    The 69 gr SMK is THE best load for my built DMR.

    Stunned by the 1st five shot group with the Gorilla .69 grain Sierra Matchking ammo. Had not shot my 16″ barreled custom build in over a year. Only running a fixed 5 power Primary Arms Prism Aurora Reticle (chevron) at 100 yards. My eyes suck and I am old. Was not wearing my glasses and shot less than MOA easily at 100 yards. First four shots made a bit of a ragged hole about .5″ with my 5th shot elongating the group a bit. Wish I could upload a picture. I am not an experienced range person and believe with a better cross haired scope for my old eyes could be very consistent with this ammo out of this 16″ shooter.

    I have been shooting the 69gr Sierra Match King Gorilla for almost a decade now in my AR-15s. My 18″-barrel AR-15 can shoot a .6MOA 5-shot group with this ammo (100YRDS), and my 13.9″-barrel AR-15 can shoot a .8MOA 3 shot group with this ammo (100YRDS). I have a YouTube channel called Big Timber Lodge where you can see me shooting these groups live at the range. I am not plugging myself, but if you don’t believe me about how accurate this ammo is, you can go watch it yourself in action.

    My AR liked a different brand that also used the 69gr bullet but I couldn’t find any in stock. Found the gorilla 69 grain in stock and thought I’d try them. Shoot sub MOA in my AR easily. I was hitting a gong out to 550 yards in no time. Great ammunition

    I will be the first to admit that I’ve never heard of this company or it’s ammunition. I ordered some .223 to “lessen” the bourbon and practice more compared to the expense to shoot my 6.5 creedmoor PRS rifle. First range session was sight in. I was totally amazed at the 100 yard groups that I was getting, well less that 1/2″ moa at 100 yards. After determining ballistic coefficient and velocities for the kestrel, next step was 500 and 600 yards. This ammunition shoots lights out even at those distances. I have a KYL target with 6 steel targets ranging from 8″ down to 1″. At 300 yards, I have no issues consistently hitting the 1″ target with the .223. My only complaint is the primers. Had a few FTF(fail to fire) and after contacting Gorilla, it was determined that the issue was with harder than normal AR primers. Quick firing pin spring upgrade resolved all FTF. I am a customer for life.
