SK Biathlon ammo
Posted: Tue May 29, 2018 8:05 pm
At this Saturday's smallbore match, I had a few rounds of the SK Magazine ammo hitting the rail and not the body of the animal. I have also been hearing that other shooters have been having the same problems.
I shot 30 rounds of the SK magazine ammo through the chronograph. I did not shoot for any type of group size.
There were 2 low shots out of the 30 rounds. They were 975 and 989.
The other rounds were between 1010 and 1081. The lo: 975, high: 1081, avg: 1035, ES: 106 and SD: 22
By removing the 975 and 989 from the group, it was a little closer. Lo: 1010, High: 1081, Avg: 1039, ES:71, SD: 18
With 28 rounds having a spread of 71 FPS, that is not very consistent ammo. It is hard to win a match with the ammo not grouping as tight as it should. With the SK Magazine ammo not performing like it should and having some under powder rounds, has any body tried the SK Biathlon ammo?
I ordered 2 bricks of it today from Cathy at Good Shooting.
When it comes in, I plan on firing 30 rounds through the chronograph and for group size at the same time. I will also do this with the SK Magazine ammo for a comparision. Thanks Ken
