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

History of airguns

This report covers:

  • Start
  • Scope base off
  • Tip 1
  • Mainspring
  • Remove piston
  • Sleeved piston
  • Threaded spring tube
  • Breech seal
  • Cleaning
  • Piston seal
  • Tuning strategy
  • Trigger
  • Insert the piston with the new Vortek seal — tip 2
  • Last thing — the trigger box!
  • Final assembly
  • Summary

Today I disassemble the Beeman R10 and install the Vortek PG3 tuning kit. I installed one of these in the Air Arms PG3 SHO tuning kit in an Air Arms ProSport last year and the results were very positive. But this R10 is a different rifle in many ways, and I will cover that today as we go.

I am going to show you all the differences and nuances of the R10, but I can’t show everything about disassembly. If you want to see that read the 13-part series titled Spring gun tune. That was about a Beeman R1, but most of the steps are the same for the R10. I will address the ones that aren’t. read more

  • Comparisons

  • Summary

Some of you may have been hoping for Part 2 of the Beeman R10 rifle report today. Well, Part 2 will be the strip-down and installation of the Vortek tuning kit, and I need a couple days to do the work and take the pictures, as well as the writing. So today I’m starting my report on the Slavia 618 breakbarrel pellet rifle.

History

Guess what? Almost nobody knows the history of this air rifle. It has a lot of fans, but nobody seems to know much about it.

The Blue Book of Airguns says it was made in the 1970s — period. But they say the same thing about the Slavia 622. Well, I received one of those as a gift in about 1961 or ’62, so that’s obviously not right. read more

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


What do you want?: Part 1

This report covers:

  • So what?
  • The most important thing
  • What gives accuracy — the barrel
  • What gives accuracy — the trigger
  • Safety
  • What gives accuracy — the breech lock
  • Powerplant
  • Sights
  • My idea
  • Between the lines

This is the start of a series that I think will be quite different. The inspiration comes from the SpaceX company that has now successfully put two astronauts on the International Space Station. SpaceX has significantly reduced the cost to build rockets and launch payloads, making space exploration more affordable. Elon Musk determined that he could buy the materials to build a rocket for just three percent of what the Russians wanted for theirs. That was what put him in business.

So what?

What does any of that have to do with airguns? Everything, I think. Because it illustrates just how much can be accomplished when there is a plan and when the schedule is not artificial but is based on realistic forecasts. This report is not meant to criticize any company or person, but it will also not permit the hardening of attitudes that stifles progress. read more

Today we conduct the first accuracy test for the AirForce Edge 10-meter target rifle. This is the first accuracy test of at least two, because of some things I will tell you in the report.

Up to speed

As a reminder this rifle came to me highly modified and shooting with twice the power of a standard Edge. I tested it thoroughly in that configuration, then I converted it back to the factory Edge specification. The links to all those reports are at the top of the page in case you want to catch up. read more
