Bigleauge,
as others have said, you can get a lots of info on any good search engine. Also sites like www.chuckhawks.com/recoil_table.htm and Haas ammo guide at www.calweb.com/~haas/ammoguide/ could help you too.
Let me also give you a word of caution, you say that you are somewhat new to shooting, so my advice to you would be to find some rifles that you can shoot before you go out and buy one for yourself! Don' t get caught up in the " magnum craze!" Get something that you can shoot ACCURATELY!
Magnums are great! IF you can handle them, but even the 7MM Rem. mag has more recoil than the average shooter will be comfortable with. Good luck!
