Expanding Bullet Set for Display at SHOT Show

Advanced Ballistics Concepts has designed a bullet that immediately expands once it exits the tip of a rifled barrel that it plans to display in Las Vegas next week at the 2014 SHOT Show.

Called the Mi-Bullet, the round acts somewhat like a multi-pellet buckshot, but the separate fragments of the round are connected and will expand to a pre-determined diameter after the bullet is fired. The Mi-Bullet expands to a diameter of 14 inches when fired from handguns and 24 inches from shotguns.

ABC officials designed the Mi-Bullet to improve first and second shot accuracy for shooters in “high pressure situations,” according to the company.

The Mi-Bullet supposedly maintains its accuracy by utilizing an accelerated radial spread aided by the rifled barrel, officials say. The larger diameter makes it harder to miss, the company said.

ABC designed three levels of the Mi-Bullet to include non-lethal (Mi-Stinger), semi-lethal (Mi-Stunner) and the fully lethal (Mi-Stopper). The Mi-Bullet is designed for most popular handgun and shotgun cartridges.

  1. It's been a while since I've seen this thing.
    Hasn't become any less complicated though…

  2. Ah the 'bolo bullet'.

  3. can not wait to try them

  4. Assuming a 185 gr .45, we’re looking at 3 60 gr projectiles moving at maybe 1100 fps., probably less. No thanks.

    "ABC officials designed the Mi-Bullet to improve first and second shot accuracy for shooters in “high pressure situations,” according to the company."

    Isn't that what we used to call training? I'll side with Crash, ballisticlly the rounds would loose velocity very fast and make them only effective at close and point blank ranges where accuracy should already be high with minimal training.

  6. May be more ingenious than practical. Can see many problems with a bolo bullet to much mancanics have to go right for a round in flight to the target. But still a ingenious idea.

  7. Might be great for turkey hunting !

  8. The true purpose of these genius rounds is to SELL ! Idiots and gadget freaks will buy anything just to have it or to be the "first on their block" to own it. Your technical explanations are quite good and on the money as well !

  9. Can somebody with a better understanding of physics than me explain how all three pieces expand outward and don't slow the round down instead of just falling straight behind which is what i would expect.

  10. The flatter surface area of the outer pieces would likely have more drag on them and therefor would likely stay 'behind' the center mass, so you're probably right seans. In order for it to stay in the same pattern as the graphic it would have to have an enormous amount of centrifugal force, which would mean it would have to be spinning very rapidly without moving forward too rapidly as the force of the drag pushing the outer shells backward would be stronger than the centrifugal force pulling them outward.

    I agree that it doesn't look too promising. Think I'll stick with my 00 buckshot..

  11. I would also be very interested to see a comparison of the muzzle velocity compared to say a couple hundred yards. I doubt these rounds would even make it that far before hitting the ground.

  12. The concept of the bolo as a non lethal entanglement device looks like an interesting addition to less than lethal force,

  13. 21st century micro-chain-shot. Ho hum.

    If you target is in a doorway or there is any obstruction (post, furniture, tree, etc) between you and the target there is a high probability that one projectile will snag and all 3 projectiles will miss the target completely.

    Oh yeah, and try using this with a suppressor and not only will the round not go anywhere but it will probably destroy the can and render your weapon useless until you get the suppressor off.

    Where do these people get their funding?

  14. I hope they are making this in .45 Colt because the Judge fanboys are going to go nuts over this BS round.

  15. The pieces expanding out could be shaped to interact aerodynamically and produce the angular motion that way. There likely isn't enough angular momentum from the spinning due to the rifling.

    Typical rifling is ~ 1 turn per foot. Angular momentum is R*mV. At 1000 feet per second, = 1000 revs/sec. At a 10 inch diameter end radius and a 0.125 start radius (the center of a 1/4 dia projectile), then 0.125*1000 = 10*12.5 revs/sec.

    I suspect that the strings would break if they hit anything.

    Chained shot is not legal for hunting. I remember someone having magnetized iron shot to give a better cluster (in theory). This was long before high strength magnets, so who knows if it worked.

    Does it come in 12 gauge shotgun?

  17. Uh?

  18. I liked the M198 7.62 back in 1968 Kontun Vietnam

  19. Hi, all. I enjoyed reading the comments, but I’d like to add a different perspective, one more in the line of Sharon’s question, as a concealed handgun instructor.

    Starting from the beginning, it seems in these conversations “effective” means “kill” or “wound,” and most of the comments follow that premise. I’d like to suggest “effective” means “to stop.” An assailant – or chl instructor – who is scared of being shot with a .45 is the same person who’s afraid of being shot with a .22. I don’t know what kind of wound this will make when it hits, but 99% of the people who have a weapon fired at them and then feel/see blood will (rightly) take themselves out of the situation.

    My perspective: any cartridge which makes the bad guy run away, especially after only one or two shots fired, will be given careful consideration.

  20. "If" this round does what it says. If the wire's hold, it would literally cut body's in 3+ pieces with the 12 gauge round.
