I've shot and like a lot of smaller cals like 6.5 and 270's and killed a lot of stuff a long ways of with them especially elk BUT I pass a LOT of shots and I pass a lot of days I just can't shoot in, in the timber you'd better be spot on as well because I've seen elk pack themselves a LONG ways with just a little hole in the wrong spot. I personally loath the 7 Mag, I've seen more **** poor performance from it than any other single round, I get many guys rebuilding them into 300's and I get many built into 270 WSM's or 6.5 SS or SAUMs, it's thee more common chambering on the used shelf at the gun shop and they don't even stock anything new in 7 Mag, that speaks volumes in a little town in MT where all of the world comes to shoot elk!
Shooting a 300 is just as easy if built properly as anything else, it maybe easier IMO because your able to run more BC in the wind and they make wind calls much more forgiving. After shooting 6.5's a lot it takes me a little bit to stop over correcting on my wind calls when going to a 30 cal. Of all the guns I build the 300 by FAR is the most requested!!
