Shot some rounds in sand to see expansion..PICS
THIS WAS THE OPPOSITE OF SCIENTIFIC. THIS WAS ME HAVING FUN AT A WMA FOR THE FIRST TIME. I JUST WANTED TO SEE WHAT HAPPENS WHEN ROUNDS HIT SOMETHING.
Now that is out of the way.... MZMTG and I went to a WMA here in GA. VERY north GA. Very nice place. It was my first time there and I was very impressed. All day shooting for $5, covered shooting area, benches for rifles, outhouse, and benchs to sit on.
Before I went I wanted to "test" what rounds did after you fired them. I know that there are 1000's of people who have done this 1000's of different ways. This was for my pleasure only. I took an old cooler and put ~4 lbs of sand in it. I shot it with my .45 and MZMTG shot it with his .40. Others shot it, but I did not have pics of there rounds. We were ~15 ft aaway from the cooler. Now onto the pics and small descriptions.
From the firing line
I was VERY surprised at the LACK of expansion of .45 hollow points. The .40's "seemed" to expand at a more frequent rate. I did not count how many did/did not expand. Just picking the rounds up form the sand more .40's expanded than .45's. The .45 round was Remington UMC javketed hollow points. ~$27 for 100 rds from WW. In my kimber, I have shot ~150 of these with no failures of any sort. This is now what I carry. I DO NOT know what MZMTG shot in .40.
So here is a lineup of .45 hollow points and a Winchester WB.
As you can see, the hollow area filled up with stuf from the cooler
Digging the styrofoam from inside the round I found the plastic from the cooler, funny how this round was tearing on one side
This round had almost zero expansion and more stryofoam and plastic
Here the rounds are next to an unfiored round
Here are the unkown .40 hollow points, better expansion than the .45.. it should be said that the FMJ .40's were fully intact just as the .45 fmj
I did not remove anything from these rounds. They did not collect much styrofoam or plastic
The cooler... it is worth note that the cooler did not leak sand after we were done. I left it there for the others to shoot.
All in all a fun day at the WMA. I'll be going back soon. Like I said, not proving anything, just 2 guys out shooting stuff. I just wanted to better understand expansion and other things.
