  • Discussion
  • Summary

Today is the first day I test the accuracy of the new Diana K98 Mauser PCP.

The test

I shot the rifle with open sights off a sandbag rest from 10 meters. I shot 5-shot groups so I could test more pellets.

Trigger adjustment

I said in Part 2 that I would adjust the trigger today, so let’s get to it. There is just one screw to turn and clockwise decreases the sear engagement. I turned the 2mm screw clockwise as far as it would go and then tested the trigger by hand. It felt lighter and had less creep than it had before the adjustment. My trigger pull gauge records the 2-stage pull as still breaking at over 12 pounds. It is still creepy, though not as much as before. And that’s that. read more

Seldom has a day like this happened in this blog — and I mean that in the best possible way! This is going to be a biggie!

Start testing accuracy

Today we start testing the accuracy of the Air Venturi Avenger that I’m testing. So far the Avenger has stood up very well and I have been hoping that it’s as accurate as everyone seems to say. Well — it is! I have a lot to tell you, so let’s get started.

Bug Buster 3-12X32

I have been thinking about this test for a long time and wondering which scope to mount. The Meopta Optika6 is the best scope I own and would do very well on this rifle, but the Avenger is a lightweight PCP. How about a scope that’s suited to the concept of light weight? I mounted the UTG Bug Buster 3-12X32 on the rifle and it seems ideal to me. read more

Part 1

This report covers:

  • Fill
  • JSB Exact Jumbo Heavy
  • Fill to 200 bar
  • Discharge sound
  • Discussion 1
  • Beeman Kodiak
  • Pellet feed with the single-shot tray
  • H&N Hollow Point
  • Discussion 2
  • Trigger pull
  • Summary

Today we test the velocity and power of the Diana K98 PCP rifle. According to the description on the Pyramyd Air web page, this is a 26-foot-pound air rifle in the .22 caliber I am testing. This information helps me select the right pellets to test. A pneumatic in this power range is probably best with medium-weight to heavyweight pellets, though I will also test lightweights, just so we know.

Fill

I tried to fill the rifle to 200 bar/2900 psi — the recommended fill pressure, but I waited an instant too long to shut the tank valve and the fill went to 3,000. It’s only 100 psi more. read more

Part 1
Part 2

This report covers:

  • Adjust the reg.
  • What’s next?
  • Beeman Kodiaks
  • JSB Exact Jumbo Heavy
  • Velocity
  • Baracudas on the lowest setting
  • JSB Exact Jumbo Heavy on the lowest setting
  • Dae Sung on the lowest setting
  • Discussion
  • A special test
  • Shot count
  • Trigger adjustment
  • Summary

Today I lower the regulator pressure setting and see what kind of performance we get with the Air Venturi Avenger. Because the regulator is user-adjustable and the hammer spring is also adjustable, the Avenger is flexible in its power settings. Today I hope we will determine the lower limit of that range, but because of the hammer spring adjustment there is a lot more to test. I will tell you everything I do, but I may not be able to test each and every possible combination, if the regulator settings and hammer spring adjustments have too wide a spread.

Adjust the reg.

First things first. Before you adjust the regulator you must first exhaust all the air in the reservoir. I read the manual carefully before proceeding. I was surprised that the Allen wrench that was included with the rifle wasn’t the right size for the air bleed screw. The wrench they sent is 2.5mm. It adjusts the hammer spring tension fine. We did that in Part 2.  But the bleed screw needs a 3mm wrench. read more

This report covers:

  • Another great one?
  • History
  • Sights
  • This PCP
  • Fill
  • Repeater
  • Lightweight
  • Realism
  • Adjustable trigger
  • Oh, yes they did!
  • Stuff in the box
  • What do we have?
  • Summary

BB’s going to rant, just a little. We airgunners ask for realistic replica airguns all the time, and then we gripe because they are TOO real! I don’t know if you remember, but I was so impressed by the spring-piston Diana K98 air rifle that I bought the test gun. I knew it was a re-skinned Diana 460 Magnum — a springer I don’t particularly enjoy for its hard cocking — but the realism of that re-skinned rifle was and is astounding.

Another great one?

Well, having just pulled the Diana Mauser K98 PCP rifle out of the box I have to say that I believe Diana has done it again. This K98 PCP is very realistic. So I did something I usually avoid. I read the reviews. There were only two and both of them criticized one of the most realistic parts of the rifle — the rear sight! They were upset that it doesn’t adjust for windage! Well — guess what? The rear sight on the K98 firearm also does not adjust for windage! What did you expect — a Corvette that has 4 doors and a cargo hatch so you can store your groceries better? Come on, guys — a Corvette is a sports car and a K98 Mauser is a battle rifle from World War II. I guess the only thing that would be funnier would be to watch an airgunner pull the trigger on an 8mm K98 firearm and learn what real recoil is! I can tell you this — I had to get rid of my M48 Yugo Mauser because I could not take that kick! Okay, the rant is over. read more

Part 1

This report covers:

  • Test strategy
  • Why was it showing higher?
  • Adjusting the regulator
  • Are you following this?
  • The test
  • Beeman Kodiak pellets
  • The regulator
  • JSB Exact Jumbo Heavy
  • Beeman Kodiaks
  • The last string
  • Trigger pull
  • Summary

Test strategy

Today I will begin the velocity test. The Air Venturi Avenger is so adjustable that it will take several reports to cover just the velocity. Not only is the hammer spring adjustable — the regulator is, as well. In fact, that presents a challenge for how I will test the rifle. The rifle came out of the box with a charge of 3,600 psi and the regulator set to 3,000 psi. That means that until the internal pressure falls below 3,000 psi, the pressure that the valve “sees” will always be 3,000 psi. That is the highest pressure to which the regulator can be set — at least accurding to the manual. read more

To tell the complete story I first have to tell you some bad news. I want you to read it without getting angry, because if it hadn’t happened as it did I would not be able to tell you the extraordinary news I’m about to tell you.

Accuracy day

This report was supposed to be the first test for accuracy. I knew there were going to be several accuracy tests, but this would be the first one. Except the rifle didn’t cooperate. read more
