im not very good in firearm knowledge and my neighbors son asked me a ?
using a ruler how do you explain to a kid how they get calibers for firearms. ie. 9mm 45 cal 50 cal??? the easiest explination would be greatly appreciated
I notice someone said 9mm is 9mm, it is .356 a .380 is also .356. A .38 and .357 are .357, so a 9mm bullet (not cartridge) can be loaded in a .38 or .357 case and will work just fine.
