I currently use 175gr Sierra game kings with a velocity of 2850 ft/sec.
Does this sound reasonable?
Hi again Xshock2,
Sierra jacketed soft point bullets are typically VERY accurate, in most all rifles, chambered in the calibers that these bullets are made in.
I am quite fond of Sierra JSP bullets, especially their flat base spitzers, for what they were designed (long shots at vermin and N. American deer/pronghorn/wild sheep, mountain goat, caribou, etc.)
Yours truly is a rifle enthusiast (and hunting is my excuse to mess around with rifles, bullets, scopes and so-forth).
Therefore, I have tried many brands and configurations of bullets/powder/primer combinations, etc., etc.
I'm officially an old geezer now and one of many lessons I've learned from hand loading and shooting is that; Sierra old fashioned flat based hunting bullets consistently group tighter than their boat tail so called "target grade" bullets, in each and every rifle that I have tried all the above in - go figure.
Be that as it may, no matter how excellent in the accuracy category that Sierra bullets most certainly are, I would not choose them for shooting large African antelope at close range with your 7mm magnum.
African animals are not bullet proof, just perhaps a slight bit more "impact resistant".
Might be due to tens of thousands of years with abundant apex predators, constantly trying to pull them down.
More than just perhaps, it must be at least in part due to; many African species having their heart and lungs located securely far forward/between their shoulder bones, instead of somewhat less securely located, behind their shoulder bones - such as with the antlered deer family which, many of us are so familiar.
Therefore, I whip a dead horse here by saying that for heavy African antelopes and zebra as well ("the armored car of plains game"), especially at close range, with smallish/high velocity calibers, such as the various 7 millimeters, you will be stacking the deck in your favor by using the 175 grain Swift A-Frame in Africa.
Cheerio,
Velo Dog
PS:
Again, with the right bullet in the right spot, the 7mm is an adequate cartridge for so called "plains game" but, just keep messing around in this forum and eventually the voices in your head will become more and more seductive toward you "needing" a .375 H&H, heh heh heh.
