I need to locate Figure 5-2 in MacPherson, Duncan (1994). Bullet Penetration: Modeling the Dynamics and the Incapacitation Resulting from Wound Trauma. El Segundo, CA: Ballistic Publications. It is referenced as a means to correct for BB penetration in ballistic gel. My local library doesn't have it and neither does my university library. I can't afford to buy the book on Amazon and my limited Googlefu has been unsuccessful. Any idea on where I can get hold of just the figure in question? While I'd love to read the whole book, right now I'm just interested in the correction method.

Oh, and because this is GD, I guess there should be an entirely unrelated pic of a fucked up looking cat:

http://publications.gc.ca/collections/collection_2008/ps-sp/PS63-2-1998-3E.pdf  Is this the publication you're after?



ETA that's prob not it, hang on.

Interesting stuff but not what I was looking for. Thanks, though. MacPherson developed a method of compensating for .177cal BB penetration in gel so that if the calibration shot wasn't exactly the right depth, the block could still be used. His method was referenced in several places but I can't find the chart that you're supposed to use to do the correction.

I came up dry, sorry mate.

Thanks for trying, at least.

Lots of references to it not much actual data.

eta: Might have better luck posting this in the Terminal Ballistics forum. Someone there probably has a copy of the book or at least knows the correction method.

Why is James Carville at your house wearing that funky sweater and cap get up and no underwear?

Inter Library Loan. It's free.  Use it.

That was my next step. Was hoping for something quicker.

Sorry ammo forum I meant. Terminal ballistics is a different website. http://www.ar15.com/forums/f_3/16_.html

Cross posted in case someone has the info. Got a link to the other site's terminal ballistics forum?

I was thinking of M4Carbine. I think links are frowned upon here so just Google it.

Is it possible that it could be as simple as dividing the target penetration (3.5") by the actual penetration and multiplying the result by the actual penetration of your test projectile?

Ok, thanks. I think mods are okay with it as long as you're not advertising or linking to something with non CoC compliant content. At least they're okay with it in the tech forums.

I have a copy of the book if someone doesn't post the figure.  It was re-printed in 2005 because of its popularity and that's when I bought it, back when I actually came here for information about guns and ammo.  Figure 5-2 is on p.84 of the 2005 edition.

Thanks, C-4. Apparently I'm not bright enough to figure out how to use the chart, though. It looks as though you follow the actual velocity up to the line corresponding to the actual penetration and that tells you the correction, but that would yield a corrected BB penetration depth. In the other references, they made it sound as though you could calculate a correction to the test projectile depth if the BB didn't calibrate perfectly.
