  • Summary

Today we look at the accuracy of the scoped .177-caliber Seneca Dragonfly Mark 2. It’s been a minute since we last looked at this rifle, so let me remind you of something. I did an extra accuracy test with the open sights and all it showed was which pellets were accurate and which were not. I’m shooting several of those same pellets today so we have a basis for comparison.


I mounted a UTG Bug Buster 3-12X32 in the rifle. That’s the same scope I used on the .22-caliber Dragonfly Mark 2 for many accuracy tests. It took me 90 minutes to mount the scope because I had forgotten so many details about the rifle. It actually should have taken about 15 minutes. Then sight in took a little more time. But finally I was ready to test the rifle.

The test

I shot the Dragonfly Mark 2 from a sandbag rest at 10 meters. I shot 5-shot groups because this is a multi-pump and I wanted to finish the test today. Let’s get started and see what she does.

Baracuda Match with 4.50mm heads

First up were H&N Baracuda Match pellets with 4.50mm heads. I sighted in with them as well, so I felt they were the right pellet to start with.

Five Baracuda Match domes went into 0.427-inches at 10 meters. The group is well centered and just below the center of the bull to preserve my aim point.

In the last test with open sights the same pellet made two groups measuring 0.912-inches and 0.508-inches between centers. Today’s group isn’t enough smaller to say much about the accuracy of the rifle  scoped versus unscoped.

JSB Exact 8.44-grain

Next to be tested were five JSB 8.44-grain domes. The Dragonfly put them into a 0.421-inch group at 10 meters. In Part 5 with open sights the Dragonfly put the same pellet into 0.71-inches. So the scoped rifle is a bit more accurate when shooting this pellet.

Five JSB Exact 8.44-grain pellets made a 0.421-inch group at 10 meters. 

This group is very vertical, and the group made in Part 5 is vertical as well. It’s reassuring to see things repeating like that.

JSB Exact Heavy

The JSB Exact Heavy is a 10.34-grain dome. In today’s test five of them went into 0.223-inches at 10 meters. In the test with open sights the same pellet grouped five in 0.48 inches. This is a pellet to consider.

The scoped Dragonfly put five JSB Exact Heavy pellets into a 0.223-inch group at 10 meters.

I will say this. Shooting one small group proves nothing beyond I did it. But I am looking for pellets to try at 25 yards in upcoming accuracy tests and I want to select the ones most likely to be accurate.

Sniper Magnum

The last pellet I tested today was the H&N Sniper Magnum. It grouped five into 0.503-inches between centers with four in 0.223-inches. In Part five with open sights I put five into 0.322-inches at 10 meters. This is a second pellet to shoot at 25 yards.

The Dragonfly Mark 2 put five Sniper Magnums into 0.503 inches at 10 meters.

The one hole that’s not with the rest was shot number 4. There was no called pull; the pellet just went there.

Still easy pumping

The Dragonfly is still very easy to pump. That makes it quite convenient for a scope because you don’t have to hold it where the scope sits. You can hold it by the pistol grip and it still feels fine.

Compared to the .22?

This .177 has not yet equaled the accuracy of the .22-caliber Dragonfly, but I’m not giving up. The next test will be at 25 yards, now that the rifle is scoped. 


The Seneca Dragonfly Mark 2 is a revolutionary new multi-pump pneumatic that is revolutionizing the world of pumpers. It’s a landmark to what persistence can do when a good idea is on the table.
