If you're loading the Flex-tip or Mono-flex, you'll need the shorter Hornady brass and likely the Hornady dies so the tips aren't smushed when seating.
I really like the Mono-flex.
Of the conventional bullets, I'd be happy for the rest of my days with the 300gr Speer.
They shoot well, don't over expand like some other 300gr and recoil is less than a 400gr.

You will remember a curve of your wagon track in the grass of the plain like the features of a friend."
