Most Helpful Positive Review Good ammo bad delivery
Their ammo is ideal for me for home defense purposes. Buying it from Optics Planet was a mistake though as every item in my order was supposed to be available to ship in a few weeks at most bit it took me a year to actually get it.

Accurate and effective.

by Jeff, Verified Owner from AZ, United States Written on May 15, 2025
If you're using a shorty AR pistol for Ranch or neighborhood defense, it don't get much better than this. Extremely accurate and effective against two or four leggers.

Hornady 223 critical defense ammo

by Joe, from PA, United States Written on July 21, 2023
Wow. This was my first purchase from here and I’m kicking myself for not bringing my business here earlier! Ammo purchases are not always so simple but Optics Planet certainly made it easy as ever. They also seem to have much of the popular ammos in stock as much or more than all of the other sites. Also, I appreciate how user friendly the website is.
Best Used for:
  • Self defense

Great defense rounds

by Bill, Verified Owner from VA, United States Written on March 4, 2022
Great ammo for defense, reliable expansion and group extreamly well. The FTX tip makes for a barier blind round that expands and dumps its energy quickly, and if your concerned about over penetraition this is the ammo for you. Makes a match set for my Critical Defense 230 gr 45 acp rounds in my 1911.
Pros:
  • reliable accuracy
Cons:
  • None
Would recommend: Yes

Tiny bullet has tremendous power

by Joe, from TX, United States Written on February 8, 2022
Best bullet for knockdown power have killed several auodad whitetails axis and 2 elk not bad for a 55 grain bullet, you don’t need a .300 win mag to get the job done unless you plan on shooting out to 4-500 yds+
Pros:
  • expansion
Cons:
  • None
Best Used for:
  • An accurate well placed shot
Would recommend: Yes
