???= not a clue on the first one. I couldn't even venture a guess. My thoughts, by looking at it, is that it is some sort of wildcat 300 win mag brass necked down to 6 or 6.5mm. For the life of me, I can't think of a belted cartridge that small of a caliber. I know weatherby make some but all of the weatherby necks are more severe
The only one you couldn't figure out is the 6.5 Rem mag. This cartridge was developed by simply necking down the .350 Rem mag. It was offered initially in the old Rem mod 600 & 660 carbines. They were also reintroduced in the updated Rem mod 673. These two cartridges, the .350 & 6.5 Rem mags are of course the very first of the short mags and never were referred to as such.
Dirty pool! First thing I though was class of cartridge's on the same case. I figured the 57mm case was a shoo in. The 6.5x55 and 7x57 are two of my favorite cartridges! That one with the belt really threw mw again because I'm thinking, metric equals European.
So what factory cases are made on the 57mm case? The one's I know of are the 5.6x57, 6mm Rem., 6.5x57, 7x57, and 8x57. There any more? That is a great case!
Hey Don, the belt didn't tip you off on the first cartridge? I agree that the 57 cartridge does have some great cartridges in it's family line. And YOU of course noticed the 6.5x55 sitting up there loud and proud. That was the only one I recognized and was the starting point for guessing the rest (except that pesky little bugger 6.5 rem mag.)
Tndeerhunter, that 6.5 rem mag looks like an excellent round. It is one I have never come across before and I have had my hands on a lot of different rifles. Is it still around or fallen to the way side? It seems like America doesn't like the metric rounds. I have a 6mm rem that is as good or better than the 243 but the 243 took off while the 6mm sits there.
I like the 6.5 RM, but I've not yet shot anything with it, besides paper (killed the heck out of that tho!). It's a ballistic twin to the newer 6.5/.284 and the cases are even almost exactly the same capacity actually. I was actually looking for a donor rifle to build a 6.5/.284 when I found a NIB 673 in 6.5RM so I simply bought it. Heck I only paid about $400 for it, NIB. With 120gr loads it's a screamer claiming 3200+ FPS. I have a couple of boxes of the 120s left and a box of 140gr NP from Conley. I figure that to be an excellent round should I ever take it out west. I may just give it a sit from a local stand I have here that overlooks a couple of long fields and has honest 300 yd possibilities. You know, so many guns, so little time...:D
Don't assume that when fall comes, or hunting season, that the big bucks, and big bulls leave. Whitetail deer bucks especially, simply hide. And they hide very well. Mule deer bucks may leave a little. Bull elk may leave, but don't assume they do. Don't assume any of them do. I mean - where would they leave to? (Just another place where, for the most part, they would be hunted.) These big animals have the ability to hide in very small, very obscure places. So, embrace the fact (...
