  • 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

  • Something else

  • 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

  • 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

  • Summary

I’m starting a report on the BSF S54 target rifle today. I reviewed this rifle 4 years ago, but I want to look at it more thoroughly this time.

BSF

Bayerische Sportwaffen Fabrik (Bavarian Sporting Weapons Manufacturer) or BSF, as it was known, operated for several decades, both before and after World War II. They were based in Erlangen, Germany, a suburb of Nuremberg. The guns they made were approximately equivalent in quality to Dianas, though in some respects like power they were ahead for a few years. It was BSF that first broke the 800 f.p.s. barrier with their model S55/S60/S70 breakbarrel. I group those models because they were all the same except for their stocks — kind of like the S54 we are looking at today. read more

Today we are back with the Diana model 50 underlever spring rifle, shooting at 25 yards. I have a couple things to tell, so let’s get started.

Low light

First, my quartz light that I always us to illuminate the target was on the fritz, so for all of today’s shooting I illuminated the target with a powerful flashlight. It wasn’t ideal, but I believe it worked okay. I learned one thing for sure — I need a backup quartz light!

I remembered to switch the front sight post to the large square-topped one that’s best for target shooting. I wouldn’t have that as an excuse for poor marksmanship! read more

  • Summary

We start looking at the accuracy of the .177-caliber Diana model 50 underlever today. I say start because I want to shoot this rifle a lot more. I will look for interesting ways to do that.

Before we begin…

However, before I jump into the accuracy there are a couple things I need to clear up. Reader Halfstep asked about the loading tap. It was shown in the closed position in Part 2 and he asked if I could show it open. He also wondered how far into the tap the pellet falls, so I’ll show that, too.
