It does have a slightly larger case and uses more powder (2 important criteria) to get the same results, thus, it's popularity in the USA.
I've had a couple now and they were OK. Last one was a Browning A Something. I bought it due to the 26" bl. mostly and wanted a rifle
to play at 1,000 meters at our Blackwater range. That range is now 1,400 meters. It was so easy to heart shoot the buffalo, I lost interest and sold it.
Maybe I need a Creedmoor?
