.223 Remington, 55gr Sierra BlitzKing© – 20 Round Box

Gorilla Ammunition utilizes only the highest quality components to manufacture top quality match grade loads and this offering chambered in 223 Remington with the Sierra BlitzKing© is no exception. Factory new cases, match grade primers and top quality projectiles make this load a go-to choice for competition or small game hunting. Component selection is only the start to our top quality ammunition. The Gorilla Ammunition manufacturing process ensures consistency by pairing high end linear loading equipment with multi stage in-process inspections by highly trained machine operators with a final inspection of each and every round by our quality inspectors to ensure only ammunition that meets our rigorous specifications makes it into the box. The SierraBlitz© King selected for this load is designed for explosive expansion in varmints and small game with the accuracy characteristics of the MatckKing© bullets. The nose of the Sierra BlitzKing© are made of a proprietary acetyl resin compound, and the sharp tip improves the ballistic coefficient over the traditional flat-base Spitzer bullet design. The 55gr variant used in this load features a boat tail to further increase the ballistic coefficient compared to flat-base design bullets of the same weight.

    Excellent ammo at a nice price. Fast shipping.

  2. Chance Hogwood (verified owner)

    Bought this ammo for hunting coyotes. It works and shoots great. Wish I could get more of it.

  3. Michael Stafford (verified owner)

    This is great ammo, at least in my Centurion Arms CM4 where I have gotten 1/2 inch groups. My AR likes Winchester and Federal ammo, now Gorilla goes to the head of the class.

    I’ve shoot a lot of different 223 ammo. I’ve gotten to the decision to replace all my ammo with this gorilla ammo. It really does shoot under 1/2 moa in my s&w m&p 15. Is a little pricey but when you hit exactly where you are aiming it’s worth it. I think most people don’t know how accurate their AR can be. My AR was not expensive but with the right ammo it shoots very good. Worth trying a box to find out. I definitely recommend.

    Shot this today on a 1/8 twist DPMS 20 inch barrel I was about to give up on! Until you find that one load that will shoot lights out.
    I got around 1/2 moa at 100 yards , and stayed just over a 1inch at 200 yards. Actually shot better than Hornady 55 vmax. Shipping was very fast. Especially for the uncertain times we are in. I’m definitely getting more of this when available.

  7. Gordon C (verified owner)

    I am not a experienced shooter, got a new S&W AR 15. But read positive responses on this ammo. It is very consistent, no problems, very accurate sighting in at 50 yards. Little pricey for range practice, but top quality ammo. Customer service is great also. Will buy more.

  8. Mark Thomas (verified owner)

    Awesome ammo! Consistently shoots under 1/2 moa @100yds with my RRA Eichler. The only ammo I will shoot! Fast prompt service from Gorilla! Highly recomend!!

  9. Keith (verified owner)

    Bought this ammo on a whim after seeing it reviewed online by multiple people, I’m glad I did! Shooting tight, consistent groups at 50 yards made me never want to buy cheap ammo again. Customer service is also top notch and speedy. A winning combination.

  10. Treyh007

    Best all round 223 ammo I’ve shot, this stuff is accurate in all 4 of my 223/556 rifles/pistols. Been using it for a few years now, it’s my go-to 223 ammo. I highly recommend!
