Precision Guns and Optics: A Winning Combo

PostMammoth

Daniel and I shot the Mammoth Sniper Challenge as a team, competing in the Extreme Tough Man division. The match, known for being one of the most difficult, required that we carry all the guns, gear, ammo, and food we needed for three days/two nights and eight courses of fire. We rucked everything, through obstacles, for a total of 23 timed miles (18 minutes per mile maximum).  We slept outside in freezing temperatures and shot dynamic stages that tried our physical limits just as much as our marksmanship skills. Our success was undoubtedly determined by our keen selection of guns and optics.

We ultimately won the match because we made our hits. I shot primary; my targets were 400-1040 yards. Daniel shot secondary; his targets were 150-650 yards. The target sizes ranged from ½ to 3 MOA.

Our rifles were identical (total weight of each rifle with scope and bipod was 14.5lbs).  Here’s the breakdown:

  1. Congratulations on the absolutely great shooting. Your rifles are fantastic and I will be reaching out to PROOF Research about the barrels for some upcoming rifle builds I am planning.

    • Thanks so much! Those PROOF Research barrels were so impressive! Each 28″ barrel was about 6lbs. lighter due to being carbon fiber wrapped. We were shocked at the accuracy of both rifles straight out of the box! Your money will be well-spent. Please let me know how it works out for you!

    • Hi! Thanks for the question. I am going to be doing another complete review of the gear we used. But, in short, we used Gregory Baltoro packs (Daniel’s was a 75, mine was a 65). I’ll have that article up with in the next week.
