Hmmm .. hadn't seen those before surprisingly. Nice pics. Were they taken by ''The'' Blackhawk .. who is still slowly recovering from that awflu stroke?
had planned on taking some like this myself . may yet do so .... wanting if I can to introduce a smidgeon of light into breech somehow to get a hint of light in the bore.
You can see tho just how excellent finish is in fine detail ... not all guns will let you get this close in without seeing rough edges etc.
