Guess for a giveaway

(I know, Phssthpok, I still owe you some kind of bag of crap!)

I was digging in my safe today trying to find a particular piece of paper, and realized I had an inordinate amount of loose ammo rolling around. So I gathered it up into one container. Then I decided I'd make a game of it, and put a prize on the game.

How many rounds of ammo are in this bowl??

Here's the picture:

For a sense of scale, those are quart jars in the background, and the semi-wadcutter in the very back of the container is a .44Spl. Calibers within range from .22LR to 12ga.

Put your guess in comments. One guess per person - if you guess a second time, it doesn't count.

I'll let this run for the rest of the month.

And the prize, by the by, is an Aimpoint. Not a knockoff, a real (yes, and functional) Aimpoint. So be willing to share your shipping address with me.

Ready? Go. (Link it out, please - and have fun!)

ETA: Pediem asked me to clarify. It is closest, over or under. If the number was 10 and the guesses were 8 and 11, 11 wins. If two (or more) people guess the same, I'll roll a die or flip a coin or something.
