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

  • Launch of the Benjamin Discovery

  • The lesson?

I apologize to reader RidgeRunner. I had planned to start the test of the replacement Benjamin Fortitude rifle today and I told him so yesterday. But a comment from reader Geo791 changed my mind and got me thinking about today’s report. Here is what he said.

“B.B.
Wow! You are certainly unlucky at getting good PPP airguns to review. The Urban had accuracy issues due to flashing on the baffles in the moderator. The Gauntlet has poor accuracy for some unknown reason. The Fortitude leaked air and had to be sent back. Don’t remember now what the issues were with the Stormrider but as I recall it had problems too. It’s not looking good for these price point PCPs, and the chances of getting a good one don’t appear too good either. Well, as they say, it is what it is. Too bad the Gauntlet you received was not good. Based on your findings, I would not take a chance on one. I would add that my Urban has been excellent so far.

Beeman R9 with Vortek center-latching air piston: Part 4

This report covers:

  • Important discovery!
  • Analysis
  • Setup
  • JSB Exact
  • Evaluation
  • Test restructure
  • Predator Polymag
  • H&N Field Target Trophy
  • H&N Baracuda
  • Crosman Premier
  • Benjamin Cylindrical
  • Velocity comparison
  • Retest of JSB Exacts
  • Cocking effort
  • Discussion
  • Going forward
  • Testing new designs

Today I will test the Vortek Center-Latching Air Piston in the Beeman R9, with the pressure set at 50 bar, which is 725.19 psi. This is the highest pressure to which I have set the unit, so today’s velocities should be the fastest we will see.

Important discovery!

Before we begin today’s test, a remark made by reader GunFun1 to the last report triggered some unplanned testing that revealed some surprising results. He was concerned by my remark that some spring-piston guns (and that is EXACTLY what this center latching unit is) need a “wake up” shot when they are first fired. I have seen this with perhaps half of the springers I have tested over the years. Here is what he asked me. read more

This report covers:

  • The test
  • Lead Sled
  • Rifle rested on sandbag
  • The artillery hold
  • Discussion
  • Summary

Today I will shoot my vintage HW85 at 50 yards for you. One thing I’m testing is whether resting the rifle on a Caldwell Lead Sled will improve accurate. Reader Bob from Oz says it will. We’ll see.

The test

The day was perfect for a test like this. It was 34 degrees with just a hint of a breeze. I shot in three different positions that I’ll describe as we go. The rifle is still sighted in for 25 yards, so the pellets dropped about 3 inches at 50 yards. And I used the Crosman Premier pellet that has worked so well for this rifle in the past. read more

This report covers:

  • Rob velocity?
  • H&N Finale Match Light
  • Sig Match Ballistic Alloy
  • Qiang Yuan Olympic
  • RWS R10 Match Pistol
  • Discussion
  • So, what?
  • Cocking effort
  • Firing cycle
  • Summary

Today we look at the velocity of the HW 55SF target rifle I tuned back in November. If you read Part 4 you’ll see that I just applied Tune in a Tube grease (TIAT) to the mainspring and got great results. Some readers ask me to use TIAT over and over again on different airguns, apparently not convinced that it works as well as it does. But when they break down and try it, they see for themselves. This stuff really works!

Rob velocity?

But what does it do to the velocity? This is a low-powered spring rifle and we know that thick grease can rob velocity. We have the baseline velocity data I gathered in Part 2 to compare to, so today I will re-test the rifle with the same pellets. Let’s get right to it. read more

This report covers:

  • Sig Match Ballistic Alloy
  • Smoothing makes a difference
  • RWS Superdome
  • Experience so far
  • Crosman Premier 7.9-grain pellets
  • RWS Meisterkugeln Rifle
  • Summary

Today we are back with the Beeman P1 air pistol I disassembled and lubricated in Parts 4 and 5. I said at the end of that job that I felt the gun was behaving like it had just been tuned, so instead of doing the velocity test next I would shoot it for accuracy. That would give it a chance to break in a little before velocity testing. Today is the accuracy test.

The test

I shot the pistol off a rest at 10 meters, using a 2-hand hold. My hands rested on the bag and the pistol did not touch it. I intentionally did not read the first accuracy test before shooting because I wanted to test this pistol without any bias. I also did something that I thought was very clever. Then I discovered that I had done it in the first accuracy test, as well. Oh, well, when you are old like me, everything is new each day! read more

This report covers:

  • Barreled action

  • The test
  • Summary

Many readers wanted to look inside the HW55 SF, and today is the day! This is a Weihrauch spring rifle, and it comes apart like most of them. There are a few differences that I will mention as we go. Let’s get started!

Barreled action

The first step after checking to make sure the rifle is not cocked and loaded is to remove the stock. On this rifle that means loosening three screws — one on the underside of the forearm and the two triggerguard screws. The screws can remain in the stock and triggerguard for safekeeping, but the triggerguard is removed from the stock. I’ll have something more to say about this during assembly. read more
