Benjamin Legacy with a gas spring was a short-lived breakbarrel.

This report covers:

  • Something special from the back room!
  • Benefits of a lower-pressure gas spring
  • Trigger
  • Lower power
  • RWS Hobby pellets
  • Crosman Premier pellets
  • JSB Exact RS pellets
  • The point of this review

Something special from the back room!

I’m going slow with this report, because it concerns an airgun you cannot purchase. Read Part 2 to see where I found out about the .22-caliber Benjamin Legacy breakbarrel with a gas spring — not the Legacy with a steel spring that sold many years earlier. In the 3 months between the time I contracted pancreatitis in March of 2010 until I was discharged from the last hospital in June of that year, the Benjamin Legacy with gas spring was born, died and forgotten. I never had the chance to review it for you.

This report covers:

  • Baracuda Match pellets, 4.50mm head
  • Baracuda Match pellets, 4.53mm head
  • RWS Superdome pellets
  • Fast action
  • Learning the trigger
  • JSB Exact heavy pellets, 10.34 grains
  • The bottom line — so far

Let’s start looking at the accuracy of the Diana 340 N-TEC Classic rifle. I used the open sights that come on the rifle, and I shot at 10 meters today. I did that because air rifles with gas springs are, in my experience, not all that accurate. I did feel the 340 N-TEC is a different breed of gas-spring rifle, but I wanted to play it safe. So, 10 meters off a rest.

Baracuda Match pellets, 4.50mm head

The first pellet I shot was the H&N Baracuda with a 4.50mm head. It hit the target a little high and to the left; so, after shooting the group, I adjusted the sights.

This report covers:

  • Cocking effort

  • H&N Baracuda Match pellets, 4.50mm head
  • RWS Superdome pellets
  • Why the slow shots?
  • Trigger
  • Evaluation so far

Cocking effort

Today, we’ll look at the velocity of the Diana 340 N-TEC Classic air rifle. I said in part 1 that cocking this rifle is a chore for 2 hands, but I’ve learned something about the gun in this test. The gas spring isn’t the only thing I’m fighting to cock the rifle. The barrel pivot joint is also a bit too tight. The cocking effort is about 35 lbs, which isn’t that bad, but the pivot joint boosts that up to 42 lbs. It made the rifle difficult to measure, but I soon learned to rapidly pull down the barrel and bypass the pivot joint tension. Then, it is a one-handed operation.

Interesting gun designs — Benjamin Legacy: Part 2

Part 1

This report covers:

  • Something special from the back room!
  • Easy to cock
  • Smooth shooting
  • Testus interruptus
  • No more Legacy
  • Something’s coming — maybe
  • The rifle
  • Cocking effort 16 lbs.
  • A modern Diana 27?

Today’s report is the reason I wrote the whole report about interesting designs. Today, I’m going to address what I’ve wanted to show you for the past 5 years. This is an interesting story, so fill your cup, sit back and enjoy.

It began in 2009, when Paul Capello and I started the television show American Airgunner. We needed content for the show, and the Crosman Corporation in East Bloomfield, New York, invited us to come in and film their operation. I had toured parts of their plant before, and I knew there was a lot to see.

Something special from the back room!

During the tour, their head engineer, Ed Schultz, asked if we would like to see something special. Naturally, we were excited! He took us out a back door next to the bulk CO2 tank that fills all the cartridges they make. Then, he told us about a secret project of his.

This report covers:

  • What is the 340 N-TEC Classic?
  • Gas-spring advantages and disadvantages
  • The rifle
  • Sights
  • Trigger
  • Shooting impressions
  • Overall impression

Let’s begin our look at Diana’s gas-spring guns. Specifically, we’re testing the Diana 340 N-TEC Classic in .177 caliber. The serial number of the rifle I’m testing is 01583666.

I’m very cautious when testing spring rifles that have gas springs, because dozens of past tests have made me skeptical over the years. The claims for smooth shooting almost never pan out. The claims for accuracy are often inflated. The cocking effort is often played down when I find it to be a major influence in how easy it is to operate the gun.

I’ve seen fewer than 10 air rifles with gas springs that I could recommend to others. So, as I look at this rifle, I’ll be looking from the vantage point of a lot of past experience.

Pistons and sears

by Tom Gaylord
Writing as B.B. Pelletier

This report covers:

  • Two basic types of pistons
  • Center-latched pistons
  • Side-latched piston
  • See the difference?
  • Gas springs

I’m going to look at how triggers interact with pistons in spring guns today. I thought some of the blog readers may not be aware of some of the subtleties of sears and triggers as they relate to pistons.

Two basic types of pistons

Spring pistons are latched or “caught” by their sears in 2 different ways. These 2 ways are so vastly different that they dictate what types of triggers will work with what types of pistons. Until you understand the differences, you can’t appreciate why certain triggers such as the Rekord won’t work with certain types of pistons.

Center-latched pistons

A center-latched piston has a rod in its center that in some way gets latched or “caught” by the sear. When it’s latched, the sear restrains the full force of the mainspring. That can be well over 100 lbs. of force in the case of a coiled steel spring, or several hundred psi of gas pressure in the 2-piece expanding cylinder of a gas spring. The sear prevents the piston from moving until it’s released by the action of the trigger.

Umarex Fuel air rifle

 

That’s right! The Umarex Fuel carries its own bipod legs tucked against the forearm until you deploy them.

This report covers:

• Scope upgrade
• H&N Baracuda Match pellets
• JSB Exact Heavy pellets
• Air Arms Falcon pellets
• Artillery hold: Better or worse?
• Evaluation

I last looked at the Umarex Fuel air rifle on September 19 — almost 2 months ago. I promised you a Part 5 with an upgraded scope, and today we’ll look at it. I learned an important lesson today about the Fuel that you need to know if you’re considering buying one.
