Today’s report is a guest blog from reader Bob who has been a daily reader since 2011. He read my remarks about the accuracy of a Beeman R7 in a recent report and decided to see if they were correct. If you’d like to write a guest post for this blog, please email me. Take it away, Bob.

I am an enthusiastic shooter, and have been an enthusiastic reader of B.B.’s blog since 2011. Like many of us, I read (in no certain order) the morning news, email, and B.B.’s blog before my first cup of coffee. I’ve learned a lot from B.B. and readers’ comments.

Big day!

Today is the big day! Today I test Geo791’s .22-caliber Diana RWS 34P air rifle to discover how accurate it is. I have been thinking about this test for a long time and have come to the conclusion that there is just one thing I want to know — how accurate is this rifle and is it consistent? That sounds like two things, but it’s really two parts of the same thing. Is this air rifle accurate enough to kill pests?

We have had many conversations on this blog about the level of accuracy needed for that purpose, but I said I wanted to see the rifle put 10 shots into a group that’s under an inch at 25 yards, when open sights are used. I don’t need to see that accuracy with many different pellets, either. If I were to go that route, this test could turn out to be a lifetime affair! I’ll let Geo791 do that, as the owner should.

Checking out a Diana RWS 34P: Part 2

The Diana RWS 34P is a classic breakbarrel spring-piston air rifle.

  • Trigger pull

  • Evaluation

Today we are back with reader Geo791’s Diana 34P, and we’re looking at the velocity. This is a .22, and a fresh one should produce velocities and power in the same neighborhood as the Beeman R1, but not quite as powerful. George was never concerned about the power of his rifle — only the accuracy that he thought was sporadic. But I do plan to tune his rifle with a Vortek kit that was donated by Vortek for this series, so either way, he wins.

Power has little affect on accuracy. Sometimes if a shot cycle can be smoothed a lot you may see tighter groups, and other times if a weak powerplant is restored to new or better the airgun might shoot better. But typically I tell people that accuracy lies in the barrel and not in the tune. However, just because I say it doesn’t make it so. We shall see.

How to make a spring-piston air rifle shoot smooth: Part 1

This report covers:

  • Strange report
  • The beginning
  • Over and out
  • Throttle brought it back
  • Lower velocity
  • Summary

Strange report

Today’s report is a bit strange. It could be considered one about an historic airgun, because the gun I will talk about is no longer made. I decided instead to put it into the modern section, for reasons I hope will become apparent.

It also could be considered as an open letter to airgun manufacturers, because it deals with an air rifle many shooters potentially want, though most of them don’t know it until they actually shoot the gun.

Finally, it could be considered as a chastisement of some airgunners who think that more power is the only path to happiness with an airgun. Why don’t I just tell the story and let you readers decide?

Diana 240 Classic: Part 5

This report covers:

  • JSB Exact RS
  • Air Arms Falcons
  • RWS Superpoints
  • Summary

Today we examine the accuracy of the Diana 240 Classic at 25 yards when scoped. I think this will be interesting.

The scope

I mounted a nondescript Gamo 3-9X40 scope for two reasons. First, it was already in rings that would fit the rifle and second, it is the type of scope many shooters would mount on a rifle like the 240. This is the kind of scope that comes bundled in a combo, so I can’t give you a link, but we are talking about a $40 scope at the most. There is no parallax adjustment, so at 9 power the target was a little fuzzy, though I used a target with a one-inch red center that made centering the crosshairs easy.

How do you know…?

This report covers:

  • August’s question
  • Experience
  • How do you tell…
  • Expected power
  • Piston stroke
  • Age of the gun
  • Chronograph or other means of power determination
  • How do you know? — case 1
  • Case 2
  • Last point
  • The last word

Today’s topic tries to address a question I am sure many newer airgunners have at some point. How do you know when a spring gun need repair? It was asked last week by reader August, who lives in Germany. Here is what he asked.

August’s question

”How do I recognize that an older gun piston seal is going bad? From reading the blog I gather that I can chrony it. But this gun delivered until right before the final breakdown. Only the last five shots it became slower. On opening the gun I saw that the outer part of the plastic seal was detached from the rest and had blocked the spring tube probably causing the older spring to break.

Checking out a Diana RWS 34P: Part 1

Diana 34P
The Diana RWS 34P is a classic breakbarrel spring-piston air rifle.

This report covers:

  • George’s rifle
  • Are Diana 34s ever not accurate?
  • Examining George’s rifle
  • It it a scope problem?
  • Use open sights
  • Condition of the test rifle
  • What I plan doing
  • What if it’s not accurate?
  • What does accurate mean?

Today we start looking at the Diana RWS 34P rifle that reader Geo791 has had trouble with. If I understand his problem, the rifle will not group for him. I think he said the best he could do at 25 yards was 10-shots in a group measuring 1.5 inches between centers of the two widest shots. George, if that’s not accurate, please enlighten us, because we want to know exactly what we are testing here.

George’s rifle

George’s rifle is a .22. He bought it for pest elimination. As I recall, the garden was the primary area of concern and chipmunks were the principal target in the beginning, but squirrels are now on the list too. He bought a .22 because he read that is was better for taking game, which I would absolutely agree with. Not that a Diana 34P in .177 can’t do the job, but in .22 it’s a lot more positive. That’s assuming you can hit what you shoot at, which brings us to the problem I am evaluating.
