Live and learn.
The crucial info is that it is intended to work out of short action.
There are some cartridges that will give you an additional 150 fps with 5 more grains of powder, but I suppose that this is not one of them.
The .338/9.3 probably is the equal of the 9.3 X 64 but 338 brass is handy, and it's different, and isn't that what wildcatting is all about?
Slap a new barrel on my Ruger 77 LA, and away we go.
Thanks for the info!
