I don’t like to use myself or this blog as an authoritative source, but when I research shooting round balls at high speed I find that I have written more on the subject than any other source. Or maybe not more so much as more that has been verified.

Smoothbore Diana 25

To get you started, read this 5-part report on the Diana model 25 smoothbore. Reading that you will discover several things. First, that smoothbore airguns are accurate out to 10 meters when shooting pellets. Next — it takes the right loading technique to shoot a pellet accurately from that airgun at 10 meters. We also learned that the same gun fell apart when the range was increased to 25 yards and shot the same pellets that were accurate at 10 meters. Finally we saw that round balls in this gun were not accurate at all. read more

  • Caliber 4.4mm
  • The fix
  • Power was intermittent
  • Rifled
  • Discussion
  • Summary

Apparently there have been three Dianas model 30. Blue Book of Airguns calls them out and tells us the differences. Last week there was some confusion about which Diana model 30 airgun I was referring to in a comment, and when I clarified it one of our readers asked for a report. It happened that I then visited a friend who has a model 30 gallery gun, and he told me it wasn’t working. I said I would try to get it working again if I could test it for the blog, so here we go.

Description

The Diana model 30 gallery gun is a spring-piston rifle that uses a bolt to cock the mainspring. It’s similar in function to a great many other bolt-action airguns like the Schmeisser model 33, the Anschütz model 275, the Haenel model 310 that copies the Anschütz, and even the Czech models VZ35 and VZ48. All of those airguns are rifles like this one, but if we expand the list to include smoothbores we have to acknowledge the Mars models 85, 100 and 115. There are probably others I haven’t mentioned. read more

  • 10-shots
  • Discussion
  • Summary

You may recall that the Crosman 102 jammed last time I tested it and I had to clear it before continuing. I did that and today we will shoot it at 25 yards. First, let’s clear the jam.

Clearing the jam

Crosman designed the 102 to be easy to clear, but without a manual I had to discover it for myself. The rear peep sight slides to either side, revealing a hole through which many jammed pellets can be removed.

Crosman 102 jam hole
Pull the bolt back and rod the pellet out of the breech. It will fall out this hole.

My jam was more involved, though, and I had to partially disassemble the action to clear it. The top receiver cover is held on by one shoulder bolt that has a large thumbscrew head. Remove it and the top cover slides back and off the receiver. The peep sight is attached to the cover by a rivet and comes off with the cover. read more

  • How to generate power
  • The deal
  • What does this mean?
  • Summary

I am at Sig today, so I won’t be able to comment as much as usual. I have airguns to test, but today I thought I would do something different. Many of our readers have gotten into modifying their guns, so I will address that today. What works, what “works” and what doesn’t.

The mostest-fastest pellet gun!

There are those who want to see just how fast a pellet can be propelled, so they put together a science experiment that uses helium as the propellant gas. They looked on the periodic table and discovered that helium is the gas with the smallest atom that is safe. Hydrogen atoms are smaller, but they remember the Hindenberg disaster. read more

  • Mr. Fix-it
  • Success — sort of
  • Sell your skill
  • Build a better mousetrap
  • What am I saying?

Today I am writing to those readers who think they would like to have a business that deals with airguns. I hear from people all the time who think they would like to be involved in the airgun business. Sometimes they ask for advice. Here it comes, whether or not you asked.

Don’t dabble

The first thing I look for in a person who wants to get into the airgun business (or any business, for that matter) is passion. Do they have passion for what they say they want to do? If a person tells me they are retired and just want to dabble in airguns I tell them that’s like dabbling in skydiving. At some point you have to jump, and then you DEFINITELY have to pull the ripcord! Skydiving gets real serious real fast. read more

This report covers:

  • Remove the stock
  • The stock comes off
  • The trigger housing
  • Now to adjust the trigger
  • Trigger stop screw
  • Trigger pull adjustment
  • Put the action into the stock
  • Installing the safety lever
  • Summary

Today I will discuss adjusting the trigger in the Beeman QB Chief precharged pneumatic air rifle. I promised you a tutorial on the trigger and this is it.

Remove the stock

The first step to adjusting the trigger is to take the barreled action out of the stock. On this rifle that isn’t as straightforward as it sounds. There is just a single Phillips screw holding the action in the stock, and I trust you can all deal with it. But the safety lever on the right side of the triggerguard has to also be removed for the stock to slip off the triggerguard. read more

  • US Army pocketknife
  • Supergrade safety installation tools
  • Crosman Pellgunoil
  • Pelican light
  • Midnight Manager
  • ATF Stop Leak
  • Scragging tool
  • Over to you

Before we begin I want to wish all of the United States a happy Memorial Day. This is the day in which we remember all those who have died for our country. I remember Grady Triplett, who died in Viet Nam far too soon. We were cadets together at San Jose State College in the 1960s. I have visited his name at the Viet Nam memorial several times, and I always think of the sacrifice he made.

Today’s report will be very different. I have wanted to do it for years and just never found the right way, but today I believe that I have. I am going to share with you a few (and I mean a very few) of the tools I use all the time. Then I want you to share with us those special tools you use and why they are so special. Once you read the report, I think you’ll get the idea. read more
