These bullets are 45 caliber, 600 gr and look quite like a Barnes original except the lead exposure is very small and has a tiny hollowpoint in it.

Came with a package, rifle, dies, cases and these bullets.

Anyone knows who makes/made them ?

It might be some of the old Barnes original solids. I have some with a similar looking hole in 510 cal rn solid.

Yup appears you are correct. Probably never shoot any of them but they are neat old things.
