remington 722 question

[gumpokc]

OK i know the basic history on the 721/722/700 line, but can anyone point out any "major" differences between the 700 and the 722?

Was looking over grandad's rifle, giving it a periodic cleaning and rubdown. rem 722 .300 savage serial # 171xxx and just got curious about it.

from what i've been told, basically the 721 was the long action. 722 was the short action, and the 700 was a much nicer cross of both that came along much later.
