silly me - I'd forgotten (or didn't know) the current pressure levels of that long tapered around, the .375H&H(I'm embarrased). If one form was to give trouble in heat, it's a long heavy tapered round, just as the H&H. Get the pressures up a bit and bolt thrust locks things up. Since that doesn't EVER seem to be a problem with the H&H, why would it be a problem with a ctg. that has a much better 'designed' shape for handling presssure?
; Everypone who shoots Ackley Imp. ctgs. knows the ease of extraction with pressures that lock up actions with more tapered cases. The straighter the sides of the case, the better it handles high pressure.
; Since the .375 Ruger has greater capacity, it's ballistics will be alightly faster at the same pressure, with the same bullet weight. Because the Ruger has a better designed ctg., it will handle any presssure hikes even better than the H&H.
: A ctg's future life depends on the number of different rifle mfg'rs who chamber it. A ctg. needs a variety of rifles for a basis for acceptability by the public. I think the .375 was a great idea for a fctory round, but whether it survives or not, depends on other makers of rifles.
