From what I've heard, not just anybody will chamber the STW cartridges in the TC, because the chamber reaches out too far into where the barrel starts to contour down. This guy found someone who'd do it, and from the reports was just shooting his standard hunting loads, after the season. 110grn accubond over 80+something grains of powder.
You can see in the split in the barrel, just how long the chanber is.
Could you imagine if this happened while he was out on stand, or in the back country? He's lucky he's not blind.
The Doctor said I should drink more whiskey. Also, I'm calling myself 'The Doctor' now.
