I have had two model sevens in 7mm-08 and found that 140's worked well in them for all game hunted.I used 140 gr ballistic tips for deer and 140 gr partitions to kill moose and bear.Penetration with the 140 gr partitions was not a problem on moose or bear.I sold one of the guns to a friend who tried loading heavy bullets but found that because of the short action he had to load them too short and they took up so much room in the case that velocities really suffered.
