Thanks for all the input.

I liked the 7mm suggestions but I think my 300 WSM will cover anything the 7mm will. I just kept feeling that the true void was a medium bore caliber and since the action I have is a 30-06, the 35 Whelen was a perfect choice for my needs. I don't need a super duper match barrel so I ordered the E.R. Shaw kit from Midway.
