Bombay B.S

Oh yes, one other thing about the event. The bombay paper that wrote it up described the terrorists armament as:

Every man was given six to seven magazines with fifty bullets each, eight hand grenades per terrorist with one AK-57, an automatic loading revolver and a supply of dry fruits.
Typically AK magazines hold 20-30 rounds with 50 being rather rare, but what I really, really want to see is that AK-57 automatic loading revolver. I shoot revolvers myself, and that would be a real boon because reloading always takes so long. I hope the dry fruits aren't part of the process. I'm familiar with the external ballistics of some vegetables (pumpkins) and believe me, they're nothing to write home about.

I suspect that the ballistics of carrots (fired blunt end first, and probably requiring a sabot to reduce windage) would be better than those of pumpkins. Lower sectional density would likely result in shorter maximum range, though.

search project worthy of a mad scientist. Get a 4 or 5 foot piece of 3/4 or 1/2" pvc, cut rifling on the inside, and bring it over. I'll set up the chrony, and we'll bait some squirrels, which should be easy after we hit the back fence a couple times with the carrots.

Question 1: Where does one find a 5', 1/2-3/4" tap?

Question 2: How does one pay for it?

Besides, the point of firing blunt-end first is to start in an aerodynamically stable position, so spin might be unnecessary. (Arguably, with an inherently irregular organic shape, spin could induce more instability than it prevents.)

Sort of a SPRSDS-CE* round.

For cutting rifling you need a rifling button, a small plug that leaves grooves behind it in a spiral pattern as it's pulled through the barrel.

A competent machinist could probably make one. A machinist who is certifiably on the cutting edge of what we refer to as "sanity" would probably make one for free in return for trigger time and beer.

I wonder which machinist you might be talking about. There are so many obvious choices. 8-)

Actually, I can see a couple of engineering papers coming out of this:

"The effect of spin stabilization on irregular projectiles in atmosphere"

"PVC wall-strength variation with rifling groove depth"

The latter could be moderately frisky to test.
