They were shot in a .300 Weatherby. I made this mistake by shooting some 7 mm Remington magnum cases in my .300 Weatherby through a ammunition confusion situation. They all headspace on the belt and therefore will fire in each other's chambers. There was no problem chambering these because the 7 mm bullets will fit right into the 30 caliber bore. Really makes you look at your whole cards.I was at a club for meeting yesterday and found these 4 cases on bench. They are FC 300WM but what happened to the neck of this brass? I think they were shot in something other than a 300WM like a 300Wby? Thoughts?
Yup, the belt holds them in place.Odd. I wouldn't think it would headspace enough to fire. I definitely wouldn't think a 7R would fire in a 300WM chamber. Or is it headspacing off the belt?
That's kind of scary. You would think one would be wondering why the cartridge in hand was an inch longer than "normal" and grew a belt. I guess these guys just buy whatever their buddies tell them too and somehow get to the hunt without really having any idea what they are doing.It's shocking how common this is. Back when I guided we would always take guys out the day before their hunt started to check zero and kinda get a feel for how each guy could shoot.
I bet 10% or more of guys had the wrong ammo. 300's of all different flavors were probably the most confused then anything Weatherby was bad also.
The worst one I remember was a watching a 180" muley slip through our fingers as a guy tried to muscle a 300 wby cartridge into a 300 wsm. He had slipped out with his buddys ammo that morning.
FOUR TIMES!!Mind boggling that someone would try to shoot them in wrong chamber.
