45 ACP Gold Dot test: regular vs short barrel from XDs

(from Sep 2013)

In this video I compare the standard .45 ACP Gold Dot 230-grain ammo (part #23966) against the .45 ACP "Short Barrel" Gold Dot 230-grain ammo (part #23975). I fired both into ClearBallistics.com's synthetic ballistic gelatin, and compared the average expansion, penetration, and velocity to find out what the differences are, and what the preferences should be, for the Springfield XD-S and its 3.3" barrel.

Also in this episode, I use the corroborating mathematical formula, the Quantitative Ammunition Selection (QAS) formula (by Charles Schwartz) for predicting bullet penetration in ballistic gel. Adding this formula to the results helps correct for excessive "bounceback" where the bullets penetrate deeply but bounce back into the gel, thus coming to rest at artificially shallow penetration. The Quantitative Ammunition Selection formula is available in book form at www.quantitativeammunitionselection.com.

Note: I'm not making any claims for these videos other than that these are the results I achieved, in my own testing, from the stated pistol. I have no intention to make a blanket endorsement or indictment of any product, only to review and report what I found in a given instance. Obviously it is incumbent upon each individual to conduct their own research and make up their own mind about which defensive ammunition is best for their own purposes, in their own firearms. Also keep in mind that individual firearms can be persnickety; my XD-S may feed a particular round consistently whereas your XD-S might jam on those rounds, so -- please conduct your own testing before trusting any particular ammo.
