Federal 62 Grain Fusion vs Federal 62 Grain Fusion MSR vs Speer LE 62 Grain Gold Dot

 By: MOLON

The muzzle velocities shown in the tables below were obtained back-to-back during the same chronograph session using recent lots of all three of the Fusion/Gold Dot loads chrongographed.

Atmospheric Conditions

• Temperature:  73 degrees F (plus or minus one degree)
• Barometric Pressure:  29.68 inches of Hg
• Humidity:  62%
• Altitude:  950 feet above sea level 

Muzzle velocities from a 20” Colt M16A2 barrel with a NATO chamber, chrome lining and a 1:7” twist.

Muzzle velocities from a 14.5 Noveske N4 light barrel with a NATO chamber, chrome lining and a 1:7’ twist.

10-shot groups fired from one of my precision AR-15s with a Lothar-Walther barrel with a 223 Wylde chamber and a 1:8” twist.  The groups were fired from the bench at a distance of 100 yards with the same windage/elevation settings on the scope for each of the three groups.
