Based on a modified .378 Weatherby Case it REALY gets 2845fps. using their own 350grs. FMJ Bullet.
Yes, and belive it or not, it will stay supersonic at about 1600 Meters.....

I don´t know what someone is doing with some "real accomplishment" as they describe it....

Help needed......

The 338WTF? Or the 338Why?.

What is the case head diameter?
Is it comparable to the 375 Chey-Tac?

As far as you can belive the Press its based on the .500 Jeff Case....so nearly a .338LM Head diam.

How soon before one of these guns is converted to 500 Jeffrey?! It’s already got all the feeding kinks hopefully worked out.

Google is your friend: https://bobp.cip-bobp.org/uplo...wiss-p-180302-en.pdf

Compare to .338 Lapua Magnum: https://bobp.cip-bobp.org/uplo...338-lapua-mag-en.pdf

This is exciting to have a new source of brass for wildcatting and for making 500 Jeffery cases. If I read this correctly, the rim is larger at .588” vs .575” of the Jeffery so a Rigby or Weatherby bolt could be used.

This needs a new wildcat idea...
550 Swiss/Jeffery! It would be a 400 Whelen like shoulder. Maybe 550 Fondue is a better name.
