RE: browning a-bolt caliber???

The 300wsm might be one to look at. It is getting the most play of all the new short magnums (I believe) so will be around for a while.
From reports it has less kick that the 300 win mag and almost as much power.
Lots of people will tell you from their experience that the 7mag is as good as the 300 on elk. I prefer the extra bullet weight and power of the 300. You will have to decide for yourself on that one.
I live in Idaho have shot and seen lots of elk shot and I would buy the 300 wsm if I was deciding today from those choices.
