Today we test the Seneca Dragonfly Mark 2 for accuracy with 10 to 15 pumps per shot. It should prove interesting.
My plan today is to pump the rifle 10 to 15 times per shot to shoot 5-shot groups with this pellet. That gives us 6 groups to consider and I will shoot one extra group at the end — so seven groups in all.
I’m shooting off a sandbag rest at 25 yards indoors. The Dragonfly is rested directly on the bag. The rifle is scoped with a UTG Bug Buster 3-12X32 scope that was zeroed in Part 13. I have purposely not centered the shots inside the bullseye to preserve the aim point. And I did not touch the scope adjustments today. I’m using the Air Arms 16-grain dome that my rifle seems to like the best. Okay, let’s begin.
On ten pumps the Dragonfly put five pellets into a 0.237-inch group at 25 yards. It’s nice and round and it looks like just three shots but I swear there were five. It’s the best of today’s test and the second-best of the entire test.
On 11 pumps the group dropped just a bit and five pellets are in 0.429-inches between centers. This is also a roundish group.
On 12 pumps the group seemed to drop a little lower. Five pellets made a group that measures 0.494-inches between centers. And this group is a bit vertical.
Now it’s getting serious. I would never pump the rifle this many times if I wasn’t doing this test. The pumps strokes aren’t getting harder but there sure are a lot of them. I also checked to make sure that all the air was exhausting with the shot by cocking and dry-firing. The gun was empty.
This time the pellets dropped significantly. Five shots are in 0.516-inches between centers at 25 yards.
I’m sweating as I pump now. This really is aerobic! And once again I dry-fired the rifle to be sure that all air was exhausted after the shots. I didn’t do this every time, but a couple times as I shot.
The shots didn’t drop any lower — thank goodness! Five shots grouped in 0.356-inches between centers.
Now it was time for the full 15 pumps. They put five pellets into a 0.297-inch group — the second-smallest of today’s test (with the exception of what is about to come). As before I tested for leftover air and there was none.
The final group
What’s this? Another group? Yep. I wanted to see if the rifle was still accurate on five pump strokes, which gave the smallest group so far. It was just 0.196-inches between centers. And what was it this time, after I had pumped the rifle 375 times?
This time five pumps put five pellets into a 0.277-inch group at 25 yards. I aimed at the letter N in the target title and on shot two I blew it away — so the scope adjustment hasn’t changed.
The best group in this test, going from 4 pumps per shot to 15 pumps, was 5 pumps. Five shots went into 0.196-inches between centers at 25 yards. Second best was 10 pumps and 0.237-inches and third best was 8 pumps and 0.293-inches. That leads me to say that 8 pumps is probably the best for max power, convenience and accuracy and 5 pumps for absolute accuracy. And that is, of course, only for this one pellet.
The rifle performed flawlessly throughout this test. It was pumped a total of 575 times for all the groups. That includes the last 5-shot group for today. The scope remained in place and the zero held.
Remember that I said that this test could engender other tests? Well it has. I think I would like to replicate the best and worst groups — by using the same number of pump strokes. I’ll give you a rest for a little while, but that’s my thinking.
I like this air rifle.
