I'm surprised I don't see a thread about this. Anybody have experience reloading 9mm Inceptor ARX bullets into brass cases?
I've been casually reloading for a couple years now, and wanted to try these. Here's the load data:
https://www.inceptorammo.com/wp-con...RX355-65-9mm-Luger-65-Grains-ARX-Inceptor.pdf
My first batch was using 5.1 grains of HP-38 powder. No crimp, just barely tapered to specs. COL was 1.169", because that's what I'd been using with normal FMJ bullets; I didn't notice that Inceptor recommends 1.155". So the cartridges were a bit on the long side.
Horrible results. They fed well, but every other round with my Sig P229 failed to eject; mostly stovepipes.
With my G19 and P290RS, every single round was a stovepipe.
So... Too little powder, or too-long a COL?
I've made up a second batch with 5.4 grains of HP-38, and COL of 1.155". We'll see how these do...
