Where to start

Today we test the velocity of the AirForce International Orion. Many of you are new to precharged pneumatics (PCP), so let me show you how I select which pellets to test when I don’t know the airgun. I start by looking at the advertised velocity, which for this rifle in .22 caliber is said to be around 800 f.p.s. Knowing how AirForce states things like this, that number is obtained with a reasonable lead pellet, so I will guess it was a Hobby, though they might have shot something heavier. Still my velocities are going to be between 700 and 800 f.p.s. and that tells me I should start with medium weight lead pellets — something in the 13 to 16-grain range. Once we know more we can go from there.

Umarex Throttle air rifle: Part 3

Throttle
Umarex Throttle offers a lot for a little money.

Part 1
Part 2

This report covers:

  • StopShox
  • Mount the scope
  • Accuracy
  • RWS Superdomes
  • Crosman Premiers again
  • JSB RS
  • Some other pellets
  • What next?

Today we look at the accuracy of the new Umarex Throttle air rifle. You may remember that I was very pleased with the performance of this new air rifle, up to this point. If it is also accurate, we have a winner.

StopShox

This rifle contains the StopShox mechanism that takes the sting out of shooting a gas spring. That unit works, because the Throttle definitely does not sting.

Mount the scope

The Throttle came with a 3-9X32 scope and 2-piece scope rings. The Throttle has a Picatinny rail they call the LockDown mounting system. It’s mounted to the top of the spring tube, and the rings are Weaver, so mounting the scope was fast and easy. The optics are clear and this scope has AO (adjustable parallax) that adjusts down to 10 yards.

A history of airguns

This report covers:

  • No front sight
  • The test
  • Beeman Silver Jets
  • Sheridan Cylindricals
  • Crosman Premiers
  • About the same
  • Velocity
  • Variable pumps with Crosman Premier pellets
  • Stability
  • Conclusion

Well, after the last session when the pump mechanism and valve seemed to be fixed I was all set to start testing the Sheridan Supergrade for accuracy. The first thing I did was hoist the rifle to my shoulder, to see whether I could see the front sight through the rear peep. Oh no! I couldn’t see it! So I switched shoulders and looked with my left eye. Oh no! I couldn’t even see it with that eye — the eye I have been calling my good eye. Was there even a front sight on the gun?

A history of airguns

This report covers:

  • Wise council
  • A special technique for old multi-pumps
  • Is it holding?
  • Test one
  • How is the pump lever?
  • Test 2 — stability
  • Conclusion

Today I’m recovering from the cataract surgery, but I wrote this on Wednesday, so I was still functional. What I thought I would do is try a little experiment that could work. If it does, I will have found a new technique for restoring an old Sheridan Supergrade. Read Part 2 to learn why this multi-pump is so different from all the others.

Wise council

Before I begin, following Part 2 of this report I heard from airgunsmith Tony McDaniel of TMac’s Airgun Service in North Carolina. Tony is the guy who hosts the North Carolina Airgun Show each year (it’s on Oct. 20 & 21, 2017), and the registration form plus show info is on his website.

Why can’t “they” get it right?

A history of airguns

This report covers:

  • 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:

  • Scoped
  • Swapped rings
  • 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.
