  • Sig Match Ballistic Alloy
  • Why so much better?
  • Finale Match Light again

  • 10-meter rifle?
  • Summary

I said the next step with this BSF S54 was a teardown and lube tune with Tune in a Tube, but I changed my mind. The front sight insert I bought from Chambers arrived and I wanted to give it a go first. I’m glad I did, as you will learn later on.

Insert

Remember, I told you that T.W. Chambers in the UK has some front sight inserts for the S54? RidgeRunner wondered if there was an aperture or ring insert for the front and I thought there might have been, so I looked. Sure enough there was and I ordered one.

The new ring insert, left, will circle the black bull and hopefully give a more precise aim point. read more

This report covers:

  • The deal
  • What is it?
  • Earlier model 26
  • Blue Book of Airguns
  • Trigger
  • Stock
  • Description
  • Sights
  • Comparison to the 27
  • Summary

I have written a lot about Diana air rifles over the course of this blog. A quick look finds 2 articles about the Diana model 25, and 6 articles about the Diana 27. There are probably more on each rifle, but they may be titled so I can’t find them. While I have written a lot about these Diana models, I never heard of the Diana 26 until reader Carel from the Netherlands told me he had one.

The deal

Back in February I mentioned on the blog that I would like to find a Diana model 35 to detune, just to see how sweet it could be. Carel contacted me and told me he had a nice old one I might like. Then he told me about this model 26. I had never heard of it, and he tells me they are quite scarce in Europe, too. I think the gap between the models 25 and 27 was too narrow to support another model. read more

This report covers:

  • Something else
  • Rear sight has to come off
  • 1950s design
  • Assemble the rifle again
  • Install the peep sight
  • Ordered a new target front sight insert
  • Accuracy
  • The test
  • H&N Finale High Speed
  • H&N Finale Match Light
  • Discussion
  • Summary

Today will be another accuracy test of the BSF S54 Match rifle. But it’s a test with a twist. In Part 3 we learned which pellet does best in this rifle — the H&N Finale Match High Speed — a 7-grain wadcutter that is no longer being offered. I have received the current Finale Match Light target pellets, so I can start testing with them today, as well.

Something else

And, there is something else. A couple weeks back reader Kevin alerted me to the fact that the seller in Bulgaria from whom I bought the Diana peep sight also had a BSF peep sight for sale. He had it advertised for Anschütz, FWB and Walther, which is why I never noticed it. The price was reasonable and, as before, the shipping was free, so I ordered it. It’s here and I would like to show it to you. read more

  • Hatsan response
  • Good data
  • Velocity Baracuda Hunter Extreme
  • String two
  • String three
  • Discussion
  • Vortex Supreme
  • Air Arms Field
  • Newboy Junior
  • Firing cycle
  • Cocking effort
  • Trigger pull
  • Summary

Today we resume our look at the .22-caliber Hatsan Speedfire Vortex multi-shot rifle. In Part 2 I got some velocities that seemed far too low, so I assumed the rifle was damaged in some way. I returned it to Hatsan and asked them to look at it and, if possible, please repair it so I could resume the test with the same rifle.

Daniel Settle of Hatsan got back with me and here is what he said.

Hatsan response

Tom,

We took some time to test out your sample SpeedFire this afternoon.  This was tested “as-is” out of the box – original gun, original magazines.  We did experience a larger extreme spread with one magazine (41) versus the other (23) with our Vortex Supreme pellets.  The “bad” magazine had some damage around the pellet exit opening on the muzzle side of the body.  I expect this might be interfering with and damaging the pellet skirts as they are pushed through. 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

  • 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

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
