Never run out of bullets

The first part of this report didn’t receive that many comments, but those who did say something said similar things. The first was you all want this gun to never run out of BBs. You want it to get no less than 150 shots before it’s time to reload.

When I was a kid I wanted the same thing. I wanted all my guns to hold an infinite numbers of bullet, so they would never run out. Then I went into the Army and got to shoot many fully automatic weapons. I quickly learned that the first thing you want in a machine gun is reliability.

I remember that the M85 .50 caliber machine gun that was designed for fitting inside the turrets of armored vehicles was the worst machine gun to exist since the French Chauchat of WWI. It jammed all the time and seldom would fire an entire belt of ammo without stopping. You had to lubricate the cartridges with fireproof hydraulic oil to keep the gun operating. read more

  • Pellets jamming
  • Trigger pull changed
  • Sig Match Ballistic Alloy
  • RWS Superdome

  • RWS Superdomes through the magazine
  • Discussion
  • Surprise!

Today is accuracy day for the Diana Chaser air pistol. I threw in some extra tests just for fun. This should be interesting, so let’s go!

The test

I shot off a sandbag rest at 10 meters. I used the single shot tray for the first 4 groups, then switched to the magazine for the final group. There were some interesting results that I couldn’t have predicted.

Qiang Yuan Match pellets

I shot the first group with Qiang Yuan Match pellets. No particular reason for that, other than I had them ready. They hit the target low and to the left, but I left the sights where they were and shot all 10 pellets. They landed in a group that measures 1.052-inches between centers. This was larger than I had hoped for the Chaser. read more

  • JSB Exact 8.44-grain dome

  • Shot count
  • Report
  • Discussion
  • Summary

Today is the day we find out about the velocity of the Diana Chaser air pistol. There are a couple other things to learn today, as well. Let’s go.

Trigger

The first thing I wanted to know was whether that trigger really is adjustable. So I got a fine Allen wrench and started adjusting. Turning the screw in the trigger blade counterclockwise did nothing at all. The pull remained where it was — two stage and around 4 lbs.

Then I turned it in — clockwise. Bingo! I got to the point that the gun couldn’t be cocked. That tells me the trigger is adjustable and also that the adjustment works on the sear contact area. I had to back the screw out several turns and then I got a single-stage trigger that fired at 8 ounces. That’s FAR TOO LIGHT for an inexpensive direct sear! I kept turning and testing until I got a great 2-stage pull. Stage one is 12 ounces and stage two breaks cleanly at 2 lbs. 4 oz. The trigger can’t be “bumped off” which is important for a light trigger — especially one that has a direct sear adjustment. I’m staying where I am. read more

  • CO2 chamber
  • More CO2
  • HOWEVER
  • Sights

  • Evaluation
  • Summary

Okay, Bob, this one’s for you! Several readers have asked me to test the new Diana Chaser air pistol, but my brother-in-law, Bob, has been the most vocal. Not that he wants to buy a pistol — he is interested in the Diana Chaser air rifle that is built on the same frame. Today I’m starting the test of a .177-caliber Diana Chaser air pistol. Both the rifle and pistol come in .177 or .22 caliber.

Chaser rifle

The Chaser rifle comes with everything you need to convert it into a Chaser pistol. The owner’s manual describes how that is done. At this time I think that is the only way you can go. I don’t see the parts needed to convert the pistol into the rifle. So, the rifle and pistol combination together seems like the better deal than just the pistol by itself. Unless price is an issue. Give that some thought before you buy either gun. read more

Hellboy semiautomatic BB gun: Part 3

The Hellboy BB gun is a realistic semiautomatic repeater.

This report covers:

  • The test
  • Air Venturi Steel BBs
  • Adjusted the sights
  • Hornady Black Diamond BBs
  • Dust Devils
  • Discussion
  • Summary

Today we look at the accuracy of the new Hellboy semiautomatic BB gun. Let’s get right to the test.

The test

I shot the Hellboy off a UTG Monopod rest at 5 meters. I said in Part 2 that if the gun was accurate enough at 5 meters I would extend the range to 10 meters for another test. We will see today if that is going to happen.

Reader GunFun1 wanted a video of me shooting at a can, but that’s not interesting for several reasons. First, if the can is missed the viewers have no idea by how much. And hitting a soda can with a BB gun doesn’t show up well on film. It’s better in person. But if the Hellboy is accurate enough, I have a plan for how to do what GF1 wants. read more

Ten-meter accuracy test — Daisy 499 versus Haenel 310

A history of airguns

This report covers:

  • Another failure!
  • The test
  • 499
  • Discussion 1
  • Haenel 310
  • Discussion 2
  • CZ75 P-07 Duty accuracy at 10 meters
  • Summary

I put today’s report in the historical section because it relates to both the Haenel 310 and the Diana model 30 that we tested recently. In the comments to the Diana 30 test the question was raised about which would be more accurate at 10 meters — the Daisy 499 Challenger or the Haenel model 310. I said I thought the 310 would beat the 499 because it is rifled, but several readers wanted to see. So, today we see.

Another failure!

Before I get to the results of today’s test, let me fill you in on another irony. I was going to test the accuracy of the Benjamin 700 today and the gun jammed as I started to shoot. This one has a happy ending, because I got it unjammed and working again, but that was after today’s test. There is more sweet irony in the story that unfolded there, but I will hold off on that until we get to the report. read more

This report covers:

  • ASG Blaster BBs
  • Trigger blade is curved
  • Smart Shot BBs
  • Hornady Black Diamond BBs
  • Sight adjustment
  • Dust Devils
  • Summary

Today is accuracy day for the ASG CZ 75 P-07 Duty BB pistol, and I think you will be surprised. I know I was.

The test

I shot this BB pistol from 5 meters off a UTG Monopod rest. I started out badly, getting such a large 10-shot group with ASG Blaster BBs that I frankly did not believe it. I noticed on the last couple of shots that I wasn’t concentrating on the front sight and I thought that might be the reason for the poor showing. I decided to give ASG BBs a second chance.

ASG Blaster BBs

I’m so glad I did try a second group, because I shot much better this time and also I learned what caused the problem. It wasn’t the sight like I thought, though that was a part of it. This time the CZ75 P-07 Duty put 10 BBs in 1.455-inches. The group is well-centered but low on the target. That means the pistol is sighted to shoot to the aim point, because I was using a 6 o’clock hold. read more
