300 WM altered.

[Jarlath]

Anyone heard of people making wildcats from .300 WM brass?

I picked up a few dozen new brass at a sale a few years back and I am finally getting around to reloading them (now at over 500 empty 300WM brass plus the 2-300 factory).

Out of the 80 or so brass, one box of 20 was necked down to roughy .270

and super fugly shoulders.

Anyone have any finished images or data on these wildcat cartridges?

Just about everything has been necke dup and down on the 300WM or similar.

Sounds to me like someone was trying to produce 270 Weatherby cases.

 

[prosper]

maybe someone tried forming it into 270 Weatherby brass. That would account for the neck and shoulder

Double radius shoulder? If so it was probably for a .270 Weatherby the granddaddy of the entire Weatherby line of cartridges. .

hmmm, maybe they tried to make, oh what is it called..270 Weatherby?

 

[Jarlath]

Laugh. I dunno anything about Weatherby calibres. I just know that the head stamp says .300 Win Mag and instead of a nice sharp shoulder, these has high radius almost squared shoulders with a neck sized at .270

I'll try and get an image or three.

I looked up the .270 Weatherby and yup, that does look like the result. Fugly though...

Never even crossed my mind that type of conversion, actual .270 Wthby brass is expensive I take it?

Not overly costly but availability may be limited in some areas. Case conversion from one cartridge to another is a natural extension of reloading where one uses what is on hand to fill a need.

Bah. as if sorting by headstamp wasn't enough effort....

There is also the 7mm-300 Win Mag wildcat, variously known as a 7mm Yukon or the 7x66 Randall/Argentine. But with a 270 neck and the radiused shoulders, yeah, someone was making 270 Wby brass. - dan
