From left to right: Remington Core Lokt, Winchester Super X Power Point, and Federal Powershock. I wanted to see if more/less lead exposed and if a higher/lower copper jacket on the bullet was anything to consider in the better ammo debate. It was also to eliminate the opinions from keyboard wariors, "I read this online multiple times, therefore I need to hunt with the $43/box ammo and the $39/box ammo is just absolute junk!"
I originally bought the .300 win mag for elk and black bear hunting. Then liked it so much I'd rather shoot it than my old 30-06. A lot of people online said that they use them for deer and have had better results with the 180 grain vs the 150 grain ammo. Yes, I do understand that shot placement is far more important than what caliber or ammo you are using.
As for my groupings, they were all so similar that all three rounds would work fine out in the field where my gun wasn't in a stand. So many other factors would make a larger difference.
