As a Military Rifle Instructor assisting the USAMU deliver SDM Training I’ve witnessed a lot of rack grade M16A4’s shot by students in bipod supported prone position where their Mk262 rounds held an MOA at 600 meters when wind was correctly appraised and eyeballs were consistently placed behind eye box of ACOG. No doubt this is testimony for the rifle, ammunition, and student marksmanship. For best results at any distance/ target the Blackhills Mk262 round is boss. Now, in US Service Rifle Competition this round is ideal for 200 and 300 yard stages for the non-handloarder. At 600 yards the 80 grain Berger is a better performer having an MOA wind constant of 10 vs the 8.5 from the 77 grain bullet. One more thing, add a free float rail to M4 or M16A4 for assured sub MOA even from hard hold.

Honestly I believe the ammunition is extremely overrated when it comes to terminal ballistics. Usually anywhere from 4"-6" penetration before expansion and penetration depth seems rather inconsistent. It's still an amazing round that carries beautiful accuracy. It's definitely a top 5 or arguably top 3 contender. I personally believe a heavy, bonded softpoint from 62 - 75g gives a much better overall result across practically all barrel lengths and twists. I've been able to get sub moa with Speers 62g & 75g with ease and the results I've personally seen on coyotes, large feral hogs & whitetail deer here on the ranch have been phenomenal when directly compared to sierras 77g offering.
