  • 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

  • The deal

  • Diana peep sight

  • Ebay

  • My 27
  • RWS Superpoints
  • Air Arms Falcons
  • Discussion
  • Summary
  • Sad news

Today’s report isn’t quite what the title says. I am going to tune my Hy Score 807/Diana 27 for you, because, after the success I had with Michael’s rifle, I felt it was time to strike while the iron is hot. But reader comments entered the picture as I was extolling the virtues of Tune in a Tube. One reader said he had his best luck with a lubrication product called Krytox, and then several more readers piled on, saying similar things. So, the subtitle of this report could be “The Great Krytox Experiment, or Krytox versus Tune in a Tube.” Because that’s what I plan to do — tune my Diana 27/Hy Score 807 with Krytox to compare it to a Tune in a Tube tune. read more

  • Cocking effort

  • Summary

Why no single-shot tray

I am usually sensitive to the questions of my readers, but in Part 1 I missed it completely. Reader HawkEye asked why the Hatsan Proxima doesn’t come with a single shot tray. I ignored his first comment, thinking he was just joking, but he persisted so I finally answered him. I said this.

“This rifle isn’t made to be shot single shot. No tray because it doesn’t work that way. Cocking is too hard and the loading space too confined.”

And I wondered why he would even ask such a question, until it dawned on me that he couldn’t envision the scale. I had shown him an enlarged picture of the feed probe and, looking at that, he could see plenty of room to load a pellet. read more

Slavia 618

This is my original 55 year old Slavia 618 in its new “firewood” stock. I made this one in a “camo” style, using cherry and maple blocks in a random arrangement of the pieces.

Finishing the finishing

We’ve covered theory, materials, carving the stock, personalizing it and the preparation for finishing. This is where people get anxious and start rushing to be done – that’s a bad approach. read more

  • 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

  • Made for hunting
  • Safety features
  • Trigger
  • Power
  • Summary

Today we begin our look at the Hatsan Proxima undelever repeater. As you may recall, I was testing the Hatsan Speedfire breakbarrel repeater, and it had a problem in the velocity test. That rifle is now back at Hatsan for repairs, so I thought why not look at the other Hatsan springer that’s a repeater — the Proxima, which came out in early 2018 and was a contemporary of the Gamo Swarm Maxxim?

Description

The Proxima is an underlever spring-piston repeater that uses a gas piston for power. It’s available in .177, .22 and .25 calibers and I am testing a .22. The circular magazine holds 14, 12 or 10 pellets, depending on the caliber. The cocking effort is listed as 45 lbs. for all three calibers, so this is a big boy air rifle. read more
