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.”

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.

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.

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.

The best of B.B.: Can nitrogen be used in PCPs?

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

  • The argument
  • Liability
  • So, is nitrogen dangerous?
  • Oxygen can kill you!
  • So what? We’re talking about nitrogen
  • What about other gasses?
  • Show some respect

Tomorrow is Thursday, December 24. It’s Christmas Eve. On that day I’m running a special blog that allows you readers to do most of the writing. We will all tell which airgun we would like to receive for Christmas, and I will start it in the text. Be thinking about the one airgun you want the most this year.

I realize that not all readers celebrate the Christmas holiday. But don’t let that deter you from commenting. Whether you celebrate Christmas or not, this exercise is open to all readers.

I’m running some Best of B.B. reports to give myself some time at Christmas. I have family and guests this week, and I can’t get to the computer as often as I would like. This report was first published back on January 15, 2008. I have updated and added a few things to it for today.

H&N Excite Smart Shot copper-plated lead BBs: Part 3

Smart Shot BBs
H&N Excite Smart Shot BBs are the first lead BB in 90 years.

Part 1
Part 2

This report covers:

  • The point of the Smart Shot BB
  • Colt SAA
  • The test
  • First target
  • Splatology
  • Result
  • Wood is next
  • What to do?
  • Hard oak target
  • Weight retention
  • What have we learned?

Today’s test involves a very small number of shots Yet it is captivating! Today we find out whether the H&N Excite Smart Shot copper-plated lead BBs really don’t bounce back. How timely is this, since Pyramyd Air has just listed the new John Wayne Duke single action BB revolver?

I tested these BBs against three hard targets. Two were planned and the third one popped up as the test unfolded.

The point of the Smart Shot BB

The Smart Shot BB is copper-plated lead. As such it should not rebound from a hard surface like steel BBs do. That’s is the whole point of this BB and why it is worth the money, if it really works that way. Because if it works, the Smart Shot BB allows airgunners to safely enjoy action shooting sports like Cowboy Action Shooting.

This report covers:

  • Description
  • Safety first
  • Cowboy Action Shooting
  • Rebound test
  • Velocity test
  • Accuracy test
  • Compatibility with different BB feeding systems
  • Baseline testing has been done
  • Expensive
  • Anything else?

Have you ever wanted “them” to do something so much that you talked about it to everyone? And then one day you woke up and saw “they” had done what you asked?

What do you do then?

Today we begin looking at a product I never thought I would be reviewing. It’s the H&N Excite Smart Shot copper-plated lead BB. Yes, I said a lead BB. As in, “Mother, what will you complain about, now that we can no longer shoot our eyes out?” THAT kind of lead BB!

Description

Little boys used to buy lead BBs for their BB guns many years ago. But in the 1920s lead was taken off the market and the BB changed to steel. Lead BBs are good for shooting in antique BBs guns and for collecting, but if you buy BBs today, they are all going to be steel. Until now.
