Russia claims their new future body armour will stop a .50 cal.

Highflyer40,
You made reference to our cousins over the border having a longer a longer sniper shot.
Appreciate hearing about tbis I.m interested
1.Type of sniper rifle used.and make.
2. Calibre.
3 When this took place and where
4. How many enemy did he obliterate.
5. If there were no kills involved who cares without kills involved its a waste of time.
6. The Snper involved in what I referred to hiw far do you rekon the bullett would have traavelled if it had not had to blow these 2 insurgents apart.
You will notice I did not use all caps just to keep you HAPPY.

Milk glue soaked layers of linen was used by the Greeks .
Their Greek fire is still a mystery , some old ideas are new again .
I was disappointed when I thought I had an idea for a patent , my patent lawyer friend did a search for my great idea before it got too expensive down the rabbit hole money drain that some patented ideas pull people .Some guy at the Winchester factory had already patented the idea ninety years before I had thought of it

Just when one thinks one knows history and blurt out random historical facts to impress friends , be careful enough who your friends invite for coffee. When the assassin of the Duke came up . I thought I was knowledgeable because I could remember the name of the gunman from school . But one of my friends coffee friends seemed to know the names of the four other killers waiting on the street . He smiled after naming them as he teaches history . The list has grown to six assassins involved now . Not really sure if the list will grow any larger .

That Silk protection was available to the Arch Duke and not used is incredibly interesting , thank you for sharing that .

Let me google that for you.

Wikipedia aside the JTF-2 kill in 2017 made the news in most major outlets, not sure why Karnak66 is so baffled.

Not like it hadn't happened before either. With a small military and shrinking budget (for the military - progressive causes, no limit) Canada has to prioritize various specialities.

More astonishing, perhaps, is the fact that over the last 15 years, the active-combat sniping record has been broken four times, and three of those have been by Canadians.
A Different Level of Military Sniper

(Article from 2017)

Ok back to body armour etc.

Imagine a ten pound gun firing a one ounce bullet at 1600 feet per second. It will recoil at ten feet per second. Momentum is 10*10 = 100 foot pounds. That's also true for the bullet 1/16 *1600 = 100 foot pounds.

Kinetic energy of gun is 1/2mv^2 (5*10^2) = 5*100 = 500 foot pounds.

Kinetic energy of bullet is also 1/2mv^2 (1/32 *1600^2) = 1/32 * 2560000 = 80,000 foot pounds. It's 160 times as much.

I don't know the actual values, this is illustrative. The recoil will also include that from the high velocity gas propelling the bullet, but I believe recoil suppression devices vent much of the gas backward - at the cost of making the gun even louder. I have never fired anything bigger than a 12 bore shotgun, and that is loud enough for me!

1 pound =7000 gr ergo 1oz is 437.5 gr Easy ke formula is (V*V)*min grains/450240) so your above 1oz shotgun slug at 1600 fps is about 2487 fpe And that is quite a stiff load not 80,000

Worth checking the numbers, one pound is 454 grams, not 7000.

g = grams. gr = grains. 1lb = 454g = 7000gr.

Having been smacked between the shoulder blades by an AK-47 round fired from close range the energy is plenty. Body armour being hit by a .50 is going to bowl you A over T, how is the energy imparted being dissipated, shock wave induced over pressure on the body? Wiki gives the AK-47 round as 1,469 ft.lbs.

Sir, would you mind telling more of this event?

Without looking at the numbers, there are plenty of Youtube videos showing chunks being blown off sections of railway line or anvils using a .50 cal rifle. That doesn't instill confidence in this new body armour.

Thanks, guess that is why they suggest gm from gram rather than simply g.

Sir, would you mind telling more of this event
Don't mind at all. I was lead of a five aircraft formation sent to Ben Tre (the city made famous by it had to be destroyed in order to save it) to lift troops to a spot some kilometers east of Ben Tre to secure the ground for the establishment of a fire support base.

After the brief at Ben Tre on start up my aircraft had a motorised starter, ie wouldn't change from start mode to generator mode. I then took the place of the co-pilot in the number two aircraft and we proceeded with four aircraft for the troop lift.

The co-pilot was flying and on touch down in the landing zone I thought "J...s, that was a rough landing" as my seat slammed forward on its rails. Events happened instantaneously, the cockpit filled with a talcum powder like substance (later found to be from the round impacting my seat which has a ceramic layer), the gunner rolling around on the floor screaming "I'm hit" (in the back and neck), the crew chief laconically observing "I've got a guy at 12 o'clock with a weapon", to which I replied "hit him"

All four aircraft made it out of the landing zone, one was required to make a force landing shortly after and the other three aircraft made it back to the pick up zone where their condition required sling loading by Chinook back to base.

Of the forty troops we dropped 50% killed, 25% wounded, only two aircrew wounded. My gunner was beside himself because when he was hit he fired a burst of M-60 into the backs of two disembarking troops. While he was having his wounds dressed I tried to assuage his feelings by "It's war son, **** happens". Think about him to this day and wonder how the event has shaped his life.

A Chieu Hoi (VC deserter) later said they had been lying in ambush for a week.

The roll of the dice, the ten troops left behind by my aircraft going U/S lived for another day because of the only unserviceability I had during my tour.

I think the last Brit to be shot by the IRA in Ulster was hit in the back by a 50 cal, he died of course but the round ripped off his belt buckle which then seriously injured the lady driver the patrol were speaking to. It seems because he was bending over to the car his area of back was exposed below the jacket name deleted hoping to avoid further pain to living relatives. When I made this post I was seeking to remember a troop who died in our service. We must not forget such or who killed him

One of the guys that used to fly with us was a Nav on a Beverley into I think Aden and on finals felt something wet, looking down he realised he’d been shot through the leg.

The dynamics of ballistic flight is probably why Fairchild aircraft corporation was able to contribute to making some interesting contributions to firearms .

I forgot that one pound force is the force exerted by a mass of one pound under gravity of one foot per second^2, not earth gravity of 32 feet per second^2.

Divide my figures by 32. 80,000/32 = 2500
and for the gun 500/32 = 15.6

Not used to grains, or even pounds force, but yes, essentially I agree with you now.

Amusingly the energy of the bullet is also about five horse power seconds. If you have a horse working hard for five seconds to create kinetic energy in a small projectile and apply it to you, it's going to do some damage.
