Copper jackets

[abunaitoo]

I think I asked about these before, but I can't find the post, or my notes on it.
I have a bunch of copper jackets.
I think their called jackets.
They are....
.523 tall
.351 OD
.328 ID
What caliber would these be used for????
Attachment 177694

[R.Ph. 380]

Either .356 or 38/357

Sent from here to there by me using smoke signals

Typically 38 caliber pistol bullets ....357. D

That's what I thought.
Don't know anything about swaging.
I guess it's smaller so when swagged, it expands to the correct size.
What diameter would the core be????
Would it be as close to the ID as possible????

[uncle dino]

.Typically that jacket will take a .312 core. that is not a rule, just a common lead wire size..any core up to id of jacket will work. D

Thanks for the help.
I'll read some of the Stickys and decide if I want to try it.

Where does everyone get their copper strip for making jackets?

Anyone know a better/cheaper place to buy copper strip?

Another possibility I am debating is http://www.supplyhouse.com/Elkhart-30626-1-2-Copper-Cap
what would one of the experienced swagers say?

I bought myself a small guillotine that will take 12" wide sheets and use it to cut 1" wide strips, its a little more to do but if I buy enough 2x1 sheets it becomes very cost effective .
