Short necked .300 Weatherby wildcat?

Found a pile of these at the range. It must be some sort of short necked .300 Weatherby magnum wildcat, right?
The headstamp says "FC 15 300 WIN MAG".



There were also quite a few real .300 Weatherby Magnum cases in the same pile. Looks like someone didn't check their headstamps (or even look at the cartridges they were loading).
Think I can neck size to reload it? ;)

They head space on the belt, so it will chamber and fire. Same with a 7 Rem through an STW, or a 7Rem in a 7 Weatherby. None are a good idea, but I've never heard of anyone getting hurt yet.

WOW the elasticity , Well I can honestly say that I learned something new today... But don't think I will try it though.
 
The pressures are also good. The Weatherby is 65k psi and the Winchester is 62k psi. The larger Weatherby chamber will also work to decrease pressure somewhat.
The belt dimensions between brands of brass can be pretty inconsistent though. I preferred to necksize my .300WM brass after the first firing so it would headspace off of the shoulder after that.
If the belt was a little off, which is likely, the bullet could hit the throat unevenly which, though not catastrophic, can't be good for the rifle if someone did this regularly.

I just thought it was neat and wanted to post it up ;)

Thanks Dog, that's pretty wild to see the results. I don't get out much so this is interesting stuff. :cheers:
 
Hey Dogleg, the 7 RM will not chamber in the 7 Wby chamber but will the other way around. I do this back and forth all the time and when I'm tired of playing with my 7 Wby or I need a few more 7RM cases I just pop them out in the RM chamber. If I'm going the other way I just run the RM cases through the Wby die and Voila, 7 Weatherby..........

Looks kinda like a 308 fired in an '06 chamber...........no safety issues, just a waste of good brass...........guess he was too cheap to buy the Weatherby ammo and besides his buddy told him "Ah, Weatherby...Winchester...Whatever...they're all the same anyway." I would be willing to bet that he is going to go hunting with that rifle and ammo and doesn't know any different..........."Hell, it's good I hit the target all three times, she's dead nuts let's go huntin'"

The fact that there are more than one such case on the ground, tells me the shooter ain't got a clue anything is wrong. "Yep, they always look that way when I shoot 'em, but I got my moose at 900 yards last year with it, right in the eye........"

The .300 Weatherby was just a .300 H&H fired in a Weatherby chamber until they got around to having brass/ammo made. Same with the .375 Weatherby, and then there's all those Ackley improved cartridges that shoot factory ammo until you have enough brass to load up the newly formed cases. Although its a bit different the most common way to get .458 Lott brass is to neck up .375 H&H to .458 and just shoot it. The pressure finishes "building" it. I also did the opposite by necking down .300 H&H to 7mm and firing it in an STW. There's all sorts of useful ways to put the mallable nature of brass to use, I made a pile of .458 brass by sticking 12grains of Unique in .338 Win and .300 Win brass, topping it up with Cream of Wheat, plugging the neck with soap and pulling the trigger. The pressure blows the shoulder out straight on both, but the .300 brass needs a little trimming. Handy when the right brass is hard or impossible to get and factory ammo varies from 100 to 200 a box.
 
I had the pleasure of watching someone making cases just like that. He thought that a 300mag was a 300 mag, he had no idea that there were different versions, so he just bought the cheapest ammunition that they had in the store. He was quite upset when I explained the difference to him, and he realized that he would have to start buying the more expensive 300WBY loads.

I also watched the result of someone firing 7mmremmag ammunition in a 300winmag. He fired seven shots before my friend came over and mentioned that the shots sounded odd to him. When we looked at the fired cases, it was obvious that there was a problem, and when I mentioned that he was firing 7mmremmag ammunition in his 300winmag, he looked at the ammunition box, then he turned red , packed up his gear , and left the range.

Correct me if I'm wrong but isn't the 375 ruger a non belted case? How is it possible to make 375 ruger brass from 300 win mag brass?[/QUOTE]


65,000 PSI..........that's how............First you take an ordinary loaded 300 Winchester Magnum cartridge, chamber it in a rifle chambered for the 375 Ruger cartridge and pull the trigger.............voila, 375 Ruger brass, everytime.
