Extensive new wetpack test: .380acp, 9mm

A friend over at KTOG recently performed a herculean wetpack test, covering the pack with clothing to approximate seasonal variations. I thought some of the folks here would find it interesting. A lot of work involved, and some interesting results:

thanks also for the link. Interesting to see what others are doing. A few comments...

he mentioned smileys on the FMJ rounds which are very obvious, and deep, in the photo which almost looks like he was using a first generation P3AT pistol with an unmodified feed ramp. We know from tests several of us have done that a 1G P3AT smiley will have an effect on JHP ammo most of the time preventing good expansion. Unkown if that was a factor there since a lot of JHP expanded, some didn't.

I'm also amazed at how he got 60 shots into one wetpack without a lot of interference between bullets, hitting each other, etc. I try for 14 - 15 maximum and less if possible.

But still, a worthy effort that took a lot more work than I'm willing to try in one study.

Cheers,

og

I missed the smiley issue, og, thanks for catching that. Although my 1G gun causes mild smilies, there has been no effect on performance in the wetpack tests I've done. This gun seems to cause more severe smilies however. My sense is that it would not necessarily limit expansion, but rather cause asymmetrical expansion, as we see in many of the bullets. Who knows.

thanks, dt, yes, we still have a lot to learn about this ballistics issue. With all the good efforts going on, eventually there will be someone with enough money and time to come up with a real good scientific way to do tests that we all can duplicate easily. I'm getting too old (and poor) to set up a lab to explore this much anymore. I like the work the box'o'truth guy is doing, but his setup is a little expensive for me to try. Waterjugs are good too, but again a whole lot of trouble and my range forbids them. Big sign says paper targets only, wetpack OK since it's paper! Ideas??

Cheers,

og

I actually think wetpack, if properly prepared in a consistent manner (24 hour soak, pulling out the shiny inserts), is about the best "poor man's " ballistic test available. What I most like about it is that you can test multiple rounds at the same time with minimal trouble, in order to compare different brands head-to-head, or one brand for consistent performance. All the other methods (waterjugs, playdough, gel-like "tubes," etc.) can only test one round at a time. The only problem I have with the wetpacks is lifting the darn things. Later, DT

Very interesting test, and the results are illuminating. I don't carry a .380 any more (haven't for years) but might reconsider my position on this with the American Eagle ball ammo if a 3AT happened along.



Thanks for posting this link, dtwilly.
