How consistent is a multi-pump?

by B.B. Pelletier

Today, we’re going to look at shot-to-shot consistency in an airgun many consider inexpensive – the Sheridan Blue Streak. And, of course, anything I say about the Blue Streak holds true for the Silver Streak, as well. This is an experiment I read about years ago, and it’s a real eye-opener. It also gives you something to do with that new chronograph you get for Christmas.

Consistency is king!
In the world of airguns, the watchword is consistency, as in how close each shot’s velocity is to all the others in a given string. I have known shooters, and perhaps you have too, who get so wrapped up in the quest for the lowest possible shot-to-shot variation that they don’t shoot at targets anymore. They just shoot shot after shot through the chronograph, searching for a gun/pellet combination that never varies. read more


Air Shotguns, Part 5 – the Yewha

by B.B. Pelletier

Time for another installment in our continuing saga – “Air Shotguns.” We last looked at the Vincent and the Paul, two American-made shotguns from early in the 20th century. Let’s turn our attention to Korea and a much later time.


The Yewha 3-B Dynamite was an air shotgun that was imported in the 1980s – BY CHANCE!

Yewha 3-B Dynamite
If you were a Beeman customer during the 1970s, as I was, you were surprised one day to see a strange-looking airgun among the traditional German and English models. It looked large and crude, and the name – Yewha BBB Dynamite – was hardly what Beeman customers were used to. It was an air shotgun from Korea. read more


BSA Tech Star – a great hunting rifle at a fabulous price!

by B.B. Pelletier


BSA’s Tech Star is an airgun hunter’s dream!

Things are always changing at Pyramyd Air, and today I would like to look at a gun that has become a super buy – the BSA Tech Star.

Small gun packs a punch!
The Tech Star was designed to be a less expensive option for those who wanted a BSA Hornet but were on a budget.
As the Tech Star was designed, however, it became a lot more. The Hornet was designed for the UK, where the limit for air rifles without a Firearms Certificate (FAC) is 12 foot-pounds. In the UK, no matter how much an air rifle costs, 12 foot-pounds is pretty much the limit if the owner doesn’t want to go to the expense and hassle of obtaining an FAC. Among other things, one of the FAC requirements is a gun safe bolted to the structure of your house, which usually means the studs. So almost everyone has a 12 foot-pound gun. read more


Remington Airmaster 77 – just right for Christmas!

A rifle that I have passed by for some time is the Remington Airmaster 77. It’s pretty impressive when you hold it in your hands, and I think it represents a great value – especially when you take advantage of a deal Pyramyd Air is offering right now. More about that later!

Unusual looks!
This is a most unusual-looking air rifle. The stock and forearm are matte black plastic, and the receiver is matte black metal. The outer barrel is brushed nickel, which contrasts very nicely with the dark gun.

Nice open sights!
The gun comes with a scope, which I’ll get to, but there is also a very nice set of open sights. The front is a fiber optic green bead, and the rear U-shaped notch fits it perfectly! Usually, there’s a mismatch between front and rear with fiber optics, and I never know exactly where the bead should go when I sight. But, the sights on this Remington line up very naturally! The rear sight adjusts in both directions. read more


Crosman 101 multi-pump pneumatic

by B.B. Pelletier


Crosman’s old model 101 was a very successful pneumatic.

When Crosman began making air rifles in 1923, they quickly settled on an underlever design that was to be in the inventory for the next 25+ years. From 1925 into the early 1950s, the Crosman .22 caliber model 101 or “Silent,” as it’s sometimes called in advertising, was a popular pump rifle.

No model number on the gun
The 101 is a strange bird. First…there is no model designation on the gun. Second…because most parts interchange, you will find all sorts of parts variations on the guns today. Finding an original 101 is as hard as finding an original Garand rifle from World War II. And, it has the same problem: How can you prove that it’s original? read more


Walther’s Dominator does it with style!

by B.B. Pelletier

Let’s go into the high-rent district to have a look at an American-designed German field target gun – the Walther Dominator!

Based on a 10-meter target rifle
The Dominator is based on Walther’s 300 Alu Tec target rifle. The 300 Alu was the first production air rifle to use air pressurized at 300 bar, which is 4,350 psi and change. It has a regulator to lower the firing pressure to a more managable figure (probably around 2,000 psi), so what you get with 300 bar is a lot more shots. If you can’t fill it that high, the rifle will still work on 200 bar, but there are fewer shots.

The Dominator presented some challenges to the German part of the team that designed it. They thought it would be easy to convert their valve to shoot faster with heavier pellets, but that part of it took them nearly one full year. In the end, they admitted they had underestimated the amount of air needed to push a .177 10.6-grain pellet to 900 f.p.s. They were so used to pushing 8.5-grain pellets to 575 f.p.s. that this new task took them to a whole new level of design! read more


Pellet head sizes

by B.B. Pelletier

Late last week we received this question: Pyramyd lists 2 JSB Exacts in .22, 5.51mm and 5.52mm. Why? High power gun vs low power gun?

Today, I’d like to discuss the reason for different pellet head sizes.

What does a pellet head do?
A diabolo pellet only touches the bore in two spots – at the head and again at the tail. The tail is sized much larger than bore size to seal the compressed air or gas behind the pellet. But, the nose doesn’t seal anything. It acts as a guide for the pellet. It can either ride the bore, which is the top of the rifling lands, or it can ride the grooves, themselves. If a pellet is marked by rifling on the nose when run through the barrel with a rod, it is riding the grooves, which is the most common way. read more
