So, I was browsing for .223 ammo, and I stumbled across a contest for 400 rounds of .223 ammo. Basically it's one of those "guess how many are in the jar" things.

 

I figured I'd share it to encourage everyone here to enter, and, should you win, you should totally split some ammo with me XD. Not kidding.

1,364 rounds!

Haha, you have to actually submit it on that link there.I tried doing some calculations, depending on the variables which I assumed, I got anywhere around 693, 936, and about 1200, though I believe that latter one to be an error.

IDK, I have to share it on fb, and fill out forms that's alot of work. How did you calculate variables? We don't know the dimensions of the cookie jar.

I measured the jar on my screen, found the volume of that. Then I measured the round's casing, ending where it bottle necks, and found the volume of that "cylinder" from the bottleneck, up to the tip of the bullet, I found the area of that "cone" and added it to the other one. Then I multiplied the volume of the jar by .65, since it is obvious not all the space in the jar is used, due to the irregular shape of the bullets.

You measured the jar on your screen? Is there some known object to compare it to? Otherwise that measurement means jack.

Well I measured some of the ammo as well, most of which, on this screen, came up as having a casing with a 3cm length. then I simply compared it to the actual dimensions of the 5.56, as found on wikipedia, and used that to create a scale.

 

Look, I didn't say my method was perfect, I just figured it may get me a little closer than pulling a number out of my rear. I am also praying that if someone on here wins, they'll throw 50 rounds my way. XD

400 is my guess

401....

You principle is sound.. 0.65 is too high a multiplier. M&Ms pack in at 0.68 and ammo would be a lot less than that. My guess is 683.

The known object is the .223 cartridge.

Damn you Paul...

Wow, talk about free advertising!

400 is my guess

 

and the number is 399.99!! heaterbob...COME-ON DOWN!!!!

That's one of my answers, but I've only recently had need for .223, so I'mnot familiar with how big the round is. I guess I under-shot the amount. I kept getting around 1,200 on some of my calculations.

480

good guess. Winning guess was 1022.
