Found this morning metal detecting.
I’m guessing 45ACP. Micrometer showed .450 diameter; dead nuts.
I’m told 45 ACP should mic at .452 inches and 45 long colt at .451 inches.
I’m guessing it changes a little after being pressed into the brass and going through the barrel.
The length is 5/8”. What caught my attention is the jacket thickness.
The lead center (end view) is 5/16” diameter (0.3125”).
I’m not a reloader. I understand how it works, but don’t know all the variables available. Other bullets I have found were either unjacketed (lead round ball) or had much thinner jacketing.
Any input appreciated.
