Hi Igorrock:

Well...your idea is good...but its too late. I already have the cases being stamped "9.3x64 Newton"
and I wanted to have the name "Newton" on the case to give Mr. Newton the credit as its derived from
his Newton case...plus the dies are already stamped "9.3x64 Newton"..so like is said...its "water over the dam" now, or too late! Anyway, you ignore that "9.3" is metric anyway, if it were English
units, it would be .366 bore...
Still I think its the Best 9.3 cartridge...not extreme, yet probably the most powerful.
I once had a write up on an Internet site of having developed Newton Big Bore cartridge wildcats...but the site was removed later...it had photos & descriptions of my 9.3, .416 & .458
Newtons. If the site comes back...I'll forward you the link.
In any case...it was a good idea...as the big body Newton design lends itself to big bore
cartridges, yet efficient modern design.
Mostly...I didn't have a point to prove...just wanted to satisfy my own curiosity & am happy that I did it, as they all turned out very well!
I have some standard factory newton cartridges...the .256 Newton, .30 Newton, .35 Newton as well as the Big bore wildcats...9.3, .416 & .458 Newton wildcats.

Best Regards,

Tom
