Notched jackets

[MIBullets]

I am making 358 caliber bullets using copper tubing. I was wondering if anyone has come up with a way to notch the mouth of the jacket to make the bullet expand a little quicker on impact?

Depends on how much tooling you have. It can be done on a lathe with a carbide bit set 45deg and the jacket locked in position (not turning). In a mill the same way (bit not turning). Mount a dremmel with a tiny carbide ball mill in an arbor type setup. etc...

Corbin makes a SDD-1-S jacket serrate/draw die for that job.

Reed1911, I don't have a lot of tooling. I do have a dremel tool, but not a good way to hold the jacket that I can think of. Any ideas?


LeadPot, I have looked at Corbin's SDD-1-S and SDD-2-S. I like the second one better because you can control how far down the jacket you serrate it. I just can't spend the $250 - $300 to do that. It would be nice to build one though.

Well if you dont have the tooling it would be a little harder to make a tool.
This might put a idea in your head.
Use a inexpensive Lee bullet lube size die and make your own draw die and serrating tool

Well, you can use a collet which would be best, if you don't have one and don't care to buy or make one I'd think that dental adhesive may do the trick. For a cheap collet system, most economy tool places sell the alumiunim jaws for vices, if you get a thick enough set and drill the proper sized hole you should be able to use that as a split ring fixture. Slow I know but it would allow you to make a few and see how they do.

Yes a collet bullet puller would work, then all you need is the Lee sizing die ram and use an old wood chisel and put a few burs on the punch end and run it in the jacket that held by the collet.

But it's a lot less work yo just use a thin jacket and expose a little more lead and hollow point it.
All the expansion you need.

Good idea, I never thought about the bullet puller, ready made collet for you right there.

Aaaaaaaa so; now the light bulbs are turning on

I have a full shop and compliment of more tools than I can list, but I like to think simple and easy for the guys out there with ideas they want to try and easy ways to do them. Better than poo-poo'ing the idea or telling to to go spend 1000.00 in tooling to do it right.

My Sheldon Lathe and mill gets used more for gun related things then anything else.
But I agree with you Reed

[MIBullets]

Thanks guys! I have to do some shopping and see what I can put together.

I got one from RCE a few years ago in .308 it works very well. It is for sale also. $100   Mike

I dont have any need for one.
I have a complete set of dies for the .308 rebated bt.
Put it up in the sell & swap maybe some one will trade with you.
