Ammo Testing Results
Last night I performed the second round of ammo testing for my rifle. This article serves as a sequel to ‘My First Rifle ’ which explains the purchase of my first rimfire rifle and the initial ammo testing I performed with it.
This second round of testing was done in the same way as the first, except that I tested the ammo in reverse order (to make sure the lubricated SK Mag. I used first last time wasn’t having any impact on subsequent rounds). I was also better prepared this time for the drop in height of the CCI Quiet rounds, so was able to test them properly.
The results of the second round of testing are as follows:
Ammo | 1st Group | 2nd Group | Average Group Size |
---|---|---|---|
SK Magazine | 23mm | 16mm | 20mm |
SK Standard Plus | 20mm | 17mm | 19mm |
CCI Standard | 25mm | 17mm | 21mm |
CCI Quiet | 71mm | 89mm | 80mm |
Federal Premium Gold Medal | 34mm | 27mm | 31mm |
Federal Premium Standard | 19mm | 16mm | 18mm |
Eley Club | 20mm | 20mm | 20mm |
Eley Edge | 22mm | 18mm | 20mm |
These results, when compared with the initial round of testing, are interesting:
- The better ammo from the first test (SK Mag., SK Std. Plus & Eley Edge) all performed worse the second time around
- Federal Premium Std. performed exactly the same
- The rest of the ammo performed better
- CCI Quiet is pathetic (at 50m)
When I calculated the average of the first and second round of testing for each type of ammo, I came up with the following final results:
Ammo | Average Group Size | Placing |
---|---|---|
SK Magazine | 16mm | 1st |
SK Standard Plus | 18mm | 2nd (tied) |
CCI Standard | 22mm | |
CCI Quiet | 80mm | |
Federal Premium Gold Medal | 33mm | |
Federal Premium Standard | 18mm | 2nd (tied) |
Eley Club | 21mm | |
Eley Edge | 19mm | 3rd |
So it looks like I’ll be sticking with the SK Magazine ammo!
