Hollowpoints are certainly more expensive, and worth it. This simple technique could be a money-saver for those who reload or who have a supply of ball ammo available.
I wonder how well these DIY Hollowpoints perform? It is likely that they cause much more damage but I would like to see it.
One problem with Full Metal Jacket 9mm is the speed of travel. It runs right through targets like a laser, often inflicting minimal damage. These DIY bullets are certain to slow down a bit. Enjoy!
