300 wsm for me also.  Was/still em a 7mm fan.  Shot many elk and deer with one.  Bought a Tika in a 300 wsm and fell in love with it.  As I have really bad shoulders, I also (as stated above) can handle the recoil without a brake and it shoots really well.  And as it turns out, the critters hate it as much as they did the 7mm.
