The .280 Remington and Nosler

To say that Nosler uses the 280 caliber for ALL their 7mm bullet testings is a tall order. In addition to that, Ken Waters whom I have a lot of respect for as a gun writer and a hunter once did an experiment with the 280 for which the write up is attached in the second picture.  Many European hunters use its twin brother; the 7x64 Brenneke and I believe John Nosler's personal favorite has always been the 280 Rem, as well Jim Carmichael's personal favorite. It is an absolute hand loader's dream but good factory loads are still available.
