Synthetic-skirted (saboted) pellets and accuracy

By B.B. Pelletier

Today’s posting is an answer to a question from one of our readers:

I heard saboted pellets don’t work very well in some airguns because of the barrel being choked. Is that true?

Can a synthetic skirt be accurate?
I can only give you my personal observations on this question, plus the scant material I’ve read and seen. I’ve not had good luck achieving the same level of accuracy using pellets with synthetic skirts (what our reader and some manufacturers refer to as sabots) as I have with homogenous, pure lead pellets. Ten years ago, synthetic-skirted pellets were not very accurate at all. They were relatively new to the airgun scene and certain manufacturing problems I’ll discuss in a moment weren’t properly addressed. read more

Tokyo Marui VSR-10 G-Spec MG315

By. B.B. Pelletier

Tokyo Marui may make the finest airsoft guns in the world, but they aren’t real good at naming them! The VSR-10 G-Spec MG315 is REALLY a military sniper rifle, that looks a lot like the U.S. Army’s M24. Based on the Remington 700 bolt-action rifle, the M24 is a wonderful rifle for sniper duties and our subject gun is perfect for airsoft players.

It’s so SMOOTH!
If Marui ever needed a poster child for quality, this is the one. This spring-piston gun is butter-smooth. The ease with which it cocks is forgotten when you squeeze the trigger and note the calm shooting behavior. If pellet rifles could be made this smooth, people would buy them – I don’t care what velocity they had! It’s a shame that many players will feel the need to beef up the powerplant, because they will no doubt say adios to such smooth behavior as I have never seen in a spring airgun. read more

More on muzzle velocity and energy

By B.B. Pelletier

I received the following question posted as a comment to my May 18 posting, What about Eun Jin pellets? I thought this question deserved a better answer than just a few lines in the comment section, so here it is.

I keep noticing the reference to foot-pounds of [energy] when talking about the force needed for certain ammo. All airguns I read about are usually rated in muzzle f.p.s., or I see a reference to calculating foot-pounds with a particular round.

Do airguns have an “unloaded” foot-pounds-of-pressure [rating] to go by?

I ask because I purchased a Winchester 1000B from Pyramyd Air, and I cannot find a reference to its foot-pounds. Wonderful weapon, by the way. read more

Are longer barrels more accurate?

By B.B. Pelletier

How long must a barrel be to be accurate?
There is no answer to that, because short barrels are JUST as accurate as long barrels. That’s today’s post in one sentence.

I just overheard an airgunner asking his buddy how much more accurate he thought a longer barrel would be for his AirForce Talon SS. As I listened, the two of them hypothesized about all sorts of accuracy influences that don’t really matter or even exist.

Proof that a longer barrel doesn’t increase accuracy
You can explore the accuracy versus barrel length controversy right here on the Pyramyd Air website. Let’s start with a look at the Drulov DU-10 target pistol and the Drulov DU-10 Eagle target rifle. The rifle has a barrel twice as long as the pistol, yet there is NO discernable difference in accuracy. The rifle has a higher velocity as a result of a longer barrel, which means it can shoot farther than the pistol, but it does not group any better at 10 meters. Both are made for 10-meter target shooting and both are equally accurate. read more

Warm weather means hotter velocities for CO2 guns!

By B.B. Pelletier

Shooters in Florida, the Southwest and Hawaii don’t worry much about cold weather, but the rest of us do because the winter puts an end to outdoor shooting with CO2 guns. Now that summer is back in almost every corner of the US, all of us can head outside again for loads of powerful CO2 shooting!

Many of you may already know that warm ambient temperatures can increase velocity in a CO2 gun. How? Because CO2 evaporates at higher pressures as the air temperature increases. As the air temperature increases, CO2 is warmed and more pressure is achieved inside the CO2 container. And, as you know, higher pressure means more power! read more

Bad vibes

By B.B. Pelletier

Today we’ll look at a problem some spring guns have in abundance – too much vibration!

What causes vibration in a spring gun?
Vibration is caused when the moving parts of the powerplant have too much clearance. The moving parts include the piston with its seal, the mainspring, the spring guide and sometimes other parts – such as the piston liner (inside the piston), which removes some of the clearance between the mainspring and the piston wall. Technically, this last part isn’t supposed to move, but if it gets bent during operation it can cause vibration.

Do powerful guns vibrate more?
More power isn’t really an indicator of a tendency to vibrate. In fact, some very powerful spring rifles hardly vibrate at all. Gas-powered piston guns, such as the Beeman RX-2, are among the smoothest, as far as vibration is concerned, though it may take a little time to get used to the quicker recoil. read more

The BB pistol that didn’t shoot BBs

By B.B. Pelletier

We’re surrounded by hundreds of BB pistols today. There seems to be no end of models from which to choose, but it wasn’t always that way. In the 1930s, the first American BB pistol was a very different kind of airgun.

The Daisy Targeteer was on every kid’s wishlist!
Daisy’s Targeteer was initially offered in 1937. It came in a cardboard box with the pistol, instructions, a metal tube of special shot (we’ll get to that in a moment) and spinner targets. The box converted into a backstop that held the spinners so they could be shot safely. All this cost just $2.00!

The first Targeteer was blued & had fixed sights.
