This report covers:

  • It’s a wrap
  • Constraining the possibilities
  • Filling the rifle
  • Test 1 — JSB Exact Jumbo Heavy 18.13 grains
  • Test 2 — H&N Baracuda Match pellets 21.14 grains at medium power
  • Test 3 — H&N Baracuda Match pellets 21.14 grains at high power
  • Test 4 — Dae Sung pellets 28.6 grains
  • Test 5 — JSB Exact Jumbo Heavy on power setting 3
  • Conclusion

It’s a wrap

I’ll wrap up the velocity testing of the Air Arms Galahad PCP today. This is when we find out how well it handles longer pellets. That’s always a concern when a rotary magazine is involved.

Heavier pellets are usually longer pellets, and weight is what generates energy in a pneumatic. PCPs are most effective with heavy pellets. To get the most power from this airgun you’ll want to shoot the heaviest pellet you can — as long as it is also accurate.

Tyler Patner from Pyramyd Air also told me that the Galahad does well with JSB pellets. I wanted to try them anyway because I felt they would be very accurate, but Tyler added that the 18.13-grain JSB Exact Jumbo Heavy dome is also very consistent. He said his testing revealed a maximum spread of 15 f.p.s. over 60 shots for this pellet when the rifle was set on power level 3 — if he remembered correctly.

BB’s Christmas gift: Part 2

Sheridan Supergrade right
Like all Supergrades, my new rifle is graceful and attractive.

Part 1

A history of airguns

This report covers:

  • The test
  • Pump head may need adjustment
  • Compare to the other Supergrade
  • The other Supergrade
  • Test 2 — stability
  • Four pumps
  • Sick old girl!
  • Test is suspended

Today we look at the power of my new Sheridan Model A, also known as the Supergrade. My low-serial-number rifle was probably made in the 1940s. The wood has certainly been refinished. The rifle seems to function fine, though today will be the very first time I have tested it over a chronograph.

I had pumped the rifle twice when I put it away, and it had held the air when I started this test. That’s a good sign.

The test

I decided to perform my standard test on the rifle, starting with an assessment of the velocity/power at each pump stroke, from 3 to 8. For this test I used .20 caliber Crosman Premiers that are no longer available. It was very revealing.

This report covers:

  • What we know
  • What I want to see
  • First string
  • Second string
  • Third string
  • Fourth string
  • Fifth string
  • Sixth string
  • Seventh string
  • Analysis
  • Out of time

Today I continue testing the velocity of the Galahad rifle from Air Arms. I told you in Part 1 that this rifle is complex and will require a lot of testing before moving on. Not only does it have a 5-position power adjuster, it also has a regulator, that adds an additional level of complexity.

What we know

In Part 2 we learned where the power bands are at each power setting. For example, we saw that the lowest power setting is virtually unusable, giving velocities with .22-caliber Crosman Premier pellets below 300 f.p.s. Power settings 2 through 5 are quite useful though. I find power setting 3 (Premiers average 749 f.p.s.) to be idea for general work outdoors and setting 2 (Premiers average 539 f.p.s.) is ideal for indoors. At those settings the spread of velocities was 14 f.p.s. and 15 f.p.s., respectively. That’s where the regulator comes into play.

A history of airguns

This report covers:

  • Crosman Premier
  • RWS Superpoint
  • JSB Exact Jumbo
  • Whadja get?

Today we look at the accuracy of the .22-caliber Benjamin 392 with pump-assist. I tested the rifle at 10 meters off a rest using the open sights that come with the gun.

Crosman Premier

We will begin with Crosman Premier pellets, that I expect to be one of the most accurate in this rifle. Shot one landed high on the bull at 11 o’clock, so I left the sights where they were.

Ten Premiers made a group measuring 0.577-inches at 10 meters. It’s not the best I have ever done at that diostance, but for a 392 it’s acceptable.

This is my last chance to wish you a Merry Christmas, but I decided to give you an early gift. Today I will test the Sharp Ace Pan Target velocity, and you can talk about it all weekend!

First test

For the first test I chose RWS Hobby pellets. This is the velocity test and Hobbys are one of the lightest lead pellets around, so they are ideal. Obviously you wouldn’t compete with Hobbys, though their accuracy could surprise us.

In this test I will pump the gun a specified number of strokes and record the velocity. I thought I would start with 3 pumps, but when I saw the velocity produced from just 3, I knew I could start with less. I tried a single pump but the pellet remained in the barrel, so 2 strokes turns out to be the minimum.

Galahad
Air Arms Galahad PCP in walnut is a striking looking air rifle!

Part 1

This report covers:

  • Power adjustable
  • Power setting 5 (high)
  • Power setting 4
  • Sound level
  • Power setting 3
  • Power setting 2
  • Power setting 1 (lowest)
  • Where are we now?
  • Extremely consistent
  • Fill probe
  • Trigger pull
  • Cocking and loading
  • More velocity to test

Today we begin looking at the velocity of the Galahad-rifle from Air Arms. This one has the longest barrel and should produce the maximum power available with this model in .22 caliber. Before we get to the mostest and the fastest, though, let’s learn the basics.

Power adjustable

The Galahad has a power adjustment knob with 5 settings. I want to establish what each of them will do. Remember two things: first, this rifle is filled to 250 bar and second, it has a regulator. So the first thing I will do is look at 10 pellets at each of the power settings. I will use the same .22-caliber Crosman Premier pellet for all power ranges.

  • Pump-assist pump effort
  • Sheridan Blue Streak pump effort
  • How it feels
  • Velocity test 1

  • Velocity test 3
  • Velocity test 4
  • Velocity test 5
  • Trigger pull
  • Conclusion

Today we look at velocity and some other things that relate to the pump mechanism of the pump-assist Benjamin 392. We will start with the effort to pump the gun.

Pump-assist pump effort

In the past I have used the chart supplied by the pump-assist manufacturer, Bob Moss, to show the pump effort of the pump-assist Benjamin 392. Today I actually tested it, by pumping the gun on my bathroom scale. I know an analog spring bathroom scale is not an accurate test instrument, but it should give us a basis for comparison, because I will also measure my recently rebuilt Sheridan Blue Streak.
