Going to start to reload 6mm remington soon I mainly for cout reasons. I was looking at sI sierra gameking 85gr. Which are under $30 per 100 which is in the price range I'm looking for. My question is for shooting deer 200 yards or less with a 85gr bullet does it have some good nock down power when shooting for heart and lungs Or should I get heavier bullet I know it's all about shot placement which is very important to me. First deer I killed with the 6mm was 100 yards away right in the kill zone blew one leg off at the shoulder raped both lungs and slightly grazed the heart but he still ran 400 yards till we got up to him and he was still alive and had to finish him. I was using 100 gr core lokt factory ammo are these game kings a better bullet for taking deer at 200 yards or less
