  • Sight in
  • At 10 meters
  • At 20 meters
  • Raise the sight
  • Summary

Today I shoot the Umarex Air Javelin at 20 meters with a dot sight that has been sighted in. You finally get to see the sort of accuracy that I saw at the SHOT Show in January. The range there was set up for about 25 yards and it seemed like the arrows all went to nearly the same place! You will see that today.

Quick review

Part 4 was a test with a dot sight too, but I also tested the Umarex CO2 adaptor that allows you to use two 12-gram CO2 cartridges. Unfortunately the Tasco Pro Point dot sight I used for that test could not achieve the elevation that was needed to hit the target at 20 meters. I also shot wide of the target bag when I shot an arrow that had been damaged in the rear from a Robin Hood. I didn’t know it was damaged until I pulled it from the fence and examined its base. read more

  • Falcon domes
  • Gamo Match
  • RWS Meisterkugeln Rifle
  • JSB Exact Jumbo
  • RWS Superpoint
  • Summary

Today we test the Slavia 618 breakbarrel’s accuracy. I have described the rifle in Part 1, and in Part 2 we tested the velocity before and after it got a freshened breech seal. The one I’m shooting today could be considered a “hot” 618.

The test

I shot the rifle off a rest at 10 meters. Even though I tested 7 different pellets I shot 10-shot groups because the rifle is so light and easy to cock. Let’s get started.

RWS Hobby

The first pellet I tested was the RWS Hobby wadcutter. Right off the bat during sight-in I determined that the 618 does not like to be rested directly on the sandbag. I suppose it is so light that the force of the piston throws the rifle off target when it fires. The rifle is so small that it’s difficult to hold with the artillery hold, but I did the best I could. Ten Hobbys went into 0.91-inches at 10 meters. read more

  • 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

This report covers:

  • More to test
  • What are the holes for?
  • Remove the old 88-gram cartridge
  • Lots of gas!
  • Install the adaptor
  • Cock the gun!
  • Don’t do as BB does!
  • Adjust the dot sight up
  • Discussion
  • Summary

Today I shoot the Umarex Air Javelin with a dot sight optic. My UTG Reflex Micro  Dot was mounted elsewhere so I mounted a Tasco Pro Point red dot sight. 

Air Javelin dot sight
The Air Javelin accepted the Tasco Pro Point without a problem.

More to test

I didn’t tell you this but I asked Umarex to send me a 12-gram CO2 adapter so I could test the AJ with 12-gram cartridges. Some readers had asked about that possibility and since Pyramyd Air doesn’t carry the adapter, I went straight to Umarex.

Air Javelin 12-gram adapter
Several Umarex airguns including the Air Javelin use this adapter that switches the power source from 88/90-gram CO2 cartridges to 12-gram cartridges.

  • RWS Basic
  • How does it shoot?
  • Crosman Premier Light
  • Discussion 1
  • Re-test with the “new” seal
  • Basic test 2
  • Premier Light test 2
  • Discussion 2
  • Cocking effort and trigger pull
  • Summary

Today I test the velocity of the Slavia 618. You will recall that I have two of these rifles and one seems to be performing well. That’s the one I’ll test. The other rifle I will rebuild, but we will look at that in a separate report some time in the future.

Before the test

This rifle has a leather breech seal which is indicative of a leather piston seal, as well. So I dropped about 5 drops of Crosman Pellgunoil down the barrel and stood the rifle on its butt for a few days to let the oil run down into the compression chamber and soak into the leather. It also soaks into the breech seal as it passes, softening it up so it can do the job it was designed to do. That should get the rifle into the best possible condition for a velocity test. read more

  • Today’s test — the firing cycle
  • JSB Exact 8.44-grain
  • How I set up the Vortek kit
  • Air Arms Falcon
  • RWS Superdome
  • Cocking effort
  • Summary

Today is the day we find out what the Vortek PG3 SHO tune has done for the Beeman R10 I’m testing.

Recap

I received the rifle from a reader who wanted a rifle that had a tune done by me. I will tell all of you now that I am not an airgun tuner. I tune some of my own guns from time to time, but I don’t do it as a service. And there is absolutely nothing special about any tune I have done. This report is more a testimony of what the Vortek kit can do than it has anything to do with me.

The reader and I both agreed that a smooth-shooting air rifle was preferable to the last f.p.s. in velocity. So smoothness was what I was after, and nothing more, as long as the rifle performed within reasonable parameters. read more

Today we’re going to have a little fun. I know some of you would like to work on spring-piston airguns but you just don’t want to jump into the deep end of the pool — as in buying expensive tools like a mainspring compressor and parts that may or may not work as you expect. Today we are going to change the mainspring in the SigAir ProForce MCX Virtus AEG airsoft gun, and we will do it with two Allen wrenches — nothing more! This is a job any of you can do. Then we’ll test the velocity of the gun and see what impact the new spring has made. read more
