The breech from the borerifles are just impressive.

Good luck with that 8bore. 960grain roundball fueled by 10 drams will get near 1700 ft/sec if it like a Swiss 1,5 powder.

To begin with I felt confident to cock both hammers of my 10 bore...but the thought has reconsidered me to cock one hammer at the time. Launching 20 drams 2000grain conicals in a 14ibs rifle will send the groundcontrol into orbit with no soft controlled landing.

Always wanted an 8bore to shoot the 1200-1300grain conicals. The bore rifles are amazing and impressive.
