  • The final test
  • Discussion
  • Summary

Today we look at the accuracy of the Diana 26 I have been testing. Two things are different about this air rifle. It’s a Diana 26, which I didn’t hear of until recently and it’s a .177, which I haven’t had much luck with. So I chose 7 different pellets, in hopes of finding one or more than were accurate.

The test

I shot from 10 meters off a bench using the artillery hold, though I had to hold the rifle tighter than normal because the butt is so slippery against my shoulder. I shot 5-shot groups to speed things up, but decided I would shoot a final 10-shot group with the pellet that was most accurate. read more

  • A target rifle?
  • RWS Hobby
  • Discussion
  • Trigger
  • H&N Finale Match Light
  • Pressing in the pellets
  • Sig Match Ballistic Alloy

  • Cocking effort
  • Summary

Today I test the velocity of the new Air Venturi TR5 Multi-Shot Target Air Rifle. Reader GunFun1 has been chomping at the bit to talk about this air rifle, but he has restrained himself until I reported on it. Today I will talk about the power you can expect from a factory gun. I know from reading the comments that you readers are way ahead of me in this discussion, but I have purposely avoided reading your comments, as I didn’t want them to color my opinion of the gun.

Sometimes when I test a new (to me) airgun I read up on it before I start testing. Most of the time, though, I don’t do that. I want to experience the airgun exactly as a first-time buyer would. Not everyone reads this blog, and, of those who do, not everyone tunes and modifies their airguns. Some readers just shoot the guns the way they receive them, and I want them to know what they can expect. read more


Tuning BB’s Diana 27: Part 2

Part 1

A history of airguns

This report covers:

  • Teardown
  • 25 years?
  • Krytox!
  • Petroleum archaeology!
  • Grease to oil
  • Spring is fully scragged
  • Grease formed plugs and solidified
  • Start cleaning
  • Removing the barrel
  • Surprise!
  • Piston out
  • And rust!
  • Diana peened the blind pin in the piston head!
  • Cleaning done, time for the Krytox
  • Lubed the mainspring
  • Assembly
  • The rest of the parts go in
  • Finishing assembly
  • The verdict
  • Did I do it wrong?
  • What should I do now?
  • Don’tcha wanna know how it works?
  • RWS Superpoint
  • Air Arms Falcon
  • Summary

Today is the day we learn whether Krytox is the miracle lubricant that both fixes and quiets spring-piston airguns. I have been hounded by people for more than a decade to try this stuff, and I had dug my heels in real deep, but then it dawned on me that Gene from Pyramyd Air had been after me for an equally long time to try Almagard 3752 — the grease that turned out to be Tune in a Tube. We all know how that went!

I promised to become the number one Krytox cheerleader if the stuff really works as advertised — by some airgunners, not by Krytox, themselves. But, I will also be only too happy to poke a hole in the Krytox balloon if it turns out we have been hoodwinked. read more

  • RWS Hobby
  • Resting on the sandbag
  • Artillery hold off hand extended
  • Discussion
  • Adjusted the rear sight
  • Falcon pellets
  • Sig Match Ballistic Alloy
  • JSB Exact RS domes
  • H&N Finale Match High Speed target pellet
  • Something extra
  • Summary

Today we look at the accuracy of the BSF S54 Match rifle. Now, while this rifle is called a Match rifle and did come with a large aperture sight, it’s not a serious match rifle and never was. Sometimes I have guys ask me questions like, “Could it be used in a match?” and I have to answer, “Yes” but they don’t let me finish by saying, “… but it will never win!” You see, some guys are so enraptured by the design of the S54 Match (and that huge rear aperture!) that they want it to be a real match rifle. Other guys own one and don’t want to spend the money for something different. The bottom line is — The BSF S54 Match rifle is not for formal competition! I think you will see that today. read more

A little more of the BSF Story

Bayerische Sportwaffen Fabrik (BSF) was established in 1935. They made some airguns before WW II, but after the war is when they really got going. They were located in Erlangen, a town that’s about 15 kilometers from Nuremberg, but today is more like a suburb.

BSF airgun models ranged from youth guns to serious adult guns. Their lowest model was called the Junior that was a plain-Jane youth breakbarrel. Above that the Media came next. It shared a few parts with the Junior like the trigger but it was longer, heavier and more powerful. Think of them as the Diana 23/25. read more

  • I like the design
  • Velocity and power
  • Easy to load
  • Air Arms Falcons
  • Discussion
  • H&N Baracudas
  • Feeding
  • Summary

Today we learn about the velocity of the new Hatsan SpeedFire Vortex multi-shot rifle. As you remember from Part 1, this is a repeating breakbarrel spring-piston air rifle. The one I’m testing is a .22, but there is also a .177 available.

I like the design

For starters, I like the design of the SpeedFire’s magazine. It doesn’t sit out naked, nor does it stop you from closing the barrel after it is empty. I’m referring to many bolt-action PCP repeaters that cannot close their bolts on an empty magazine. That does prevent you from dry-firing but also forces you to remove the magazine after it is empty. I prefer to be in control of the airgun at all times. read more

  • Couldn’t get the rifle to group!
  • The double group
  • Sandbag rest
  • Wraith Ballistic Alloy pellets
  • I can do this!
  • Air Arms domes
  • Air Arms Falcons
  • Last group
  • Summary

Today I start looking critically at the accuracy of the new Sig ASP20 breakbarrel rifle. Until now I have only shot 5-shot groups. They are okay for quick work but do not tell the whole story. Today I will shoot 10-shot groups and we will learn the accuracy of this new rifle with some precision. I won’t get into the statistical reason that 10 shots are better than 5, but here is a good bottom line — anybody can get lucky, and it is far easier to do it 5 times in a row than 10.

The Whiskey3 reticle

Before we get into this test report, reader Bimjo asked this. read more
