Sig Sauer Super Target Part 6
Fully leaded: shooting Sig’s new Match Pb target pellets
By Dennis Adler
As promised, there is one last test to be done with the ASP Super Target using the new SIG AIR Match Pb series 7.71 gr. lead wadcutters. The weight difference between a 7.0 gr. wadcutter compared to the new SIG AIR Pb wadcutter’s 7.71 gr. is obviously going to result in a lower average velocity and I will run a 1:1 comparison switching from Meisterkugeln 7.0 gr. to the new Pb 7.71 gr. and chart the velocity variations for 10 shots.
The greater question with the heavier SIG AIR Pb is going to be accuracy at 10 meters vs. the lighter weight 7.0 gr. wadcutters, and more so, compared to the lightweight 5.25 gr. alloy wadcutters, which gave me a 0.5 inch group at 10 meters from a benchrest. To simplify the initial comparison between the Meisterkugeln and SIG AIR wadcutters, I am not going to readjust the sights on the Super Target from the alloy wadcutters I used last, but rather put up a target with a grid that can allow me to better chart the different POI shooting at the same center dot. I made these up myself awhile back so I could make more exact adjustments when sighting in lasers, but they will serve this purpose, too. Since the Pb wadcutters from SIG AIR are match grade, I am going to go on the assumption (always a big risk) that they have more consistent uniformity.
My 10 shots with Meisterkugeln clocked:
The average velocity with the 7.0 gr. Meisterkugeln was 347 fps with a standard deviation of 4 fps. Switching to the new SIG AIR 7.71 gr. Match Pb, 10 shots clocked:
The average velocity with the SIG AIR Match Pb was 311 fps with a standard deviation of 4 fps, same as the Meisterkugeln, but the loss in average velocity with the heavier pellets is a noteworthy 36 fps, with the high velocity spread between the Sig and Meisterkugeln being 353 fps vs. 319 fps. Even though standard deviation is 4 fps for both, the consistency with the Meisterkugeln was better shot for shot.
The lower velocity with the 7.71 gr. wadcutters is to be expected, but the question is, will a more random velocity spread of 12 fps over 10 shots with the Match Pb, have an impact on the Super Target’s accuracy at 10 meters? The spread with Meisterkugeln was 10 fps, from lowest to highest velocity.
10 meters with Match Pb
I shot 10 rounds at the sighting target with the sights held on the red dot and not adjusted for the heavier pellets. The 10 shots were not as consistent as I had expected and gave me a spread of 1.75 inches, with the closest five rounds measuring 1.24 inches. I switched to a 10-meter target and shot five rounds with the SIG AIR pellets off the bench and adjusted POA. My 5-shot group measured 1.24 inches, and needless to say I was disappointed in my shooting with the Super Target and Pb Match pellets. So, one more try. I can’t say that I am thrilled with this target either, since all my shots hit high and left even with POA corrections. I have to come to a temporary conclusion that the Super Target and the Pb Match are not the match I was hoping for. Still, this last 5-shot group did pack all five into 0.875 inches. I shot one final target with the Super Target using Meisterkugeln and put five shots into 0.875 inches once again.
There is an inconsistency in accuracy between lead and alloy pellets and I can’t rule myself out, but I know that for my match with the Super Target, alloy pellets got the job done. Back to you.
