Berger Jacket Thickness

Is there a data sheet somewhere that shows the actual jacket thickness of Berger bullets. I'd like to know the thickness of their 6mm hunting and target jackets.

Not that I am aware of. I have been inquiring about the same thing with some of Berger's new hybrid bullets. Berger did respond to my emails but on two occasions did not answer my jacket thickness question for some reason. I ordered the bullets I was inquiring about and I am going to use a dremel tool and slice it in half along with one of my current Berger hunting VLD bullets and compare thicknesses with a micrometer or dial caliper.

I use some of the J4 jackets (Berger) for swaging my own bullets and the ones that I have measured are .012" at the mouth and I think .020-.025" at the base......Rich

Re: Berger Jacket Thickness

I thought they called all their jackets "J4" regardless if it was the thick target jackets or the thinner hunting ones.

They probably do, but I think the ones they sell to the public are the thin ones which used to be target and are now designated hunting. The thick jacket target bullets are probably not sold as jackets only but you would have to call berger to confirm.

Re: Berger Jacket Thickness

J4 is a division of Berger. They produce jackets only, and these are sold to bullet makers. The thickness may be proprietary. Their "hunting" bullets have thinner jackets than "target" bullets, to preclude break up in flight. As far as I know, Sierra is the only other manufacturer of jackets.

It's going to be tough to keep something like this a secret. Anyone can buy them and measure them.
