Joel.it will probably be Partitions, or basic 180 grain Hornadys.Im hunting a cow for meat and they are roughly the size of a cow elk...and I know either bullet will work.
You'll be fine with the '06 as long as your outfitter is ok with you using it. Some require a 300 win mag minimum for the kevlar penetration. Fwiw, I used a 300 win mag with 165 gr Barnes and got a full pass through on a 575lb bull. He piled up in about 80 yards. The guys I used thought the 30-06 was fine with monos.
