7mm Wby / 300 Win Mag

[RustyPin]

Does anyone have any info on this Wildcat? This has to be the Hands Down Easiest Wildcat I have ever touched. Forms up Perfect just a hair below the Win Mag Shoulder. I call it my 7 Wby Improved, but I'll bet it's been done thousands of times before.

Since you're calling it a Wheatherby, does it have a double radiused shoulder ?

7mm-Practical / 7mm-300winmag is well known in the long range game.

Yes, it does have some sort of "Double-Radius-ed" Weatherby Shoulder. It's like it takes the 25 degree Shoulder of the 300 Win Mag and turns it into 45 Degree. Simply put it's the 7mm Wby improved & it's considerably shorter than the 7mm/300-Weatherby yet taller at the Shoulder than the standard 7mm Wby without the Long protruding pronounced Neck. The brass goes from standard 2.62 & the Shoulder swallows over .01" in the transfer taking it down to 2.6" or just under. I'm Stoked!

If I maintain the 300 Win Mag Shoulder as much as possible were talking 2.196 Shoulder height, only drawback is the Neck. Where do I find a Reamer for a 7mm Wby with a short .285" Neck
