Competition 22LR Bullet Chrono Tests for SK, Wolf Match Extra, Eley Match

Posted on by

I purchase bricks of ammo and test by Lot #. Using my Garmin chronograph, I test 5 shot groups at 50 yards for speed (MIN MAX AVG) Extreme Spread and of course Standard Deviation.

 

Product          

SK Match Lot 004

Min          Max       Avg         ES        SD

1081       1096.7   1091       16.7      5.4

SK Match Lot 002

Min             Max       Avg         ES        SD

1077.2       1104.2   1089.2       27     10.8

As you can see there is some ES/SD variation of SK Lots.

Wolf Match Extra Lot 135

Min             Max       Avg         ES        SD

1135.9       1156.8   1146.2      20.9     7.3

Eley Match Lot 143

Min             Max       Avg         ES        SD

1125.2       1137.2   1130.1      12        4.2

Serious Competitive Shooters like low SD’s like the SK Lot 004 of 5.4 and Eley at 4.2. Ammo cost goes up dramatically with low SD’s. 

Good Shooting!
