Today we start looking at the accuracy of the Sig Sauer MPX. Lot’s to do so I will get right to it. I shot from a rest and started with the non-optical sights that come with the gun.
Qiang Yuan Training pellets
First up were the Qiang Yuan Training pellets. I have no idea where the sights were set, but since the distance was only 10 meters I figured they would land somewhere inside the pellet trap. In fact they were well-centered and about 1.5 inches below the aim point. Ten pellets went into 1.092-inches at 10 meters. Frankly I was surprised they were that tight. The MPX is more of an area-fire pellet gun and I didn’t expect any real precision from it. This will bode well when I move to an
Air Arms Falcon pellets
Next I loaded 10 Air Arms Falcon domed pellets. Nine went into 1.135-inches, but the tenth shot opened the group to 2.005-inches at 10 meters. Falcons are probably not the pellet for the MPX.
Time to adjust the sights
After these two groups landed low it was time to adjust the sights to raise the point of impact. On the MPX you adjust the front sight for the elevation. And when you move a front sight you do so in the direction opposite where you want to round to go. So I grabbed the special tool and adjusted the front post down as low as it would go. That was a total of three clicks, which wasn’t enough.
Sig Sauer Match Ballistic Alloy pellets
Now it was time to try the Sig Sauer Match Ballistic Alloy pellets that were sent with the gun. These are priced as premium pellets, so I expected them to perform and I wasn’t disappointed. Ten grouped in 0.97-inches at 10 meters — the smallest group of the test! To say I was impressed is an understatement. They were higher but still too low.
H&N Finale Match Pistol pellets
The next pellet I tried was the H&N Finale Match Pistol pellet. Nine of them went into a very tight 0.904-inches, but one pellet opened that to 1.531-inches. This would be a pellet to experiment with further.
Install the dot sight
I then installed the dot sight that came with the rifle, because I hope to shoot the Sig Texas Star and the Air Venturi Wonder Wheel action targets next. That won’t work unless the gun hits what I aim at.
I set up a 10-meter pistol target, thinking there would be a lot of sight adjustments to make, but when my first shot scored a 9, I just finished the group. These were with Qiang Yuan pellets that I mistakenly thought were the most accurate. Ten shots went into 1.295-inches at 10 meters. That’s not as good as I did with the peep sights, but it’s close. It will work for an action target.
Evaluation so far
So far the MPX is doing well. I’m sorry the onboard sights won’t adjust far enough, but the dot sight compensates for that. The trigger is light enough for good work and the semiautomatic action works as advertised. Best of all, that belt of pellet chambers doesn’t appear to have degraded the accuracy.
Next time I will try the gun on the action targets, and we’ll see how that goes.
