I now use a 7mmstw for all my deer,antelope and sheep hunting.I have also used the 257wby and 7mm mag as well as the 7mm-08 and 243.I use 140gr ballistic tips in the stw and use only lung shots.As a result no deer has ever made 50 yards after being hit and most drop on the spot.As far as meat damage I lose a rib or two on each side which amounts to very little meat.The main reason for my choice of cartridges is that I hunt open fields and mountains and ranges can be much further than for the average hunter.The flat trajectory and less wind deflection of the stw results in more precise bullet placement that results in quicker ,cleaner kills.
