A 320Gr Woodleigh cupped point solid in 9.3 far surpasses the standard 270 or 300 gr 375 in penetration and effect.
Good every once in a while, there's something worthwhile

Thanks, WaltTwoRivers wrote:No question, the .375 H&H is a great cartridge. However......the claim that the .375 will shoot every weight bullet to the same point of aim (unlike rifles chambered for other rounds) was made by H&H solely for the flanged version, and doubles. And different ballistics from the belted case. None the less, every idiot American gun writer writing about the .375 will repeat this, claiming that his .375 (if indeed he has one) will shoot all bullet weights, at velocities quite different from the original ones, into the same group. Regardless of caliber, some rifles can and will group different bullet weights at different velocities together, others won't. The stiffer the barrel, the more likely. There is nothing magic about the .375 H&H. Neither my Winchester M70, my Brno, nor my Ross M1910 straight-pull in .375 H&H will "shoot all bullet weights into the same group". Unless you think that 6" is an acceptable group at 100 yds. Though it would be for a double shot over open sights at 80 yds with different bullet weights.
The paragraph dealing with the 9.3x64 is pure hogwash.
Why .275 and not just 7x57 Mauser? The Boers used that one. Painful memories.
The difference between the .270 WCF and the 7x57? 200 feet per second. Almost none when loaded to the same pressure.
IOF quotes 1975 fps for the .315. The original Austrian, and E-K, was 2025 fps or so, from a longer barrel. When handloading, 2200 fps is easily possible with the 244 grain bullet.
I have it on good authority-Mine- that a 223 would group 62-63gr FMJ at 100m about 1/2 inch, and throw 75 gr Amax all over the target.
That part about shooting all weights at same POI? certainly deserves to be laid to ungracious rest.
Pity about the 315 doing1915fps, if only it was a wee bit more, like my fantasy 2200, a goodly thump at 2600fpe would be more desirable.
