You know one of my best customers shares this view. He uses a 7 Mag for just about everything. It its too big to kill with a 7 Mag, he goes up to the .338 Win. I tend to like the .270, think the 7 Mag is in about the sameperformance class- and have a hard time thinking of a North American situation where a .300 Winchester with a 200 gr. Nosler partition would be too light. From there, I would go up to the .416 Rem Mag.
