About .300 Win Mag

.300 Win Mag is the default American magnum for big game at distance — hard-hitting, hard-recoiling, and expensive to feed. Premium hunting loads run several dollars a round, which makes it a caliber where shopping the per-round price saves real money.

Common bullet weights run 150, 180, 200 grain.
