-452 while Colt is .452- .454. Lead bullets are usually .001 larger than the jacketed bullets for the same gun.
