I drove over an hour to the range today only to have the 3rd round completely lock up in the chamber. I was using Tubb's finishing ammo. I brought my firearm to a gunsmith and he was able to extract the round. It suffered from an LPS (never fired), and the shoulder was too wide which caused it to seize. The tip of the round is also slightly impacted from chambering. I called Tubbs and they want me to send pics.

According to your link, the much worshiped Hirtenberger uses a "bi-metal" bullet jacket. As in copper plated steel. Oh the horror

The thread I linked to in post #20 above elicited a binary response to my suggestion that this stuff may actually smooth out your barrel: From, "mild steel is too soft to burnish a barrel"; to, "Never shoot steel; why wear out your barrel prematurely?"
