  • A great idea
  • The 160
  • Pellets were the key
  • What if…
  • The lesson
  • Not picking on Crosman
  • The point
  • QB78 is okay

I was set to report on another vintage air rifle today, when yesterday I got a superb comment that prompted today’s report. Reader reallead was responding to a comment from reader Halfstep, who was wondering about the accuracy of his QB78. Let’s look at it now.

Halfstep,
Being the owner of a QB77 I’d like to add my comments. I bought my QB77 from MAC 1 in Calif. several years ago. According to the imprinted receiver, it was made (imported?) by Sportsman Airguns. Someone told me that QBs were actually made in Korea, but I don’t know for sure since I can’t find the country where it was made anywhere on the gun. [Editor — As far as I know, the QB air rifles were all made in The People’s Republic of China.]

This report covers:

  • JSB Exact Jumbo Heavy
  • That scope level
  • Crosman Premiers
  • H&N Baracuda Match 5.53mm heads
  • Problem solved!
  • More on the scope
  • Evaluation

Today I started accuracy testing the Galahad-rifle from Air Arms. There were some surprises, so you’re in for an interesting read!

Scoped

I mounted a UTG 8-32 SWAT Mil Dot scope, using the high mounts that came with it. When I started sighting in the pellet was low and way left. I adjusted it up but it would not come anu further to the right. At 12 feet the pellet was hitting two inches to the left.

Swapped rings

So I swapped the rings, thinking that if they were drilled off-center this would correct the problem. I also shimmed under the rear of the scope, to give me a little more vertical adjustment. Alas, the pellet did strike the target higher, but as for the left-right, nothing changed. That means the issue is with the Picatinny rail on the rifle. I needed to finish the test, so I calculated where I could aim at 25 yards and still have the pellet strike the pellet trap.

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.

  • First 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.

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.
