Cayugad -- thanks. These bullets probably don't have a great BC and are swallowed by the HPH-12 sabots but they work. I'm looking forward to trying the 260 Partitions which would have a higher BC, though I'm not looking forward to the practice session price tag.[]

Next weekend I hope to finally shoot the factory 54 cal. barrel I got with this old Hawken. It's a virgin. [&:]
