I have used the 300 blk out for the last 2 seasons in both my bolt guns and 1 AR. I've taken several does, pigs, coyotes, and various smaller critters. Used within 200 yards or less, it's a great Texas hunting round. I have used bullets from 110 V-max, 115 Berger, and my favorites being the 125 grain variety.
The 110 V-max is a good round, but for tough pigs with a varmint bullet, it will fragment a little easier and limit penetration. The 110 V-max works great for deer, though.
The 115 Berger is a target bullet with a very thick jacket, and will hold together very well for deep penetration. I've taken several coyotes and 2 does with this bullet, and all were DRT with a good size exit wound. For it being a target bullet, I like using it for hunting also. (Plus they are on sale for $88 per 100, and I have about 25,000 of them!)
The 125 grain bullets are my preferred bullets. I have used the 125 Ballistic Tip, Hornady SST, and Sierra SP. These weight bullets offer the best expansion with deep penetration. On some of the larger pigs, customers have sent me pictures of perfect mushroom shaped bullets recovered from the opposite side shoulder under the skin. I generally used these bullets for hunting.
The 110 Barnes is a good solid copper bullet. It has a large hollow point behind the big plastic tip for expansion. You will get deep penetration with this bullet, but IMO, it lacks the hydrostatic shock, which the lead bullets provide. But it will still work well.
I have also taken a large pig with a 150 grain Ballistic Tip. I shot this pig running at about 50 yards, and the bullet entered right behind the shoulder. The pig piled up in about 40-50 yards. The exit wound was smaller than a dime size exit. This tells me this bullet did not expand much, if any at all. The 150 or heavier will work, but these bullets are going too slow for reliable expansion.
If you keep the bullet weight 125 grains or less, the blk out is a VERY effective round for Texas game. I will be using it again this season. I like the smaller, light weight rifles with the light recoil. And adding a suppressor to the rifle makes things really quiet!
