Today I’ll shoot the Diana 240 Classic at 25 yards. This is a delightful little air rifle that’s perfect for those who want something lightweight, easy to cock and accurate.

The test

I’m shooting the rifle rested directly on a sandbag at 25 yards, using the open sights that came on it. You might want to read Part 3 again, as I shot 10 shots into a smaller group than 5 shots. That’s a one-in-a-thousand occurrance, but it did happen. And that was how I selected the first pellet to try at 25 yards.

JSB Exact RS

First to be tested was the JSB Exact RS pellet. I got a stunning 0.428-inch ten-shot group at 10 meters last time, so I thought things would continue at 25 yards. Alas, they didn’t. Ten RS pellets went into a very open 1.311-inch group. I was surprised, because I had expected a 0.90-inch group from this pellet.

Trigger

I must comment on the trigger of this rifle. It’s light and crisp. It may not be a Rekord, but it sure is nice!

Tune in a Tube

You may recall in Part 3 I squirted some Tune in a Tube into the mainspring. That calmed a slight buzz and now the 240 feels wonderful. I can’t say enough good things about that product.

Air Arms Falcon pellets

Next I tried some Air Arms Falcon pellets. Falcons are often the best in lower-powered air rifles. This time, though, the results were both stunning and confusing. Ten pellets went into 1.85-inches at 25 yards. That’s hardly encouraging. However, 6 of those pellets are in a tight group that measures 0.383-inches! What’s happening?

This is why I shoot 10-shot groups, rather than 5-shot groups. I have no idea what’s going on with this group, but it sure makes me want to scope this little rifle and try again!

RWS Superdomes

For the final pellet I tried some RWS Superdomes. Ten went into an open group measuring 1.612-inches between centers. I would normally say it isn’t the pellet for the 240, but I think I’ll wait to see how it does when it’s scoped.

Evaluation

The Diana 240 Classic is a fun little air rifle to shoot. And, if you were plinking at cans at 25 yards, you probably would have connected with every shot. I don’t think these results are terrible — they just look bad because they are on paper.

I certainly want to scope this rifle and try again at 25 yards. That 6-shot group of Falcons has me intrigued.
