SHOT Show

I’m at the SHOT Show today. Today is Media Day At The Range, so I’m looking at all the new airguns that are on the range in Boulder City. Yesterday I went to Sig Range Day, so tomorrow I will have a report on both events. The show opens on Tuesday, so the Wednesday blog will be my first report from there.

Today we look at the velocity of the Diana 27S we are testing. If you recall, in Part 2 the breech seal failed and I couldn’t test the rifle. I replaced the seal with a temporary leather one and the velocity jumped from the mid-300s to the high 600s. I said then that it was the largest velocity increase I have ever seen from just replacing a breech seal. I expected a gain of 60-80 f.p.s. Several readers made similar comments. read more

A history of airguns

This report covers:

  • Velocity day
  • A happy accident
  • Breech seal
  • No problemo!
  • BB isn’t daunted
  • Problemo
  • BB has a backup
  • HOWEVER
  • What size are the seals?
  • What now?
  • Cocking effort
  • Trigger pull
  • Today’s report
  • Summary

Today is Part 2 of my test of the vintage Diana 27S. From the comments to Part 1 we learned that several of you own them, but you all seem to live in Europe and the UK. This model is very rare in the U.S. Today’s report is about a failure that turned out to be a huge success!

“Oh, oh! BB’s talking like Mr. Miyagi again! Better get out the rags and car wax!”

Velocity day

I normally test velocity on Day 2 and that is exactly what I intended to do. My guess was that a .177-caliber Diana 27 should shoot around 650 f.p.s. with lighter pellets when it’s in good condition. I put five drops of Crosman Pellgunoil down the air transfer port that is located behind the barrel when it’s closed and then I shot three shots to just spread the oil around. Normally I would cock and uncock the rifle to spread the oil, but we learned in Part 1 that the 27S has an anti-beartrap device that prevents uncocking except by firing. read more

Today we start looking at the accuracy of the Gamo Swarm Fusion 10X Gen II repeating breakbarrel spring-piston air rifle. I’m hoping for a great result!

Today’s test

The Swarm Fusion has open sights, and I’m testing them today. It also comes bundled with a scope that I will test in another report. Since this is the first accuracy test, I decided to just shoot 5-shot groups so I could test lots of different pellets. Let’s get started.

The test

I shot off a sandbag rest at 10 meters. I used a modified artillery hold, because the thumbhole stock on this rifle doesn’t permit a classic hold. The only difference is I did grasp the pistol grip. read more

A history of airguns

This report covers:

  • Carel
  • Diana 27S
  • Anti-beartrap
  • Description
  • Dimensions
  • Sights
  • Ball bearing sear
  • History
  • Parts interchange
  • Summary

This report is one I wanted to write months ago, but after all I wrote about reader Michael’s Winchester 427 and my own Diana 26 and Diana 35, I thought I had better let vintage Dianas rest for awhile.

Carel

I purchased this Diana 27S along with the Diana 26 and Diana 35 I have just mentioned from reader Carel of the Netherlands. He gave me a fantastic deal on three air rifles that are quite uncommon in the US. The 35 is the most common of the three, but Carel had a very early one that was different than the one many Americans have seen, so it was just as uncommon to me as the other two. read more

What the new year holds

I know a lot of you are trying to peek behind the curtain, to see what’s coming down the line. Some writers will divulge things, but I won’t. I would rather wait and see how something is presented before I announce it to the world.

But that doesn’t mean I don’t know some of the things that are coming. Today I would like to share a glimpse into the coming year with some things I know and also the trends I see unfolding. Let’s go!

Big bores

The coming year will be a hot one for big bore airguns. Expect to see muzzle energy over 800 foot-pounds, and this year it will be in actual production guns — not those that have been held up for scrutiny but have never quite made it to production. read more

Well!

When I started the report on the Gamo Swarm Fusion 10X Gen II I didn’t know I was kicking a Texas fire ant mound! Part 1 of this report lead to a report on the history of Gamo, and that brought the show to a screeching stop! I won’t get into all that transpired, but you can read the comments if you are interested.

Another breakbarrel repeater

I’m not going to defend or criticize anyone in this report. All I’m doing is testing another breakbarrel repeater for power, accuracy and overall quality as it pertains to airgunning. With that in mind, let’s start the show. read more

  • So — what’s the verdict?
  • Summary

Today I am writing about Gamo. Here is how it came about. On Tuesday we received these comments to my post about the Gamo Swarm Fusion 10X Gen2 repeater.

From Yogi

B.B.
“Well, Gamo knows how to make airguns and I’m rooting for this one to deliver on all that it promises.”
My only experience with Gamo was a piece of junk, and the pellets re not much better. What is the greatest Gamo of all time?
Maybe a Friday blog about it?
What is the best gun they have ever made? Anything worth collecting?

From Will S.

Morning B.B.,
On some rifles, not all, Gamo uses an all-polymer breech block and the pivot bolt is GLUED IN so you can’t adjust it when the barrel has side-to-side wobble. If you can’t adjust such an important part of the rifle, then the rifle will permanently lose its accuracy and will no longer be interesting to use. No more Gamo springers with polymer in place of steel for me.
