hello everyone this is jeff of TAOFLEDERMAUS - we have something very cool
to show you today
these are what we call TURBINE rifle shotgun slugs - a professional machinist
named Tim Hamilton contacted me and said hey I made these rifled slugs for you
out of aluminum and I'd like you to shoot them
a year or so ago a channel called artisan Tony made us some 3d printed
shotgun slugs or bullets
Wow but these had some stability issues they tumbled around and a lot of viewers
suggested hey those things need to have rifling on there to make them spin
ok that's that make sense so tim hamilton decided hey I'll make some
aluminum slugs with rifling built in them that which will cause them to spin
as they travel through the air and that of course is what keeps a normal bullet
flying straight to the air the gyroscopic stabilization and Tim went as
far as design these with three different twist rates and a twist rate is simply
how far it has to travel to make one complete revolution in this case it has
to travel 10 inches to make one revolution
now these rounds look very promising they're very precisely made balance all
the pins are perfectly spaced there's six
Milt slots in each one and each round weighs seven tenths of an ounce or about
20 grams
according to the scale each round is basically a 70 caliber slug 2 inches
long and that's a 50 caliber bullet just for comparison
so now is the moment of truth to test these things out
very excited to try and they load very nicely into this mossberg 590 smoothbore
shotgun with a 20 inch barrel
ok shot one hit
so far it looks pretty promising there and hit the target target was
approximately 20 yards away but it landed on target
hit it oh man here that ricochet
yeah hit it
let's see how it does using a Rio high brass round
I
yeah
and then for the final shot will go back to the phe low brass using the one in
twenty twist slug
they're hitting that's a good thing
yes Darren was able to hit the target every single time
not the smallest of targets each target was approximately the size of a sheet of
paper and a half inches by 11 and you can hear you can see the various impact
points and some of the damage caused by these slugs the final slug actually went
through this computer hard drive and halfway into the phone book that was put
behind it
now this is the only slug with we actually found the other ones ricocheted
off in different directions
we may be able to find those at a later date but you can see how the nose of it
is very smash
so that's promising it could have been flying straight the fun part for me is
coming home and watching the high-speed footage and seeing what actually
happened
now we've got three high-speed cameras there
casio xf1 pro high-speed cameras and were you shooting at 300 frames per
second this is six hundred frames per second and then twelve hundred frames
per second
sure they're not phantom high-speed cameras costing excess of 400 thousand
dollars but they're great for field use like this for field testing
now if you remember this shot is the one that when it struck the plate
it kind of song actually sounded like a turban business and you can see how the
slug hit the bottom and shot upwards at a high velocity
but consistently the problem we're seeing is the rounds are tumbling
yeah they're more or less stain on target there's a slight deviation in
trajectory but for the most part there
keyholding and flying sideways and are tumbling around but this kind of gives
you an idea of how complex supersonic aerodynamics really is what you think
would work doesn't always work but in the past we've had some very good
success with some rounds made by a channel called HW 97 carbine and yes we
will be showing a few more of his rounds in the very near future
you know there's a saying that goes
if you aim at nothing you'll hit every time so I definitely appreciate when
people have enough curiosity do to make something like this because you never
know what's going to do until you actually take it out try it
so it's folks like HW 97 carbine and tim hamilton who are generous enough to with
their time to allow us to try some of the rounds of the design and speaking of
tim hamilton
he was kind of to make a video on how he made these how he designed them showing
some of the machining that machine tools the very sophisticated cnc process and
please check out his video
he's got other ideas in store - so it might be a good idea to subscribe to him
and see what kind of ideas he's got up his sleeve
I definitely want to thank him for
all this hard work i wish they would have worked but a wheel at least learn
something
so if you got any suggestions for Tim go to that video and tell me your thoughts
thanks for watching
