Frangible or reduced penetration bullets for .300 BO?

[DireWolf]

This thread got me thinking yesterday, and after a bit of background processing, came up with a couple ideas that I think are worth trying...

Worst case, I'll be out a couple hundred bucks (assuming I don't need to order any moulds made from HT 17-4ph or similar, etc.) but totally worth the effort if I can get something to work as hypothesized, and planning to order some project supplies this weekend.

It seems like available 'frangible' ammo is designed for safety (anti-spall, etc.) against steel targets at close range, hence the over penetration issues.

Normally would keep this to myself until after I've done some testing (but not in the bullet-making business, so would just as soon buy vs. build if available), but going to try producing some projectiles (thinking RNFP) using a powder/polymer coated and highly compressed W powder, to be used w/ gas check.

Just a hypothesis at this point, but thinking that a high-mass, high-velocity projectile which disintegrates (back into powdered-form) immediately upon initial impact may be possible...

What about psychological warfare?

Just make a creepy recording that you can broadcast throughout the house with reverb, a modulated voice, the lamentations of children in the background, etc.

Script:

"I see you have entered the fun house. Thank you, it's been 3 years since someone opted to play my game. This house seems like a normal house from the outside, and even seems normal from the inside. But you must know I'm an engineer that specializes in decorative obfuscation. Trap doors. Spikes. Flame throwers. My favorite part is the hidden room with 100% soundproofing for if you make it through the obstacles. Since I only want to play with mice who want to be caught, you have 30 seconds to exit the way you entered. 31 seconds is consent and I will activate all stations. ... oh, how well do you hold your breath, and what's your opinion of east German techno as a beat to die to? *techno music starts with slowly increasing volume...*"

Or yeah, just know your target and don't mag dump.

Why just go for the scare factor?

One of the in-progress "hobby projects" I've been tinkering with for a little while now is related to multi-layer/multi-stage (less-lethal, non-firearm-based), automated (AI/Scenario-driven), semi-mobile, home defense systems. Still early stage, and need to do more legal reasearch, but current thinking is that active AI-driven kinetic/acoustic deterrence is achievable without breaking the bank or violating any legal prohibitions...
