Here's another one of a 1 1/8 oz ball stuck over an inch into my 3d deer
Archery target. Greek throw at 20 yards.


I suppose that target is somewhat similar in density to actual muscle. Good shot, you achieve penetration with a sphere ammo.

Actually that target is much tougher than tissue. If an arrow were to penetrate
As deep as it would flesh you'd like to not get it out. Arrows from my 70 pound longbow
Onny penetrate this target about 4 to 5 inches.  Last deer i shot the arrow buried up to
The fleching with the point sticking out the other side about a foot.

I painted the glandes black and white, putting them a bit closer to the day they will fly on camera.

Great stuff guys.

Leadrocks, that pic of the deer target is a real eye-opener. Wow! Makes me wonder what a bi-conical could do to a real deer?

i have no doubt it would kill a deer. Whether or not it should be done is another matter. Smiley state laws here won't allow it anyway.

Rockman how do you remover the lead from the one piece mold? In my mind I see the lead just staying in the mold when it dries.

I was pretty good at slinging like 10 years ago.

Here's a drawing of my mould. It's very simple, just some white concrete on a container.
I made a bullet with modeling clay and let the mould dry. You have to use something soft and maleable for the bullet shape, otherwise it gets stuck forever.

Then, I scrapped the modeling clay and that's it. I use an electric stove like the ones you take for camping to melt the lead.  

I'm really diggin' the design; looks good, while being relatively easy to make.
Have you thought about making Hollowpoints? (I'm not sure if the glandes will travel fast enough for a hollowpoint design to be effective...)

I don't think that would expand. i have used a lot of hollowpoints for various firearm uses and it depends on a few factors, 1. speed- it takes anywhere from 700-900 feet per second to get expansion with lead hollowpoints. 2. hardness of the lead- many lead sources are actually alloys combined with tin. pure soft lead is getting harder and harder to find. 3. the type of material that the bullet strikes on impact. for example, soft materials (i.e. tissue or water) allow more rapid and larger expansion of hollowpoints than harder materials on penetration. when a bullet enters wood the resistance on the outside of the bullet is stronger preventing the bullet from expanding as easily than it would in tissue. i have shot .45 caliber hollow points into wood to later dig the bullets out and find they hadn't expanded at all. The same rounds expand easily in softer material. Just a little experiment i did a while back. Gallon jugs full of water and watermelons are fun things to shoot with hollowpoints.

Turn it upside down, tap  the bottom a few time and the lead just falls out.

Hi, I show you my ammo maker system.
Fishing weights molded hammer, marbles children. Some nails driven into the lead or stuck on the marbles. Small brass cylinder. Container wood slats.

separate the two halves, remove the wooden frame and refine the input lead
