I'm looking for a good round for Ga whitetails for those of you who don't know 100-200 pounds. I'm shooting a 300WSM, I would prefer to stick with a 150 grain. I shot a deer last year that never bled only found by luck. This deer was dead center directly behind the shoulder. I had a similar problem this afternoon only I didn't find this deer. I know for a fact it was but there was no blood hair lung particles nothing. The deer last year was shot with a ballistic silver tip. Just wondering if there is something better.
