Three targets, widely spaced, at any range from 25 yards/meters to 500 yards/meters. Use standing position at close range(s), kneeling, prone, or (vehicle) supported position for long range(s).
30 rounds, firing controlled pairs (aka double taps), in timed fire, using same time limit for each. Determine number of hits for each weapon.
Ammunition
5.56 NATO 62gr M855
6.5 Grendel 110gr Wolf FMJ or 120gr Wolf MPT (or handloads w/Norma 120gr FMJ)
Stan:
Since you are talking service grade rifles / carbines -- best state that the Grendel must be service grade too. Most likely can be done by identifying the Grendels on the market that you would consider service grade. This eliminates the Shilen, Krieger, and Satern match barrels.
Weight and length limitations are also part of the requirements and should be stated.
Also, no compensators.
Not sure what your research question is or your hypotheses.
