Have you ever shot em ruddy?

Might want to think about that before going to Africa. Just reading about em isn't going to get the job done.
No offense, but with your original post, its very hard for me to imagine you reload or ever had. Hardcore reloaders on here would probably agree.
I have never had a 300win mag or weatherby that could close to the performance of a 300RUM. I have yet to ever see a 300win mag come close to 3350fps with 180gr bullet.
