Questions & Answers
Will these be a good home defense round? Been looking for 110 grain to 125 grain Polymer/PPT rounds for home defense? Wall penetration concerns? Expert Answer

You could use this Winchester DEER SEASON XP .300 AAC Blackout 150 grain Extreme Point Polymer Tip ammo for self defense. However, it has the potential to still go through a wall, like the majority of 300 Blackout Ammo. The Winchester Silvertip Centerfire .300 Blackout 150 Grain Defense Tip ammo at the link below may be a better option.

I shot a buck using this ammo, took a neck shot and it face planted on the shot. First year using a 300aac coming from a 30-30 lever action. So far I'm extremely happy and will continue to by this ammo!

Great round by Avid hunter, December 24, 2020
I’ve taken several deer with this round. Shoots straight and creates massive damage. My only complaint would be not much of a blood trail, but most of the game has dropped within 50 yards. I’ve never had any issues with cycling in the firearm.
