Hope this helps,
Mr. Hummel presently runs the custom order desk at Hornady, and is a champion target shooter. Mr. Dave Kiff, of Pacific Tool and Gauge referred me to him. Hornady had to get the legalities correct, or be sued ala Rick Jamison vs. Winchester. The orig. Newtons had really thick case walls to do the 1912 expansion trick. The later Schulers used this same case wall thickness, but in a proper German chamber. The new Ruger Basics are the same diameter as the orig. Newton chamber, but too large for the derivative Schulers. This Ruger is one tough customer. The extractor rim takes a herky regimen, in the foming stages, without ripping out of my RCBS shellholder. I guess the real question about the 38 and 40 Newtons, is why bother, when the 375 and 416 Rugers are available off the shelves. Right now, everyone and his uncle is necking the 375 Ruger down. My effort wasn't to grab more power, but just to get an American case, that follows along with the general 8 x 68 Schuler, and feeds really smoothly through old mil. M98 Mausers, with the old stepped barrels. Interestingly, there's a baker's dozen of these 8 x 416 Ruger reamers, that Dave has sent to South Africa, but so far no one has tried what I'm up to. All three of these, the 8 x 06, the 8 x 338 Win., and my nascent wildcat, will get around the 150 gr. Hornady jumping over the long leade of the military 8 x 57 chambers. I feel that the PMM, or 8 x 338, is still the better bet, with the lighter bullets. It's only with the long brass Barnes, and the heaviest jacketed lead bullets , that my new 'cat' is designed to fill an economical niche.
