"The Last Crusade" Statistical Test with P3AT, Feb. 2006

This completes wetpack testing for the KelTec P3AT pistol that I started several years ago with the 1st gen AT. After 3 tests with the 1st gen and now 2 tests with the 2d gen, I have enough data to do a statistical analysis for a few of the more popular rounds.
Gelatin addicts demand a statistical report with their tests. Sometimes I'm amazed how they can get a statistic with only 1 data point, which is really all they get with a block of gelatin. The wetpack allows several shots in the same pack and with different ammo and different handguns, as the picture below shows for this test. Interesting is how the different barrel lengths respond to different brands of ammo. The Winchester Silvertip, for instance, expands too much with a long barrel and gets no more penetration than the short barrel. While the Hornady XTP doesn't develop enough velocity to expand well in a short barrel it penetrates well in the P3AT and expands and penetrates very well in longer barrel pistols. The Rem GS 102gr also seems to be a good all around choice.
A few statistics follow for the P3AT: (wetpack penetration is approx 2/3 gelatin)
Win ST, 13 tests, 6.6penet, mean, SD .88 and .520exp, mean, SD .025      equiv gel 9.9"
Rem GS, 8 tests, 7.56penet, mean, SD .85 and .574exp, mean, SD .014      equiv gel 11.34"
Speer GD, 6 tests, 6.8penet, mean, SD .37 and .463exp, mean, SD .029      equiv gel 10.2"
Fed HS, 5 tests, 7.8penet, mean, SD .4 and .479exp, mean, SD .002      equiv gel 11.7"

Note: Two FMJ rounds with the Sig P232 went 9+" and thru the 3/4" plywood backing. The Hornady rounds stopped at the plywood with the Sig pistol. One Bersa FMJ went thru the plywood.
