9mm LRN?

[Viper22]

Awhile back I was handed some projectiles, of what I assume to be 9mm. They weigh 124 grains and measure at .356-.357”. As compared to 115 grain FMJ at .355” and 115 grain Berry’s at .356”.

I’m wondering if these are 9mm?

Yes

In case you want an echo... yes!

Cast bullets generally run a 1/1000th inch over the standard jacketed diameter. Even if the box says 115gr JHP .355", you may find the bullets are .356" or other dimension. Oftentimes they aren't exact as marked. Bullets marked .311" may be .310" etc.
Some casters may offer custom-sized bullets, so you may find bullets several thousandths over/under-size.

Incidentally, I heard that Mr. Carroll died of lead poisoning, but I can't swear to this (just hearsay...).

Thanks for the info. I was fairly sure, but when it comes to reloading, I wanted to be 100%.

alloy temp and composition can change it a few thou also along with sitting around for years alloy does things?

Carroll Bullets always shot good for me! Appears to be 9MM, enjoy!

Loaded a test batch last night using Bullseye powder, CCI primers, and the 124gr Carroll bullets. Held OAL 1.100 +/- 0.003. Loaded 10 rounds of each charge at 0.2gr increments from 3.4 to 4.0gr. Bullseye metered very consistently out of a Lyman powder measure. Hoping to get out this week to test fire.

Please report back with target pictures!

In the earlier days (that is, when Carroll was still operating), I often used their 225g LTC .45 bullet with good results.
These days, I think coated is the way to go, even though I haven't adopted this process with my own casting endeavors. To be honest, I haven't been doing much casting anymore, as I find Norm's product and pricing make it hard to justify lighting the Coleman Stove. There are plenty of sources for economical coated bullets these days. Yes, it's still a good skill to know, but it is rather labor intensive.

Had FTE issues on 3.4 gr, but great accuracy - compared to factory loaded Blaser 115gr FMJ.

3.6 gr functioned well. 3.8 & 4.0 gr both had FTE issues, however likely more of an issue with me limp wristing. Makes me wonder if I did the same with 3.4gr.

I'll have to load up another test batch and give it another run.
