Two bullets I really like in my Whelen are the 200 gr Accubond and 200 gr TTSX, in your model 700 350 Rem Mag the 200 gr Accubond will be too long but you should be fine with the TTSX. Two others I would look at would be a 225 gr Partition which has also done well for bears here and I hear lots of great things about the 225 gr Woodleigh's both RN's and Protected Point's.
I’ve got the 180 TTSX’s loaded up to around 2875 in my 350 Rem Mag. It’s about as long as I’d want in that case in a SA 700. Saying that, there isn’t much I wouldn’t hunt with that combo either.
