45 AUTO UNDERWOOD 230gr JHP +P Review

[RDub]

Hello
The 45 AUTO reviews that I did were shot with a Walther PPQ 45 with a polygonal 4*¼ inch barrel.

First I do forensic exam of the ammunition. Next I shoot a group while chronographing. Targets were were set at 15 yards. Chronograph is a Oehler 35P

Then one round of each ammunition brand is shot into a 55 gallon plastic barrel of water. The bullet is then recovered, photographed and then measured for expansion. In cases where the bullet fragments and loses its jacket, a weight is taken with all the recovered material and also a weight taken with just the lead core.
Here is the link to all the photos of the review;

Data Sheet

The slightly over one inch expansion of this bullet is quite amazing. Expansion was very uniform with no jacket separation. Accuracy good and recoil was a little more than most, but manageable. Outstanding performance overall.
Midway lists this for $1.26 per round.

The photos of the expanded bullets were amazing.
I may get some. Thanks

RDub, impressive ammo and test. I bough a short case of Speer G2 LE 45ACP +P a couple of years ago. The hollow point is shallow, but similar to the Buffalo Bore, and filled with the Speer elastomer. Firing into water I got ~ 3/4" expansion from my RIA 1911 and Ruger American 45. The Buffalo Bore may be on my shopping list as well.
