  • 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

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

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

How to begin?

Remember me telling you I had a backlog of reports to do? This rifle that I got from reader RidgeRunner is one of them. But I need to change my report format this time because I need the AirForce Edge target rifle for another test I’m doing — the report on testing the H&N Baracuda FT pellet.

I wanted to test that pellet with an accurate precharged rifle as well as several spring piston guns, and this Edge is my most accurate PCP in .177 caliber. It’s also more powerful than a standard Edge target rifle. RidgeRunner modified this Edge by adding a firing chamber to boost the power to almost double that of a conventional Edge. A firing chamber collects and holds the compressed air that has passed through the regulator, so more air is available for the shot. Nothing has to be done to the regulator when a larger chamber is used. It simply provides more air to push the pellet — a bigger or longer push, if you will. read more

  • Tune in a Tube
  • But the rear sight…
  • The rifle is fixed!
  • Breech seal shim
  • Pivot bolt locking screw
  • Accuracy
  • Air Arms Falcons
  • RWS Hobby
  • Then I read…
  • Michael’s rifle is accurate
  • The big surprise!
  • Next

Today was a long time coming — much longer than I anticipated. But I learned a lot about problems with the Diana 27 that I have never encountered before, and I now believe I can tune one with ease.

Recap

Just so you remember, I am tuning reader Michael’s Winchester 427 that is a Diana 27 by another name. It looked good on the outside, apart from missing things like the rubber button on the butt and a locking screw for the pivot bolt. The rear sight was a kluge of backwoods “repairs”, but that didn’t impress me until the very end of the job. In fact, I will tell you now that I should have started there first. It was the main source of the rifle’s issues. read more

Diana Chaser air pistol
The Diana Chaser is a new CO2 pistol.

This report covers:

  • Mount the sight
  • Front sight?
  • Cut to the chase
  • The test
  • The trigger
  • Dialed the dot way down
  • First target
  • Second target
  • Summary

Today I test the Diana Chaser air pistol with the UTG RDM20 Reflex Micro Dot sight we have been reviewing. The last test was done with the sight mounted on a Beeman P1 back in January, and it did quite well. I told you I wasn’t going to run a special report on the sight, but instead I would be testing it on several airguns as time went by. The Chaser test is today.

Mount the sight

The Chaser’s rear sight had to be removed to mount the UGT dot sight. There is a short rail in front of the pellet trough but I didn’t think it was quite long enough for this sight base. read more

  • Summary

Well, the discussion in Part 1 ended on the topic of UFOs. Let’s see where we go today with our exploration of the velocity of the .25-caliber Hatsan Vectis lever action PCP. I will begin by addressing two comments that were pertinent. The first was from reader Willyaimright, who said he had to return his first Vectis to Pyramyd Air because he couldn’t get it to accept a fill.

Flash Vectis

Knowing that some precharged guns have to be cocked before the initial fill (i.e. when there is no air inside the reservoir), I read the manual before proceeding. It’s an unmanly act, I know, but sometimes you just gotta cheat. read more
