  • Air Arms Falcons
  • H&N Finale Match High Speed pellets

  • Summary

Today I test the accuracy of the Webley Mark VI with battlefield finish. I decided to test it with all 5 pellets that were used in the velocity test.

The test

I shot from 10 meters, using a sandbag rest for the butt of the revolver. I held the gun with two hands for a steady hold. I shot 6 pellets at each target and I will describe what happened as we go. Let’s get started.

JSB Exact RS

The first pellet I tested was the JSB Exact RS. The first three shots landed low, with one below the target paper. The group had to come up somehow. read more

Zulu!

“Front rank fire; rear rank fire! Advance! Rear rank fire! Advance…!” So goes the volley fire scene in the epic movie, Zulu. That movie is based on the true story of the British Army defending Rorke’s Drift (a ford in a wide stream) in January of 1879, when 3,000 to 4,000 Zulu warriors attacked just more than 150 British and colonial troops and tried to wipe them out. Just the day before at the Battle of Isandlwana, 20,000 Zulu warriors had killed over 1,300 British troops. read more

  • The breech test
  • Second tune with a new piston seal
  • The hand test
  • No relief
  • Rear sight was fooled with
  • Too much air escapes the compression chamber
  • Where we are
  • Summary

This is the report about tuning reader Michael’s Winchester 427, which we know is a Diana 27. It’s a .22 caliber breakbarrel air rifle.

New breech seal

I completed the tune in Part 6 and then started shooting the rifle to burn off the excess oil from the piston seal pre-lube. I expected one or two explosions after the tune, but the rifle never stopped detonating. It was constant. Something was wrong.

The breech test

The rifle acted like it was leaking air at the breech. There is a way to determine whether the breech seal leaks. Put something light, like tissue paper, over the breech and see if it gets blown off by escaping air. I did that and the paper stayed in place when the rifle fired. So the breech seemed to be okay. read more

A history of airguns

This report covers:

  • Taking the gun apart
  • BB gun spring compressor
  • Help!
  • No air tube
  • What does this mean?
  • BB gun technology
  • What to do?
  • Summary

Today I tear into my Daisy Number 12 model 29 single shot BB gun to see what’s wrong with it. If you recall, I was testing this gun last August when it stopped shooting altogether. I was testing it for velocity when it simply stopped shooting a BB out the barrel, so I removed the single shot tube and extracted bits of what I knew were leather.

Daisy model 29 leather stuff
This stuff came out of the Daisy Number 12 model 29. It’s leather that has rotted and come apart.

When I saw that junk I knew what had happened. The leather piston seal, which in a Daisy BB gun is called a plunger seal, had rotted and was coming apart. It had to be fixed, before the gun could work again. read more

This report covers:

  • Clarification
  • Hatsan Vectis
  • Nova Star
  • Hatsan Speedfire
  • Air Venturi M1 Carbine
  • The stock
  • The rear sight
  • Summary

Clarification

This report is about the first day the SHOT Show 2019 was open. I must begin with a clarification. The Sig MPX PCP I reported yesterday has a name I never mentioned. It’s called a Virtus. I visited the Sig booth this morning because my pictures of the guns taken at the range weren’t that good, and that’s when I learned the name. So, It’s a Virtus that we are waiting for.

Virtus
The new Sig PCP is called the Virtus.

Hatsan Vectis

I started the day at the Hatsan booth, where Hatsan’s Cecil Bays showed me the new Vectis lever action PCP repeater. It’s available in .177. 22 and .25 with magazine capacities of 14, 12, and 10 shots, respectively. The lever both cocks the rifle and advances and feeds the next pellet. It runs on 200 bar air pressure (2900 psi — hurrah!) and gets 29 foot-pounds, 38 foot-pounds and 40 foot-pounds, respectively. read more

  • Summary

And I’m going to pick it up right where we left off on Friday. A reminder that I am in Las Vegas at the SHOT Show today and will not be able to respond to comments as easily as normal. Let’s get started.

Assembling the ball bearing cages

We have come to the most daunting part of the assembly — assembling the trigger unit. You have to put a swarm of loose parts into the spring tube under tension from both the mainspring and the trigger spring. First, put the lubricated spring guide into the rear of the mainspring. I forgot to do that the first time through and I assembled the rifle without the guide. Got the rifle all buttoned up and said those famous last words, “I hope I never have to do THAT again!” Then my eyes fell on the guide sitting on the table. It was smiling at me, and I’m pretty sure I heard God laugh a little! read more

Many of you have been reading this series in which I tune reader Michael’s Winchester 427 that is actually a Diana 27. This is not an air rifle for beginners to learn on! The mechanism is too complex for first-timers for a number of reasons that should become clear today.

SHOT Show

I have to tell you — this is a very lengthy report. I won’t get it all done today, so Monday I will finish up. And on Monday I will be in Las Vegas at the SHOT Show. I won’t see your comments as frequently as usual while I’m there next week, plus after I walk out of the show every day I have to go back to my room, write the next day’s blog and have it ready to publish by 9 p.m. which is midnight on the east coast where the WordPress server publishes the blog. So please don’t ask me any lengthy questions. I am not going to have dinner with anyone this year, so I can do my work without being whipsawed! read more
