I have been precision shooting for over 15 years as a military sniper, hunter, and firearms instructor, and I've rarely seen factory match ammunition perform as well as Sphere R&D's 77-grain OTM 5.56. This is some of the best out-of-the-box ammunition available, and its standard deviation of less than 14 FPS truly speaks to its quality.

I began by shooting groups on paper at 100, 200, and 300 yards with my IWI Zion SPR. All groups were consistently around 0.8 MOA, which is about the capability of the rifle. The following week, I extended the distance from 400, 600, and 1000 yards, achieving consistent hits throughout.

Sphere R&D's 77-grain OTM is outstanding, and I highly recommend it to any serious long-range shooter.
