  • Summary

Today we begin testing the Umarex Synergis for accuracy. There’s been a lot of interest in this budget underlever repeater and today we find out if it’s worth consideration. Up to this point the rifle has tested out very well.

Mount the scope

The 3-9X40 scope comes in a separate package, with the rings separate in another box inside the scope box. The Synergis has a Picatinney rail on top of the spring tube, so it’s quick and easy to attach the rings. They have two-screws per cap so there is no trick to tightening them. Just do it gradually all around.

I always shim the rear ring when I’m testing a new airgun, to offset any drooping problems. As things turned out that was unnecessary for the Synergis, but it doesn’t hurt, either. Mounting the scope took 10-15 minutes.

The test

I shot all my targets for this test off a bench at 10 meters. I used the artillery hold which I will describe as we go. I shot differing number of pellets at each target, so I will also address that as we go.

Usually I have no clue as to what pellet might work in a gun, but you may remember that Umarex included a tin of JSB Exact 8.44-grain domed pellets with the rifle. So I sighted-in with them and also shot the first group. But actually I shot a group that was unintentional during the sight-in.

Sight-in

The first sight-in shot was from 12 feet away and landed in the center of the target at which it was shot. That doesn’t happen often, but I accepted it and went back to 10 meters for shot number two. For shot two I aimed at the target below the first one, but the pellet went into the same hole as the first shot. It’s a little higher and a little more to the left, but it did cut the first hole. By that reckoning the shots have to come down 2-5/8 inches and also go more to the right. I just screwed the elevation adjustment down several turns, because at 10 meters the adjustments don’t move the pellets very far. I also put in some adjustment to the right.

Shot number three hit an inch too high and 3/4-inches too far to the left. So more adjustments and shot number 4 landed inside the black bull. It’s not centered, but I don’t need it to be. So I finished shooting the rest of the 12 shots in the magazine as the scope was now adjusted and was surprised by what I saw through the spotting scope. Seven shots are in a tight 0.246-inch group with the eighth shot opening the group to 0.536-inches at 10 meters. I wasn’t planning on calling this a group but it’s so good that I had to show you. Apparently the Synergis can shoot!

Synergis sight-in
This wasn’t supposed to be a group, but 8 sight-in shots at 10 meters went into 0.536-inches between centers, with 7 in 0.246-inches.

Discussion

Now you need to know some things. First, the scope has fixed parallax that is not adjusted for 10 meters, so I shot this entire test on 4 power and the bull was still a little blurry. I wore my normal vision glasses to shoot. I hope the image will clear up at 25 yards.

Next I will tell you and also remind myself that I shot the sight-in group above with an artillery hold where the heel of my off hand touches the trigger guard. That hold isn’t comfortable because the rifle is extremely muzzle heavy, but as you can see, it does work.

The trigger is absolutely delightful! It still feels very light and breaks suddenly enough that I was able to do good work with it.

The firing cycle is quick and relatively smooth. It does have a quick jolt, but it doesn’t slap your face or anything like that.

Next group

The next group was 12 shots (I had forgotten that the magazine holds 12 and not 10) of the same JSB pellets. I rested the rifle on my off hand out by the cocking slot where the rifle was better balanced and steadier. Twelve pellets went into a group that measures 0.56-inches between centers. I want you to know that I didn’t try to settle down before each shot like I discussed with the Stoeger S4000E last week. I just shot. Because the Synergis is a repeater you can shoot pretty fast. I wasn’t racing the clock, but I was moving right along.

Synergis first JSB group
The Synergis put 12 JSB Exact pellets in 0.56-inches at 10 meters.

After seeing this group I was naturally excited. I wanted to try a couple other pellets, though it seemed like the JSBs Umarex sent me were clearly the best.

RWS Superdome

I tried just 5 RWS Superdomes to see if they were worth further exploration. I continued with the artillery hold by holding my off hand under the cocking slot. This group was very open and measured 1.021-inches between centers. Superdomes are out for the Synergis.

Synergis Superdome group
At 10 meters the Synergis put 5 Superdomes into 1.021-inches. This is not the pellet for this rifle.

Air Arms Falcons

The other pellet I tried was the FFalcon from Air Arms. This is a pellet that’s also made b y JSB, so it should be good, but the test results were a little unclear. Four of the five pellets landed in a 0.525-inch group at 10 meters, but the fifth shot opened it to 0.945-inches.

Synergis Falcon group
Five Falcon pellets made a 0.945-inch group at 10 meters. Four of them are in 0.525-inches.

I think if I had tried I could have gotten Falcons to shoot better than that, but I really wanted to get back to the JSB Exacts that I knew were good.

Last group

This last group was shot with my off hand under the cocking slot. This time, and only this time, I relaxed and closed my eyes before taking the shot. Then I adjusted the hold until the crosshairs stayed on the target after relaxing. This time 10 JSB Exact pellets made a group measuring 0.479-inches between centers. It’s the smallest group of this test, though the first group of 12 shots looks smaller.

Synergis second JSB group
The Synergis put 10 JSB pellets into 0.498-inches at 10 meters.

Second discussion

I think that by both holding my off hand back by the triggerguard and also relaxing between every shot I can get the groups even better. I plan to move back to 25 yards next time because I want to see if the scope that comes with the rifle clears up.

Summary

There you go — the Umarex Synergis is accurate and not that sensitive to hold. The trigger remained light and easy to use and the scope is quite nice, though not clear at 10 meters. The magazine works great but I find myself counting the shots rather than working with the visual cues on the magazine.
