I second ARIZONA JAKE!
the bullet selected , does 100% of the damage and proper bullet selection goes a long long way towards controlling the type of wound damage,you might want to try BARNES (X) , failsafe, beartooth, or NORTHFORK bullets in the heavier weight ranges and try placing the shot in the lower 1/2 of the chest behind the front leg if possiable where the bullets tend to zip thru the arteries above the heart without hitting bone.
I can diffinately tell you from dressing out several dozens of elk over 33 years that the bullet used has a huge effect on the wound, and useing bullets that expand extremely rapidly agravates the damage if bone is hit, Ive dressed out ELK hit with 7mm mags and 150-160 grain bullets that had far more bloodshot meat that my 250 grain 340 mag normally leaves, its the bullet not the rifle that does 100% of the damage, use a bullet of at least .280 sectional density with a heavy jacket and place your shot correctly and youll have far less bloodshot meat, (BUT BE AWARE that its not at all uncommon for ELK hit with those stronger bullets to run slightly further,yet the exit wounds make the short blood trail, if any easier to follow) again shot placement is extremely important!
