I like it !
I'm from Indiana and we started with slug guns and MLs only, then opened up to PCRs, and now finally rifles. I honestly think I was the first person to discover the .458 Socom met the PCR criteria. I kept it a secret until a few weeks the cat was out of the bag as I wasn't the only one that figured it out. In the end, I ended up building one for a prominent member of the IN DNR. This was before the .450 BM existed, which became popular later.
After I was bored with the SOCOM, I had a .358 Hoosier built (based off .358 win) on a Remington Model 7 action. We had a 1.8" case length restriction and the Hoosier worked wonderfully.
Anyways, good on you for thinking about those folks hunting in these states. If we hadn't finally been allowed to have regulars rifles, I would be looking you up! Good luck with the project !
