Making Better Golf Ball Projectiles - Gunnar Watt

The idea for the heavier golf ball ammo came when I realized that I did not have the slightest idea on how to cast glands out of lead. The idea was just a spur of the moment thing just like most good ideas a person has. I liked the idea of ammo you could go buy at the local Wal-Mart. Golf ball are the answer. The heavier golf ball to me would be more forgiving ammo for the beginner. Even though I have been around this website for sometime and am fairly accurate with my sling, I still consider myself a newbe. That is why I hoped to make cheap, simple ammo for the beginner to be able to go to the store and make with relative simplicity.

First a person will have to find the right golf ball that can be hollowed out. You can use real golf balls or practice golf balls. When the thought to hollow out a golf ball came to me, I just picked up the first golf ball I found. With some luck on my side I found the right golf ball the first time, and I drilled into it.

When you drill into the golf ball for the first time, You will be surprised! The golf ball that will only work for this project is the Titlesit Tour Distance 90. The reason for this because it is filled with rubber bands and a corn syrup-water mixture. Most newer golf balls will not work because they have a plastic though the whole golf ball. When you drill into the center of the golf ball (and yes you have to drill into it), the liquid is under pressure, and it will spray out with some force. Safety glass or a face shield is recommended. After the golf ball has relieved its pressure, you start to saw with a metal saw.

Saw directly in the middle of the golf ball where you drilled you hole at. As you are saw you will start to hear the rubber bands start to crack and break. You will need to saw about 1/4 to a 1/3 of the way down into the golf ball. The farther you get the more noise the rubber bands start to make. When you get to about 1/3 of the way down, the rubber bands will start to press on the sides of the golf ball. This is all normal. As more and more rubber bands start to break the pressure builds up and shoots the plastic center out. You still need those safety glasses because some times the plastic center comes out with some force. A bench vise or a pair of vise grips helps with the plastic to come out a little easier. Next keep the vise or vise grips handy because the vise help spread the ball enough to get out the rest of the rubber bands that are still left in the ball.

A pair of needle nose pliers really helps to get most of the rubber out. Use the vise to help spread the golf ball will help to get the hard to reach areas of the golf ball. Once you clean up you golf ball you can start to put add the weight to it.

I used the bb’s we used as kids to weight it down. I am sure that if some one used a heavier metal like lead you could get more weight out of it as desired. If you fill the golf ball to the top with bb’s you will get the weight to about 4 oz for the real golf ball and 5 oz for the practice golf ball. I have no idea why this is so. Both are a good weight for me. Then you need to cover the hole you made so the bb’s don’t fly out as you sling it. I used normal black electrical tape.

You can do a cross pattern to make sure that it did not come lose. You could use duck tape but the electrical tape is about the right width for the golf ball. They do have different color electrical tape in case you don’t want to use black. The instructions will
work for the practice golfs except you don’t have as much work to pull out the center and don’t have to drill into the center because it is so soft.

(Here are the steps for the practice golf balls)


Well there you have it; a simple project to make in a couple minutes of time that is fun to sling.


The first test was a good one. I slung the hollowed out real golf ball several times and retrieved it with no problem. The Golf ball held up with out it coming apart. Even the electrical tape help up for 5-6 throws. I slung it about 100 yards just so I could retrieve the ammo afterwards I didn’t actually hit anything hard like a tree, so it probably wasn’t a true test for the tape. The way I figure if I put some real power on it, I probably won’t be getting the heavier golf ball back. Lobohunter from the forum had a good idea of using practice golf balls. They are a lot cheaper than real golf ball. What I hear from is that they bust on impact. So don’t expect to reuse them. There are two different kinds of practice golf balls. One is like a wiffle ball, and the other one like just like a golf ball. I would use the one that looks like a real golf ball. They are a lot cheaper than buying real golf ball so they are probably the best bet for someone with not a lot of money as they cost only 3 dollars for a dozen instead of 10 to 15 for real golf balls. They don’t feel as durable as the real golf ball, but they will work! The second test with practice golf ball was pretty good. I slung it only 100 yards but I could double or triple that distance with now problem. I did not want to loose it just yet. If a person made a golf ball sling like the one in the articles page you might be able to sling it farther.

Like I said earlier they are heavier, but I think most people will like for it to be on the heavier side. I hope everyone enjoys making the cheap ammo and I hope that I help someone get more involved into the slinging sport.
