.358

As you probably know there was a problem with the firing pin breaking with the pin jamming protruded resulting in firing as the bolt closed on the new round. I'm not sure if this was corrected in later models or not. A recall/retrofit was done. Was the rifle you're looking at retrofitted with the new pin? If not, you would want to have it done assuming it can still be. Others better informed than I could be more specific. gg.
