Diana 27
My .22 caliber Diana 27 is actually a Hy Score 807.

Part 1

A history of airguns

This report covers:

  • RWS Superpoint
  • RWS Superdomes
  • Crosman Premier
  • Am I satisfied?
  • Cocking effort
  • Trigger pull
  • The ball bearing trigger
  • How to adjust the ball bearing trigger
  • Summary

Today we look at the velocity of my vintage Hy Score 807 breakbarrel air rifle that you now know is a Diana 27. Besides that I will test the trigger pull, the cocking effort and I will tell you how to adjust the ball bearing trigger. That, alone, is worth what you paid for this entire blog, so settle in and let’s have some fun!

RWS Superpoint

The first pellet I tested was my go-to pellet for a .22 caliber Diana 27 and many other old air rifles — the RWS Superpoint. I believe that Superpoints have such thin skirts that they seal the bore better in these lower powered spring rifles. I told you about the lithium grease “tune” I did about 20 years ago. It’s still performing well after all this time, and I never oil the leather piston seal. As I recall, the Superpoint averaged around 475 f.p.s. in the past. Today 10 pellets averaged 468 f.p.s. The spread went from a low of 458 to a high of 474 f.p.s., which is 16 f.p.s. So, the rifle is still pretty much where it has always been. At the average velocity this pellet generated 7.05 foot pounds of energy at the muzzle.

Part Four

Today we start looking at the new Diana Stormrider PCP. Though this one snuck up on us, it’s getting a lot of attention now. That’s because of what it is.

What it is

The Stormrider is a precharged pneumatic (PCP) repeater that comes in both .177 and .22 calibers. It’s produced in China to Diana’s specifications. The biggest news is it retails for $200. I remember a time 5 years ago when many people thought that was impossible, yet here we are.

What it isn’t

Here is where the native drums are getting it wrong. The Stormrider is not a threat to the Benjamin Marauder. It doesn’t have the highly adjustable trigger, the sound suppression, the ability to vary the fill pressures or the ability to adjust the power. If it challenges anything it’s both the Benjamin Discovery and the Benjamin Maximus, but I’m not sure it even does that. Both those rifles fill to 2000 psi and the Stormrider fills to 2900 psi, and that is a make or break difference. If someone plans to use a hand pump, the Benjamins are the way to go. If they use a tank, the Stormrider excels because it’s a repeater. Assuming, of course, it is accurate.
What it also is not is a thousand-dollar PCP. Mention those three letters and people who don’t shoot them assume infinite accuracy. None of the comparison rifles mentioned above have that and I doubt the Stormrider does, either. My task will be to see just how accurate it is.

Umarex Legends MP40 BB Submachinegun: Part 2

Part 1

This report covers:

  • CO2 effect
  • Installing CO2
  • Loading
  • Umarex steel BBs
  • Fire control
  • The sensation
  • Daisy BBs
  • Hornady Black Diamond BBs
  • Shot count
  • Hornady Black Diamonds — again
  • Bottom line

Today we look at the velocity of the new Umarex Legends MP40 BB Submachinegun. Since it has a semiautomatic mode, this will be easier than expected. However, there are special considerations for a gun like this.

CO2 effect

Most of you know that CO2 chills the gun as it is fired. And CO2 loses pressure as the temperature drops. Will that affect the velocity of this full-auto airgun? I plan to test for it. My test will show the velocity you can expect from the gun at its fastest and also what will happen as the shots happen faster and the temperature falls. There are unlimited ways of doing this, and I have selected one.

The Defender super carbon fiber tank carrier

This report covers:

  • 2017 Texas airgun show
  • Why a carrier?
  • I can make it myself
  • Fabric carrier
  • Who makes it?
  • What about those saddlebags?
  • Pockets — pockets and more pockets!
  • Center of balance
  • Will Pyramyd Air carry it?
  • The cost?

Today is not about an airgun or a shooting technique. Today I’m writing about a carrier for the 98 cubic foot carbon fiber air tank I recently bought from Pyramyd Air. That tank is one of the handiest pieces of equipment I own. At the Texas airgun show it filled three Benjamin Wildfires all day long and still had over 3,400 psi when I brought it home! It’s as important to me as the spotting scope I bought from Meopta last year. I wrote 4 reports about that scope, but I think I will only write this one about the carrier. It’s neat, but you will get the idea really quickly.

Part 1

A history of airguns

This report covers:

  • Crosman Premiers
  • RWS Superdomes
  • H&N Baracuda Match with 5.51mm heads
  • Top speed?
  • Hobbys
  • Firing cycle
  • Cocking
  • Trigger pull
  • Evaluation so far

Today we learn how powerful this smooth-shooting .22-caliber HW85 is. You may remember from Part 1 that I bought this rifle because of its super-smooth tune. So, let’s get right to it.

Crosman Premiers

The first pellet to be tested was the 14.3-grain Crosman Premier. These loaded easily and averaged 678 f.p.s. The range went from 672 to 693 — a spread of 21 f.p.s. At the average velocity this pellet produces 14.6 foot pounds. This was so close to the “magic” velocity of 671 f.p.s., where the weight of the pellet in grains equals the muzzle energy in foot pounds. I mention that because it’s just a handy thing to know.

This report covers:

  • Who to believe?
  • Quart of blood!
  • How do you know what you don’t know?
  • Make haste slowly
  • There is more than one way…
  • Setting the bevel
  • Most important point
  • World-record sharpener
  • Bad advice that turned out well
  • Artillery hold?
  • Three ways to sharpen.
  • That’s all, folks!

I didn’t think I would be back to this subject so soon, but I’ve had some major breakthroughs recently that I wanted to report before I forget them. As you may recall, I am writing this report because I want to experience what it feels like to be a new guy in a subject that interests me, but one that I know very little about. That way maybe I can better understand what new guys want/need to know about airguns. I had no appreciation of how much of a new guy I was when it came to sharpening straight razors, or just how deep I would get into this new subject!

  • Why this airgun?

Here is an airgun we have all been waiting for since the SHOT Show — the Umarex Legends MP40 BB Submachinegun. PAY ATTENTION! There are two versions of this airgun at this time. One is the weathered one that comes with a leather sling. and the other is a blued steel gun that apparently has no sling. I asked for the weathered one because of what this is — a battle-ready WW II replica. Beautiful bluing belongs on replicas of Colt Pythons, not on guns that have served in war! There is a price difference of $50 between the two offerings as this is published (the weathered version with the leather sling is more), but I would watch them because I think that’s will change from time to time.
