  • 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


Sig Sauer Spartan BB pistol: Part 2

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

Part 1

This report covers:

  • Install the CO2 cartridge
  • Velocity with Daisy BBs
  • Recoil
  • Air Venturi Copper-Plated BBs
  • H&N Smart Shot lead BBs
  • Trigger pull
  • Shot count
  • Evaluation so far

Today we look at the velocity of the Sig Spartan BB pistol. The specs rate it at 410 f.p.s. Today we find out. I will also comment on things like the blowback and the trigger. Let’s get started.

Install the CO2 cartridge

The first step is to put a fresh CO2 cartridge in the gun. It goes into the grip, of course. Lift off the left grip panel and then pull the mainspring housing from the back of the grip. That is the lower flat part of the grip that’s has a coarse raised pattern in the metal for a better grip. In the 1911 firearm, it houses the mainspring, but on this BB pistol it’s the lever that pierces the CO2 cartridge. read more

This report covers:

  • Sig firearms
  • The airgun
  • Manual safety
  • Full blowback
  • Grips
  • Finish
  • Sights
  • Trigger
  • Magazine
  • Light rail
  • Evaluation

Today we begin looking at Sig Sauer’s latest BB pistol, the Spartan. It’s a faithful copy of their Spartan 1911 firearm, which has upgraded features that put it ahead of many production 1911s. And it’s made in Japan.

Sig firearms

I will say this about Sig firearms — when they decide to make something they don’t cut corners. I never had much contact with them in the past, but since they have started making airguns I have been giving their firearms a look, as well. I am a died-in-the-wool conservative when it comes to firearms. Don’t try to sell me on a process like metal injection molding (MIM) unless it performs better than machining in some way other than just the cost to manufacture. read more


Do pressure vessels become unsafe over time?

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

  • Do pressure vessels become unsafe over time?
  • Operating pressure
  • Water leading to rust
  • Oxygen!
  • Danger through work-hardening
  • Last word

Today we have a safety issue to examine. Here is the question I got last week that spawned this report.

“Wasn’t sure how to reach you so using this venue. Was wondering about safety issue on pcps with regard to repeated pressurization over the years.Most pcps are newer and certainly built with margin of safety, but is it possible as these age and perhaps are handed down that they (the pressure vessel) can become unsafe? Read somewhere repeated pressurization can lead to eventual metal fatigue (in relation to high pressure vessels of non air rifle type). Thinking of future owners down the road. Thanks for all you do for all us airgun fans, read blog everyday.” read more


Hatsan Gladius .177 long: Part 2

Part 1

Hatsan Gladius
Hatsan Gladius Long.

This report covers:

  • Quiet
  • A couple things
  • High Power
  • Baracuda Match 4.50mm
  • JSB Exact Heavy
  • Low power
  • Medium power setting 4
  • What to make of this?
  • Trigger pull
  • Accuracy
  • Evaluation

We’re back with the Hatsan Gladius .177 long today for the velocity test. Hatsan advertises that this rifle gives up to 90 shots per fill. You may get that many, but not on full power. This is a hunting rifle and you want hunting rifle accuracy. For me that means keeping all your shots inside an inch which is the size of the kill zone on the smaller game the Gladius is designed to take. Now, when you throw distance into the equation things get confused very fast, so my way to simplify things is to say that 50 yards is the distance at which I would like to see one-inch groups. read more

Hammerli or Haemmerli?

Before we dive in to today’s report, a word about the spelling I have used. It is incorrect. The correct spelling of the Swiss firm uses an umlaut (two small dots) over the letter a (ä). Since the English alphabet doesn’t have umlauts, in our language the letter e follows the a — sometimes kerned closely to it. The umlaut sounds like a diphthong (aha! caught you napping in English class, didn’t we?) that most native English-speakers have difficulty pronouncing. The letter e forces our way of saying it as close as English speakers can normally come to the correct German pronunciation. That’s okay, though — most Germans cannot pronounce Connecticut, and Brits all get aluminum wrong. And, this discussion is superfluous, since almost all American shooters pronounce it Hammerelli, anyway. read more


Sig MPX pellet sub-machinegun: Part 1

Sig Sauer MPX sub-machinegun
Sig Sauer MPX sub-machinegun is a heavy, solid airgun.

This report covers:

  • Wow!
  • Description
  • Match pellets
  • Back to the gun
  • Accuracy
  • Sights
  • 30 Pellets — how do they do it?
  • Manual needs revision
  • Overall evaluation

Today we begin looking at the MPX sub-machinegun from Sig Sauer. This is a different airgun, in that it is is being manufactured for, distributed by, promoted by and sold by Sig Sauer themselves. In other words, this airgun is one Sig is proud of — and in case you aren’t a firearm shooter, Sig is very proud of everything they make and sell.

I waited patiently for this gun. I know others beat me to the punch, but their enthusiasm may have caused some problems. A few guns were allowed to go out without the company’s stamp of approval. I watched as that happened and I waited until things were right. Sig tells me they are right now, so the airguns I will test for you are the ones Sig is proud to sell. read more
