9mm frangible for defense or offense.

[Ammosmith]

I have honed down and debugged the process to make a better Glaser bullet for the 9mm. In theory it should be a deep penetrating and fragmenting bullet. These weigh 115grs. The Glaser weighs about 60grs. More mass more damage.

So let's get into specifics:

The jacket is trimmed to .650"
30 caliber gas checks
#9 lead shot
All the bench tools required
A lot of patience.

Core weight: 91grs
Jacket/gas check combination 24grs

Here are the basic components in the scale pan.

This will be the point of the bullet. Notice the Damascus appearance to the lead. This is because the lead, even-though smashed together do not bond due to the lead oxide. This allows the core to disintegrate upon impact after the jacket is shed.

Here you can see the 30 caliber gas check. This will form and seal the base. It's recessed in order to keep the shot core captive.

The semi closed base is basically formed at this point.

here we see the Left: The top of the bullet with the point not yet formed, Middle: The base in second to last step with the edges radiused in to help form a solid base, Right: The base is closed and is ready for point forming.

A look inside the jacket before point forming.

The finished bullets...one last step...using clear fingernail polish to cement the tip to keep the core glued in..it's my daughters nail polish BTW :rolleyes:

A close up of the point aka meplat. You can see the core wanting to separate from itself. This is why these are so nasty.

Range test coming fairly soon. I'll take them on my camping trip.

i done a similar with my 44's but hollow pointed and used a ww base core.
i seated the ww core with some glue, then used a notching die to open/cut the case then filled the rest with shot, and point formed around the deep hollow point.
i also used a canellure to stop the opening of the case at the ww core.
wet cardboard and rags, would catch the base and opened jacket [very opened jacket]
with only the core and annealed case left.
i was running them at between 900 and 1200 fps.
i wondered if any of them flipped after shedding the nose contents, as i would find some of them opened wide and sometimes they were folded over on one side.
i was mainly using some soft #5 shot but wondered if bigger or smaller shot would make a difference in the wound channels depth.

I am very interested in seeing how you go with these both accuracy wise and how they perform in some ballistic media. Just one question, Ammosmith, what is the .650 jacket cut from? You probably mentioned it in your first post but I cannot see it.

I have had trouble with the core separating so I use a plastic or cardboard wad over core before I form point. Mine were 22 caliber The tries I have had with 45 also broke apart to easy to handle load and cycle in gun.

Thanks for that, Ammosmith. I think that those things will do some spectacular damage in wet newpaper/wet cardboard tests.
