Any shooter owning a drill press can have the vise grip a shell holder and the right sized drill can be installed in the chuck, the travel of the chuck downwards can be controlled to a stop at the right depth and you can hollowpoint your lead bullets in your live ammo zip, zip, zip

Also in my tool cabinet there is a special drill set with a adjustable stop collar on it that is used to counter sink screw holes for fine furniture and it has bits like minature screw diameters to take out wood so there is less pressure to insert a screw and stop any chance of the fine wood splitting when the real screw is installed.

Hope this helps

I made one to fit in the top of the Dillon 550.

You use the crimp stage to hold the bullet. You put the handle in the down position so that the bullet is sticking up in the die.

I use a battery operated drill with a bell radiused center drill. The centerdrill has a stop on it that is adjsutable for the depth of the hollowpoint. I made a bronze bushing that fits in the top of the crimp die to align the center drill.

When done it looks like a factory hollowpoint and acts about the same. When shot into gallon jugs or water, it looks no different and expands rather nicely.


Good for you Watchman A handy fellow.

Forster makes a commercial hollow pointer that is used with their case trimmer. it works well.

FYI
I had one that fit my RCBS case trimmer, can't remember the brand, maybe RCBS?

It worked really well but it was a slow process and not worth the trouble IMO

From someone who has done this more than a few times:

I found that if you turn the bullet instead of the drill, the hollow point is more centered in the bullet and more uniform.

There are two ways to do this:

1. in a drill press - gently chuck the bullet (you can use an old case to hold the bullet to prevent marring) and lower it onto a 1/4 inch CENTER DRILL (a lathe tool for boring a counter sunk hole for a center to fit) stopping at the point where the 60 degree cone begins to cut. (the drill has a small pilot drill that is ground into the 1/4 inch bit and the transition is a 60 degree cone) This will give the HP a cylindrical cavity with a bell at the nose. (to aid rapid expansion)

2. do the same thing in a lathe that you do with the drill press. The results are a bit better and the hole a little smaller.

I have used the trimmer style with poor results where accuracy was concerned - the lathe turned bullets have no problems with accuracy.
