.408 caliber

[Gszek]

I was recently at a garage sale and couldn’t pass up a large box of miscellaneous bullets for almost nothing. Along with a bunch calibers I normally reload there was a jar with at a quick glance looked like some 44 caliber jhp but there was no labeling. I mic’d them when I got home and they measured out at .408. They definitely look like a 40 cal pistol bullet but if I’m not mistaken, those should measure at .400.
Are they in fact 40 cal or??
Thanks in advance for any info.

I did a little looking around. 40 and 10mm both use .400 caliber bullets, but 38/40 uses .401 caliber bullets. The 40/65 used .405 caliber bullets. The 405 Winchester round used .411 bullets. Possibly one of those? Just an educated guess, I don't know much about any of the above.

401 win

jmr40, that's pretty much what came up with with a quick search. Just wondered if they could be loaded as a 40 cal. 8 thousands over seems like quite a bit though. I don't load 40's or 10mm but there are 185 of them to give ( to or trade ) somebody who does. Thanks for looking.

That’s too big for the .401 Herters Powermag, which used bullets around .402/.403”. Telling us the bullet weight might help.

Weighed in at 210 grains on my rcbs beam. definitely (or at least looks a lot like) a handgun bullet.

Are they lead bullets? Maybe someone cast them but never got around to sizing them. Just a guess.

Jacketed hollow points. look commercially made. I double checked my mic also.

Afaik, the closest for handguns would be .41mag and .41ae.

Factory seconds/blems, that should’ve been .410”. Jacketed bullets, at Midsouth, go from .400 to .410 in both pistol and rifle bullets.

401 wsl calls for a bullet in .4065 that is as close as i can think of
