Both are rubbish. Only the .275 Rigby for me.

Have to read the article, but by its title, it sounds like yet ANOTHER .308 vs .30-06 or .222 vs .223 article to me.

Whether A+B is better than B+A is very important.

I do have a preference for a 7x57 or .275 Rigby to the extent, I would never own a 7mm08. ;_

BTW Having lusted over two .275 Rigby's in Darwin at the BGRC informal meeting/show and tell/Marrakai's house dinner, one a Jeffery and the other a Rigby, I hope one oneday enters my gunsafe.
