I believe the Gatlings were in .45-70. The ammo looked right, and it was the common caliber for the guns in that era. It is Black Hills ammo, a couple very clear shots of the ammo boxes.
I think (don't know for sure, but it seems reasonable) that the exotic firearms are loaned to the show by collectors / dealers. Last season, a pair of Tommyguns were in one of the challenges. Where else could they come from but a well heeled collector or a machinegun dealer?
The T&E mechanism on the Gatlings was adequate, and provided a basis for later designs. I loved the one comment about how they were the "steampunk" of machineguns!
The red team is getting hammered, and team "cohesion" is suffering, evidenced by the latest elimination round. The early decision to vote for the lowest team challenge performers was not held to. Instead, the push was for trying to rid the team of who was felt to be "weak", to increase their odds later on. Bad move, IMHO, they are forgetting that eventually, there will be NO teams, and it will be all individual vs individual.
Looking at next weeks previews, we are going to veer off into the thrown weapons again, not my personal favorite, and something that I feel doesn't really fit with a show named Top SHOT. Oh well. Can't wait to see what other unusual challenges and guns they get back to the week after.
I think bows are ok, you shoot a bow. You even shoot a slingshot or blowgun. You don't shoot a knife or tommyhawk.
One thing I would like to see is a challenge where they either get to use their personal firearms, and/or one where each competitor picks one from a selection to use for that challenge, then cannot use that choice for any others.
There are lots of things I'd love to see them do, (which they likely won't), but so far, I rate this season better for the lower levels of drama, and fair for the challenges. Hope it improves. Love seeing lots of non-current arms. Puts a real challenge out there, especially for the younger shooters. Kind of helps level the playing field some, since the younger shooters may be a bit better shape physically, but are not as likely to have much experience with the older era weapons.
