This video demonstrates a DIY method for creating hollow point projectiles by modifying FMJ bullets using a Ryobi drill. The creator, identified as an experienced individual with expertise in ammunition types and reloading, tests the terminal ballistics of these homemade hollow points against standard FMJs in a clay lake. The results show a significantly larger cavity created by the DIY hollow points, leading to a discussion about potential accuracy testing for these modified rounds.

Quick Summary

A DIY hollow point, created by drilling an FMJ bullet with a Ryobi drill, produced a cavity twice the size of a standard FMJ in a clay lake test. This demonstrates a potential for increased terminal ballistics, though accuracy testing is recommended.

Frequently Asked Questions

Can you make hollow point bullets at home?

Yes, it is possible to create DIY hollow point bullets by modifying existing Full Metal Jacket (FMJ) projectiles. This typically involves drilling out the base of the FMJ to create a hollow cavity, as demonstrated in the video using a Ryobi drill.

How do DIY hollow points perform compared to FMJ bullets?

In a clay lake test, a DIY hollow point created by drilling an FMJ projectile produced a cavity approximately twice the size of the cavity made by a standard FMJ bullet, indicating potentially greater expansion.

What tools are needed to create DIY hollow points?

To create DIY hollow points, you will need Full Metal Jacket (FMJ) projectiles and a drill, such as a Ryobi ONE+ HP, to create the hollow cavity. Professional reloading equipment is also necessary for safe and proper loading.
