Following advise from the forum almost 2 years ago (it took that long to get a license for the 300rum) I made my first kill 1 week ago with the 300rum. Area was eastern cape, South Africa with exceptionally tough shooting conditions. Wind howled non stop for 5 days, over open plains with not much cover to stalk closer.
Got this mature bull black Wildebeest with a 220gr smk. Rifle was standard Rem sendero and IOR Valdada scope. Perfect performance from the smk. Although no large bones were hit, only ribs on entry and exit, it penetrated through heart and lungs leaving about a dollar sized exit wound. Tough animals that they are, he ran for about 60 yards before collapsing. (That with the shot destroying the bottom half of his heart).
The 300rum and smk's did a perfect job. Just the medicine for open plains shooting. Good advise from the forum. Thanks.
