Casting lead in copper jackets

[myrockfight]

I was thinking about how most indoor ranges won't let you use cast bullet reloads.

I was wondering why a copper jacket couldn't be placed in a bullet mold before molten lead is poured in so a jacketed round could be created after doing so.

Is this possible? Has it been tried before? How do the manufacturers make their jacketed rounds?

I think jacket separation might be an issue when you fired the rounds if the copper didn't bind well with the lead.

BTW- this is just me thinking out loud. I don't even own a bullet mold or a mini-kiln to heat the lead. So you don't have to worry about me doing this. Someone else...maybe

There's a company that offers a swager that makes jackets from spent .22 shells.

Pretty slick.

Manufactures use swaging dies to make cup & core bullets.
Or electroplating on most of the clean range encapsulated bullets.

With the ever increasing cost of copper, and especially gas checks for cast bullets, I doubt you could buy full pre-formed jackets and do it economically.

A bullet jacket without the core would require most of the same manufacturing steps as making the same bullet shape with the lead core in place.

But due to the limited number of customers who would buy them, I'd guess the empty jackets would sell for far more then completed jacketed bullets due to limited demand jacking the price up.

"HOT-COR bullets are the heart of the Speer line. This bullet is manufactured by pouring the lead alloy core into the gilding metal bullet jacket in liquid form at 900 F degrees. Speer claims that this reduces the possibility of core slippage during expansion. A tapered profile jacket and the specific lead alloy of the core control expansion. Speer recommends their Hot-Cor bullets for animals at the upper end of a given rifle cartridge's capability, which includes all CXP2 and CXP3 game in appropriate bullet weights and calibers."
