[Packer Backer 57]

I attended a gun auction and picked up what was listed as a 223 Winchester bolt action. The gun is in decent shape but is actually a 240 Gibbs. I have been having the most difficult time finding much information on this rifle.

Any information on it would be helpful. Particularly if you have a reloading manual with info on how to convert brass and tips on loading new rounds. Unfortunately, given the scarcity of shooters, I will have to make my own ammo.

I will see if I can post a pic of the rifle.

Thanks!
