This report covers:

  • What kind of rubber?
  • Remove the old rubber
  • Measure the old rubber
  • Loops on each end
  • Install the new rubber
  • Ready!
  • Daisy BBs
  • Problems!
  • Got it going
  • Baseline
  • Shortened the rubber
  • Second Daisy test
  • Dust Devils
  • Two lessons
  • Shortened the rubber again
  • Higher velocity
  • Shortened the rubber another time
  • Last test
  • Summary

Today I install a new rubber band in the Johnson and if all goes well, we will see what velocity it gives. In case you forgot, when I got this gun the rubber was broken.

Rubber
This is how I got the gun.

What kind of rubber?

I have been shooting my other Johnson Indoor Target Gun for years, so I had 10 feet of 3/16” amber surgical tubing on hand for repairs. I will start with that.

I had this surgical rubber tubing from my other Johnson.

Remove the old rubber

Step one was to remove the old rubber from the gun. It might look easy, but wherever that rubber was in contact with the steel in the gun it had bonded. It took me 15 minutes to get all the little pieces out. read more

This report covers:

  • The test
  • Hobbys
  • Sig Match Ballistic Alloy
  • H&N Baracuda Match
  • Falcon
  • Discussion
  • Summary

Today I test the Benjamin 310 BB gun with pellets. We learned in the test of BBs that the gun does like to shoot with the larger BBs. Let’s now find out how that translates to pellets.

The test

I shot the gun off a sandbag 10 meters from the target. I used the plus one pumping routine that worked so well for BBs. That works like this — the gun has air remaining from the previous shot and I pump one time after each shot. I get a stable velocity with that routine. Let’s see what she will do. read more

  • Operation
  • Cocking
  • Trigger
  • Serendipity
  • Pat is not pending
  • Adjustable sights
  • Repeater
  • Summary

I was going to write about something else today, but the response to Friday’s report convinced me to stick with the Johnson. Several of you said that you enjoyed the detailed photos. Today I will tell you about how the gun is constructed and how it operates, plus some special features. Grab your coffee cup and let’s go!

Operation

The Johnson gun is a catapult gun, and in Part one I showed you the broken surgical tubing in my new gun. Now, take a look at a gun with tubing in working condition.

This is how the rubber is supposed to look when it’s properly installed. The ends of this surgical tubing are held together with small cable ties. We are looking at the inside of the top cover of the gun. read more

This report covers:

  • Who was Johnson?
  • The M16
  • Airgun
  • The gun in hand
  • Discussion
  • Summary

Yes, I’m reviewing a Johnson again. For some reason I keep coming back to this one. I did a short piece on December 28 2015, and before that an article on December 22 2005. Finally I did an initial very short introductory piece on October 2, 2005. That’s a lot of articles. So, why am I writing about it again? Well, the gun we are looking at today is a nearly-new Johnson that I got in the box at the Texas Airgun Show this year. It has many thing that I can show you, plus I will do a complete report on this one. So grab your coffee, boys — this series should be good. read more

This report covers:

  • How to test?
  • RWS Hobby
  • H&N Baracuda Match
  • One pump
  • Another test
  • Fastest shot
  • Pellet tests coming
  • One final test
  • Summary

Today is our final day of looking at the velocity of the Benjamin 310 multi-pump BB gun. You will recall that the reason this has taken so long is because this gun is very flexible about the ammo it accepts. If it turns out to be accurate, this gun may well be an all-time best airgun to own — right up there with an FWB 124 and a Diana 27..

Today we will look at the velocity with pellets. Since the gun is smoothbore I don’t expect it to be accurate past 10 meters, but I will reserve judgement until we test it. If I get nothing better than 2-inches at that distance, though, I won’t be testing it at 25 yards. There are already enough holes in my walls and woodwork! read more


Sharpshooter rubber band catapult gun: Part 4

A history of airguns

Sharpshooter pistol
The Sharpshooter catapult pistol was made from the early 1930s until the 1980s by as many as 5 different companies. This one was made in the early 1940s.

This report covers:

  • The test
  • Test 1
  • Test 1 continued
  • Discussion
  • Firing behavior
  • What’s next?
  • Test 2 — A modern Sharpshooter
  • More discussion
  • Summary

Today we look at the accuracy of the Sharpshooter catapult pistol. Since there is only one type of ammo for it, I have added something additional to spice up the report. Let’s get to it.

The ad from 1948 said the pistol could hit a fly at 16 feet. Dean Fletcher tested his at a more reasonable 10 feet, which is what I will do. Readers asked me what kind of target I used and today I will tell you. Using a coat hanger, I made a wire target holder that stands up, and wrapped a single sheet of aluminum foil around the edges of the loop at the top. It’s the same target I used for the Daisy Targeteer test. read more

This report covers:

  • Smart Shot

  • 4.45mm balls
  • Beeman Perfect Rounds
  • Darts and bolts
  • Airgun darts
  • Bolts
  • Airgun bolts
  • Bolt extraction
  • Not finished yet

Today I will almost complete the velocity test of the Benjamin 310 BB gun. Today we look at the velocity with lead balls and also with both kinds of darts. Lead balls are first.

I don’t plan on testing each lead ball exhaustively. If I find something interesting I can always expand that particular test. And I will exhaust all the air before each shot I record, so you know it is moving that fast on just those pumps.

Smart Shot

H&N Smart Shot measure 0.1725-inches, nominally. Here is their performance. read more
