Weibel mentions building a "Nitro Express"on a Mauser 98. I asked him to specify it's purpose but he did not respond.I therefore assume he is referring to a heavy hitter.
The 9.3x62, 9.3x66, 9.3x64,.375 Ruger? No need to complicate things. Factory cartridges cover every
aspect of traditional hunting, target and long range.
I cannot think of any hunting factory cartridge from .17-.423 Cal that can be substantially improved by a Wildcat.
I would not want to try to sell or trade a .375 Wildcat (or any other) in my neck of the woods.
Tony of Tradex in Ontario had a custom built 9.3/.338 Lapua and paid $700 for the Dies and $300 for a reamer. When I asked him, why not use a .375 RUM or reduced load in a .378 WBY he answered I like the 9.3mm. Now he's had his fun he is having a hard time selling it. I see it at every gun show.To each his own.
