Sig Sauer Elite Copper Hunting Open Tip Match Hollow Point 300 AAC Blackout Ammo 20 Round Box - Nickel Plated Brass Casing

For 300 blackout, the 120gr shoots best out of my 16" 1/8 twist barrel. Very accurate and no malfunctions at all feeding through my magazine and feed ramps. Perfect for home defense as well.

Top end ammo,very good hunting load grouping .700 out at 100 yds

300 black @ supersonic speed is not as fun to shoot but these work good on water bottles

I bought 12 boxes of this ammo at first to try in my 2 Diamondback 300 Blackouts, a 10.5” and a 16”. I shot 80 rounds in my 10.5” gun sighting it in and just breaking it in and the ammo grouped very well, at 115 yards with just a red dot I got 1 1/2” groups. I then ordered 6 more boxes and this past weekend I tried it in my 16” gun and was shocked, at the same 115 yards it was shooting about a 5 to 6 inch group. I then tried this ammo in my cousins 16” Diamondback and got the same results, we both have 1-4x24 scopes on our 16” guns. I then tried some of my cousins Hornady 135gr FTX and shoot 1” groups at the same distance. Shoots fine in my 10.5” and horrible in 2 different 16” guns.

Devastating rounds. Shot a deer out to 80 yards, lung shot, 25 yards blood splatter, deer bled out. Exit wound on the hide is a little over the size of a quarter dollar. Shot a hog at 125 yards, heart shot, hog drop dead after a 15 yard dash. Exit wound is about the size of a golf ball.
