[QUOTE="jrock, post: 1764481, member: 78569"] I was planning to build a 7 RM to do what the OP has planned. Ok, not specifically across a canyon but at 1000 yards for sure. It was to be my 'do-all' rifle and I didn't want a big caliber. However, half way through my research and a 7mm barrel on order, I switched to the 338 NM. If I compared the 338 300 grain projectile with something, it would be Thor's hammer. My build is supper accurate and easy to shoot. However, I wouldn't mind more velocity. I would shoot nothing less than the 7mm 195 Bergers over 3000 fps. That combo looks good on paper. My 338 may appear slow at 2780 fps but the terminal results are unquestionable. If you were talking deer at that distance, I wouldn't hesitate with a 7mm caliber. All atmospherics being the same, the wind drift delta between a 7mm 195 @ 3100 fps and a 338 300 grain at 2800 fps is 4" in favor of the 7mm. Both are hits but you'll get much more life out of the 338. (data from Berger's calculator) [/QUOTE]
