In my first post i was talking about some different rifles . (remember i am a gun baby still wet behind the ears) the 7mm rem mag is what most people suggested that i get. OK>>>>>>> looked for any info that i could find on the net and i couldnt find much on any 7mm. Now i know there is tons of info out there but not sure where to look. any links would be helpful.

Also what is the difference in the 7mm, 7mm rem mag, 7mm ultra mag. Do these rounds require different guns or they ammo description. CRAP i have a lot to learn.
