Part 1

This report covers:

  • Been awhile
  • New airgunners
  • A better way
  • Doing what works
  • The point
  • Sharpening straight razors

Been awhile

Part 1 of this report was written way back in the beginning of February. I think the reason it’s taken me so long to get back to it is I titled it wrong. I will discuss that as we go, but first let me define who “they” are. In the words of comedian, Red Green, “They” are everybody who is not us. Now that that’s clear we can continue.

Part 1 was a treatise on twist rates and how they affect accuracy. As many of you are aware, I use this blog to school both new airgunners and also airgun manufacturers — who are often as ignorant of the facts as new airgunners, but cannot or will not admit it. No engineer who has just been hired by an airgun company is going to admit there is something he doesn’t know about guns! Heaven forbid! And neither is any CEO or owner of a company, because in their minds they are in a position of authority and should therefore know!

Getting started with a precharged air rifle: Part 3

Part 1
Part 2

This report covers:

  • Fill options
  • Practicality
  • Filling a big bore
  • Tank size
  • Filling a smallbore PCP
  • The point
  • Air compressors
  • Booster compressors
  • Stand-alone compressors
  • The future

I said in the last report that I would write this report on filling options for PCPs. I’m writing this for the new guys who aren’t sure which way to turn. Any way you go represents an investment, so this is something that needs to be given a lot of consideration. Hopefully this report will start a discussion of that.

Fill options

There are two basic ways to fill a precharged airgun. Either the air is introduced from a container where it is stored until called for or else it is put in and compressed as the fill is made. The first option is based on an air tank of some kind. The second is either a hand pump or a small air compressor that connects to the airgun. I will talk about both of these but first I want to discuss practicality.

Getting started with a precharged air rifle: Part 2

by Tom Gaylord
Writing as B.B. Pelletier

Part 1

This report covers:

  • Talon SS?
  • Triggers
  • Accuracy expectations
  • Scopes
  • Get parallax adjustment
  • Match the scope to the task
  • More to come

This is Part 2. In the first part I was brutally honest about the precharged pneumatics (PCP) I think are good for beginners. Now that I am doing my experiment about learning to sharpen straight razors I appreciate the level of information most new guys are seeking and are able to accept. There will always be some folks who don’t get it the first time around, but I won’t talk down to the rest of you to cover that. I will answer their questions and explain in greater detail as they require.

Talon SS?

Reader Cal raised an issue in Part 1 and answered it at the same time. Why didn’t I put AirForce rifles like the Talon SS into the entry-level category? Can’t someone who is new to precharged airguns shoot one of those? Of course they can! The Talon SS is no more difficult to learn to operate than any other PCP. The reason I held off is the style of the rifle.

Part Two: The Hatsan Sortie PCP pistol

Part Three: The Hatsan Sortie PCP pistol

Part Four: The Hatsan Sortie PCP pistol

This report covers:

  • What is it?
  • Power
  • Presentation is important
  • Semiautomatic!
  • Description
  • Sights
  • The action
  • Silencer?
  • Evaluation so far

Today I will do the impossible. It’s not perpetual motion and it’s not levitation. Today I will scoop myself! Today I will start a report on something I was hoping to surprise you with in Part 3 of the Texas Airgun Show next week.

I haven’t reported on all the dealers who were at the show yet, and Hatsan is one I planned to cover next time. Well, I figured you needed to see an airgun after all these other reports, so I opened a large box Hatsan sent me recently and, lo and behold, inside there is an airgun I hadn’t heard of before seeing one at the airgun show — the Hatsan Sortie.

Part 1
Part 2
Part 3

This report covers:

  • The issues
  • Things I like
  • Recoil Reducing Rail
  • The scope
  • Sight in
  • First group
  • Second group
  • Third group
  • The best hold
  • Evaluation and summary
  • 2017 Texas Airgun Show
  • Pyramyd Air Cup

Big day, today. We learn whether the .177 Gamo Swarm Maxxim multi-shot rifle I’m testing is accurate, or not. You may recall in the last test that the scope was the big issue. The one that comes with the rifle isn’t very clear and I attributed at least half the group size in the last test to that.

The issues

There are two issues to examine today. This first is that scope I just mentioned. The second is what kind of hold the Swarm likes. Several owners have said their Swarms like to be held firm — not with the artillery hold. A couple say it doesn’t seem to matter which hold you use. I will try holding the rifle firmly today and we will see how that affects things.

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.

They have the wrong twist rate!: Part 1

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

  • Then came big bores
  • What am I talking about?
  • Bullets don’t work like pellets
  • Bullet length
  • Why bullet diameters matter
  • Hard cast lead bullets
  • Putting all of this together
  • Last story

Before we begin I have some startling news from Umarex USA. Sales manager, Justin Biddle contacted me and told me the new Hammer big bore is regulated.! I certainly did not know that, because this is huge news. It means that those three shots it gets on a fill can all be at the same power level. I have adjusted the SHOT Show report (Part 6) to reflect this new information. And by a strange coincidence, this dovetails nicely with today’s report.

For many years I have written about black powder firearms in this blog, and I have included things like rifling twist rates in those articles. And for years people have written me comments that they appreciate a look at something different, but they would never consider shooting black powder arms or even modern firearms, themselves.
