I don't have a 7mm. Have had a 270 from the get go and never saw or found a need for a 7mm (Until and if I shoot out the barrel of my 270). However I have looked at the 7mm and decided that if I ever picked up a 7mm it would be the 7X64. The 7X57 and 280AI were the other close contenders. But a 275Rigby is always on the cards
