@bruce mouldsfirst i should qualify why i have a 9.3x64.
having owned a 375 h&h with great satisfaction, i just had to see how claims of the x64 stacked up.
intended targets are donkeys, horses, camels, cattle, and ever hopeful of buffalo, in aust, and even less likely, african game up to and including buffalo.
here in oz, these targets in the desert can require a point blank range trajectory out to 300 yds, and enough killing power when they get there.
i will not abide using firearms that scratch things down, considering this a moral issue.
the 9.3 has proven to be a disappointment gun with nosler partition 286 gn bullets.
however 300 gn swift aframes turned that on its head dramatically.
the next test is 286 aframes vs 300, primarily due to the fact that the lighter bullet can run 150 fps faster at the muzzle, and surprisingly has a higher b.c. than the heavier one.
this will give better velocities at 300 yds for bullet expansion.
the 286 bullet has the same sectional density as the 300 gn 375 bullet, so in a way it is in that class, and ahead of the 270 gn 375.
the 300 gn swifts in stock will be kept for buffalo at closer ranges.
a guy gave me 400 cases necked up to 338 from 8mm rem mag.
these would compare with the 340 weatherby, and possibly beat it if the brass is tougher than norma made 340 brass.
probably great for all the species except buff and possibly cattle, compared to 9.3.
the thinking goes on, but testing has to be done.
