Find 12 ga 510 sabot inserts and stick a ap 50 cal in there. Probably cheaper and easier.
ETA: 3d printer for the plastic, turning hardened steel is a bitch if you don't have the knowhow or tooling. |

I guess my question would be "Why?"
You can get more effective rifle ammo for much cheaper with no time invested. |

If you really want penetration, why are you screwing around with shotgun slugs to begin with?
Besides.... Unless you have some kind of a sabot, any kind of steel sufficiently hard to improve penetration is going to tear the fuck out of your barrel. |

Turning something like that on the lathe would be easy, but the time/cost per unit would probably be bad unless you had a CNC lathe pumping out tons of them. A notch could be made for where the plastic goes, and the plastic just pressed on. |

A pointed steel slug of any sort, such as 1020, will be much better than a flat-ish lead slug. It need not be a tool steel, although that would probably help. And a standard wad should take care of the barrel just fine, as long as it isn't choked. Just don't expect to be able to shoot very far with it in an accurate fashion. The idea of a. 50 bullet is a good one. I have no idea what NFA or DD would apply, so mind that at your own risk. |

Shotgun slugs are devastating on soft tissue, not so much if there's much of a barrier in the way. If I were to do something similar, I'd make a sabot round using a .50 projectile. Point set back into the hull to avoid coming in contact with the next primer. Problem is, that would make it short and light enough that again, there are much better choices. IMO the only reason to bother doing this, is simply because you want to-and that in itself is a perfectly valid reason, but be aware you'll probably spend a shitload of money making it work. |

At $3-$5 per round...and I think that's a cheap estimate...I can't see pulling the bullets out of my .50BMG rounds. I'll admit though, it'd be pretty entertaining to see one of my API or better yet APIT rounds go through something dense up close. Plus the DDupleks slug rounds are around $2 a pop. Thanks -Emt1581 |

Looks easy enough. Use the taper setting.

Brennekke super sabots are pretty wicked, give those a try.
At the PD range, they stacked 2 level 3a vests and shot them at 10 yards, ended up stuck in the last panel on the second vest. |

Cut rod into leangths and turn to your desired point. Make slugs, Drill 3/8 hole in center, epoxy in. Lee slug mold $16 eBay 3ft x 3/8" hardened rod $20 ebay Epoxy, $4 Or you could just cut rod and stick in a regular wad if your bbl has no choke. This is all assuming you have the correct ffl to manufacture said item since the ATF says no go according to its definition. |

Rifled barrel only.  IMO, the testing videos on OP's ammo are much smoke and mirrors. The Russian engine block wads paper thin and the carburetor stopped one round dead.  The Hexolit round looks like the best of the four. |

Low velocity, large caliber, short projectile and armor piercing don't go in the same sentence.
You're wasting your time in more ways than one. |

The original BRI 3" 12G slugs had a "near armor piercing " phony rep & we're even in a movie, going thru cars to (of course) kill a cop. When Winchester acquired them, they switched to softer lead.
Centering the projectile is extremely important for accuracy, if one were to try this. There are some YouTubers who stick anything & everything into 12G shells & shoot them, with predictably poor accuracy. They used nails, dimes, batteries, etc. I think the Duplex slugs are the safest, cheapest ( in the long run) way to go. Or, .308 AP

Chuck Taylor did penetration tests YEARS ago for SWAT magazine. He included a shotgun.
The standard Brenneke slugs did the best against stuff like car doors and glass. I believe this was before the sabot slugs became popular. But the Brennekes did considerably better than the standard round nose soft lead slugs. If I want to pierce armor, I sure ain't grabbing a shotgun. |

This is all assuming you have the correct ffl to manufacture said item since the ATF says no go according to its definition. 1. Get tungsten welding rod, and turn it to the correct length and tip profile to weigh about 25 grains to make a penetrator. Tungsten dust is apparently highly toxic.... Maybe use steel and harden it afterwards? 2. Get some 90 grain 9mm/380acp hollow point bullets. 3. Press the penetrator into the hollowpoint. 4. Load on the high side of 9mm 115gr specs for maximum velocity. I figure you'd have to do some work to ensure the penetrator gets seated deep enough into the hollowpoint that it doesn't wreck your feed ramp, and centered true enough that the bullet is stable in flight. Ultimately though, you'd just have some AP pistol ammo. Not so useful in a world where NRA members are already killing cops everyday with M855 and 7N6 from our AR pistols. I would enjoy the challenge of making it work though. |
