I won't use the 100 gr gamekings again. I shot them in a savage 99 over about 40 grs of 4350. It was bad 6mm in dime out through about 24 " of mule deer. It took 3 shots and she ran about 80 yards up hill. All 3 passed through lungs and within 1-3" of the heart. My oldest boy quit hunting after that hunt too.
