Hollow point expansion

[jtmaze]

Does anyone know if a jhp bullet will expand when shooting into loose sand? My daughter needs some expanded hp bullets and fired shell casings for her criminal justice class in college and I have never intentionally tried to expand a jhp bullet before. If not does anyone have a good media that will stop a bullet that can be made at home that will expand a jhp round. Using white box winchester 230 gr jhp 45acp.

I had to do the same ballistics testing for a paper I had to write while I was also in college, I used line of milk jugs filled with water & I was able to recover most of the rounds.

Cool. Did water make the rounds expand. I think she has to do some comparison between jhp and fmj cause she asked for both. Not really sure but will try that.

Fill a milk jug with wet newspaper. That should get the rounds to expand.

Yes, water will make them expand. Line up a few milk just or two liter bottles with water and shoot a round into them. Maybe put the jugs in a large cardboard box so finding the bullet will be easier.

bundle the newspaper then soak it

line the bundles up and shot into the bundles make sure the bundles are about 3 feet thick front to back

Thanks guys. Water and newspaper will be my route. I have plenty of both.

She just needs 1 caliber for now I expect more later. She needs them Monday. Will get a list together when she gets home cause I am sure there will be more later. Thanks for the offer.

This was a neat experiment. Five gallon bucket about 16" of sand fill bucket with water. Three rounds but bucket didn't make it. If you want to save the sand or take you time shooting use two buckets. Sand stopped bullets but pressure blew the sides out of bucket.

I once tried this with phone books, and was able to recover the bullets.

You can try the 50 gallon water drum + ladder methold ....

I've seen several video's on youtube when they test JHP's. Seems a bit easier the going through lots of milk jugs

This guy tests LOTS of ammo -- Both jug test and this test. See Here:
