Nick's 338 even gives the 340 Weatherby a run for its money but it was built on a magnum length action and long throated so he could pile on the coal.
There's a lot of cartridges out there that can be given a boost with proper reloading techniques and a bit of experience/ experimenting.
Nick proved that over the years. Even his favourite 257 Roberts when loaded to its potential gave the 25-06 a run. Nick and Les Bowman I think it was tried to convince Remington to use their loads but as usual Remington wouldn't have a bar of it.
Getting 3,000 fps with a 150grainer in a 30-06 is easy now and gives the 30 magnums a run but then again the 308win with a healthy ( but safe) does of CFE223 will easily give a 150 grain bullet in excess of 2,900 fps from a 22" tube.
There's a lot can be done now with some of the newer powders around. Just a pity we can't get a lot of them in Australia.
