The following data realizes the complete, 74-page report provided by Capstone Precision Group at a Lapua Rimfire test facility comparing 5x .22 barrels at 50m and 100m in a mounted test fixture.  The analysis comprised 2x Structured Barrels and 3x premium, conventional barrels.  All barrels measured 25-inches in length with a 1.25-inch diameter (DIA).  Thus, the Structured Barrels weighed approximately 1.5-2lb (or 23%) less.  Customer and company names are redacted to not detract from the quality of the manufacturer.

Seven events were measured at each distance spanning the listed metrics:
1) DIA of Group
2) Max DIA Group
3) Min DIA Group
4) SD of Ave Group
5) ES Velocity
6) SD of ES Velocity
7) Max Velocity

Aggregating 100m results to clearly distinguish the two barrel types, Structured Barrels took 1st in 7 of 7 events shooting 16 lots of ammo from two manufacturers, and this is in spite of being ~23% lighter than the heavier premium barrels.  They demonstrated measurable gains in ballistic performance, particularly evaluating the SD of the average group and gain in muzzle velocity.
