Precision tolerances and a lugless receiver make switching barrels about a five-minute job on the
AI-AW.
The drop values on the authors "dope card" are almost identical to .300 Winchester Magnum's standard
190-grain load.
A .308-caliber sound suppressor works effectively to reduce recoil and report on the smaller 6.5mm
caliber; here it cools with the mirage cover retracted during a break in load development.
