Air Venturi Dust Devils will hit the market in a few months.

Part 1

This report covers:

  • How to test?
  • Test 1. A single-stack forced feed BB gun
  • Daisy BBs in the Daisy 25
  • Dust Devils in the Daisy 25
  • Power in the Daisy 25
  • Test 2. Gravity feed with a magnetic breech
  • Daisy BBs in the Red Ryder
  • Dust Devils in the Red Ryder
  • Power in the Red Ryder
  • Test 3. A CO2 gun with cartridges
  • Daisy BBs in the SAA/li>
  • Dust Devils in the SAA
  • Power in the SAA
  • Velocity comparison
  • Feeding
  • What’s next?

Today I begin testing the new Air Venturi Dust Devil BBs that you read about in Part 1. To say the interest is high is an understatement.

How to test?

How do you test something that’s so new that there isn’t much precedent? I decided on the following. In Part 1 we learned that the Dust Devils weigh about 4.35 grains, so they will go faster than conventional steel BBs that weigh about 5.1 grains. I thought that was the place to start, but with a twist.
Instead of just doing a velocity test, I thought I would select three different kinds of BB feed systems and also see how well Dust Devils feed in each of them. There are more than three types of BB feeding systems, so we won’t cover everything today, however, once we see how the Dust Devils compare to standard steel BBs we may not have to test their velocity any further in the future. We will see as this test unfolds. read more


The development of the .22 rimfire cartridge: Part 1

A history of airguns

This report covers:

  • Two centuries?
  • Reverend Alexander Forsyth
  • Maintainence
  • Danger
  • Percussion cap
  • Flobert
  • Gallery guns
  • Galleries again
  • Recap

Today we begin a subject that lies at the heart of the airgun. Rather than try to defend that statement at this time, I will present evidence as we go, because the body of evidence is both large and spans much of the over two centuries of the rimfire cartridge history.

Two centuries?

Wait a minute, BB. I just read on Wiki that the .22 Short — the first .22 rimfire cartridge — was patented by Smith and Wesson in 1854 and launched to the public in their new revolver in 1857. Today is 2018. That’s only 161 years. How can you say the rimfire cartridge has been in development for over 2 centuries? read more


Something else

This report covers:

  • Always something else
  • Change it
  • Make ‘em pumpers
  • Farco air shotgun
  • A good rifle
  • The 1873 Springfield
  • A long shot
  • The point
  • Summary

Always something else

One thing has stood out about airgunners for me. No matter what you are talking about, they always seem to want something else — something different. I remember many years ago when powerful precharged guns didn’t exist, the Yewah 3B Dynamite multi pump from Korea was looked at as a big deal. It was powerful, large caliber (.25) and airgunners were in awe of it — mainly because few of them had ever seen one.

Change it

Then I read about a guy who had one and reported how very powerful it was, but, man, was it ever hard to pump! The 3B required 150 pump strokes to fill initially, and then you could top it off after every shot with another 20 pumps. This fellow liked the power but hated all the work. So he machined a fill coupling and turned his 3B into a precharged airgun! He said the gun became lighter when the pump mechanism was removed, and it was no longer a chore to fill. read more


Sig Sauer Spartan BB pistol: Part 3

Sig Spartan BB pistol
Sig Sauer Spartan BB pistol offers a lot of pistol at a budget price.

Part 1
Part 2 

This report covers:

  • The test
  • H&N Smart Shot
  • Hornady Black Diamond BBs
  • The trigger
  • Air Venturi Zinc-Plated BBs
  • Overall evaluation

It’s accuracy day for the the Sig Spartan BB pistol, and I have to tell you I am excited. The trigger on this pistol, while heavy, breaks so crisply that I am expecting good things.

The test

I shot from 5 meters, seated and resting my shooting arm on a UTG Monopod. The Spartan’s sights are fixed but they are wide enough for good accuracy and the front post is sharp. There was no problem seeing the sights on the target for a 6 o’clock hold.

H&N Smart Shot

I tried the H&N Smart Shot lead BBs first. I did that because the Spartan only got 40 good shots on a CO2 cartridge in Part 2 and I wanted the pistol to be as powerful as possible with this heavier BB. read more


Nothing new under the sun

This report covers:

  • You made me do it
  • Air shotguns
  • You don’t understand!
  • BUT — it’s been done
  • All-metal 760
  • Summary

You made me do it

I should give credit for today’s short blog to you readers, because if it weren’t for your investigations into a more efficient insect killer this past weekend, I never would have written this report.

Air shotguns

You talked about an air-powered shotgun all weekend. Veteran readers are aware I have written about air shotguns many times in the past.

Sig P320 pellet and BB pistol: Part 3

Part 1
Part 2

This report covers:

  • The test
  • Air Venturi Steel BBs
  • Hornady Black Diamond BBs
  • Analysis
  • Trigger
  • Belt reliability
  • Air Venturi Smart Shot BBs
  • Evaluation

Today I look at the accuracy of the Sig Sauer P320 pellet pistol with BBs. These combination guns can sometimes be great with both BBs and pellets, but usually they are good with one and not as good with the other. The difference is due to the size difference of the projectiles. We will look at the accuracy with pellets in Part 4, so today it’s just BBs.

The test

I shot from 5 meters (just over 16 feet) with the pistol resting on the UTG Monopod. I was seated, so only the pistol was being tested — not me. This pistol has good crisp sights for target work, though they are not adjustable. read more


Ballistic coefficient: What is it? Part 2

by Tom Gaylord
Writing as B.B. Pelletier

Part 1

Last week I republished Part 1 of this discussion about ballistic coefficients because I was out of town helping my sister. I’m back in the office, but Part 2 of this report is necessary to close the loop. So here we go.

This report covers:
• Review
• Today’s discussion
• Round balls
• Conical bullets
• Smokeless powder
• A big point
• Shape
• Round balls — again
• The bottom line

I’ve taken 11 months to return to this subject of ballistic coefficients (BC). That was in spite of some tremendous interest in Part 1 of this report last May.

I’m purposely avoiding all discussion of mathematics, which is difficult, since ballistics is a discipline that heavily employs mathematics. But I’m not qualified to write about the math; and, more importantly, I know that 99 percent of my readers would be turned off if I were to write the report that way. read more
