Jabali, I've shot a number of .303 bullets into my test media. No hocuspokus. It has a good overall reputation because it is a good caliber. Light recoil, good killing power. A 200+ grain 30-ish caliber bullet jogging along at 2000+ fps has the makings of a good killer of game to the elk/kudu/zebra size at moderate ranges.

Oh, yeah, this has been proven thousands of times in the field for a hundred years!

Seems sort of silly to think that somebody might have a problem with that concept.

The .303 is essentially quite similar to the .308 Win and .300 Savage which is to say it is a good round for taking lots of different game.
