Disclaimer: This is not a serious project, just a bit of a pet project to see what I can come up with as an experiment.
I have been toying with an idea on how to go about modifying existing hollow point ammo. With standard ammo, you have a lead core wrapped in a copper jacket which is open in the front to allow for the bullet to expand. My current idea is to take an existing Winchester .40 cal 185grain hollowpoint, and mount a 4.5mm zinc coated steel BB to the cavity in such a way as to have a similar design as the Hornady Critical Defense rounds for sale.
I'm only looking to modify a small amount of bullets for testing purposes only. The idea is that the BB will round off the nose of the hollow point, thus increasing the penetration value while at the same time, allowing for an object that is harder (more dense) then the lead core of the bullet to aid in the expansion of the bullet once it penetrates a thick layer of clothing.
Here are the factors involved...
#1 S&W .40 cal Winchester 185 grain hollow point bullet
#2 Daisy 4.5mm (.177 cal) zinc plated steel shot BBs
#3 some sort of easily manipulated adhesive/molding compound such as wax or modeling putty
I'm not looking to modify the powder charge of the bullet or anything of that nature, just experimenting with making an existing type of ammo to make it more effective. I'm not looking into a debate as to whether this should or shouldn't be done I'm only interested in the feasibility of the basic physics involved with the design. I know there are people out there that hand load their own rounds making them with more powder and such. I'm just curious as to if this would work to turn a $20 box of 50 rounds into the equivalent number of higher grade rounds found for about $25 for a box of 20.
Once I have a small number of viable rounds to work with, I'd be interested in testing the function of such rounds on test media. At that point I would need serious reliable information as to what to use. I'm thinking a series of 1gal milk jugs, filled with water and then lined up next to each other and with a few layers of say old jeans to represent clothing on the target.
Any thoughts?
