This report covers:

  • The test
  • Discussion
  • Summary

The last test of the Crosman 100 was back in December, when I shot a remarkable 5 pellets into 0.145-inches at 10 meters. That engendered the question of whether it was just a lucky group or the rifle was really that accurate. I said at the end of that report that I would return and shoot 10 five-shot groups at 10 meters with the same pellet, so we could see whether that target was a fluke or representative. I waited until my right eye was corrected again, to give the test the best chance for success. So, today is the day! read more


Precharged pneumatics, regulators and power adjusters: Part 3

    • Power adjustment

    • Understand?
    • Transfer port control
    • Michael — this is for you
    • Stability
    • Finally — how practical is adjusting power?
    • Summary

    Today I will try to finish my answer to Michael about power adjusters on precharged pneumatics (PCP), which I have broadened to include air regulators. Please read Parts 1 and 2 to see what has gone before.

    Power adjustment

    Michael, there are several things an owner can do to adjust the power of his PCP. A longer barrel will often increase power, but that’s not immediately within the owner’s grasp. We are talking about adjusting power of a specific gun by means of things that are easy to do, without changing or modifying the rifle.

    Striker (hammer) blow

    Power can be adjusted easily by controlling the striker blow to the firing valve. A harder blow will force the valve open wider or for a slightly longer time. Either one of those or both of them means that more compressed air can flow out of the reservoir to power the pellet. As long as the pellet is inside the barrel, the more compressed air that gets behind it to push it, the faster it will go. read more

  • Hatsan USA
  • Hercules Bully

  • Sortie Tact
  • Air Venturi
  • A new IZH 61?
  • Multi-pump
  • One last thing!

Here we go! I go to these shows thinking that nothing can get me excited anymore, and that ends at the first booth, Today that happened before the show opened. AirForce Airguns has been keeping a secret for many weeks that they promised to reveal just before the doors opened.

AirForce Airguns

A few minutes before the doors opened, AirForce revealed that they are incorporating the Theoben Rapid line of PCPs into their lineup. Formerly known as Rapid Air Weapons (RAW), the Rapid lineup is on the cutting edge of pneumatic quality. The only drawback they have is the long wait time when an order is placed. AirForce will bring their manufacturing prowess to bear on shortening the lead time between ordering and shipping, while maintaining the high level of quality the brand has become known for. read more

  • Rebuilt

  • Trigger pull
  • Surprise!
  • Test 2
  • Magazine capacity
  • Feeding
  • Label
  • Summary

Today we look at the power of the Crosman 102 bolt-action repeater that we are testing. This test went in a different direction than I expected because of the rifle’s design. I will explain as I go.

The rifle

You know that I just finished the test of the Crosman 100, and I’m getting confused between that rifle and this one. I re-read Part 1 for this rifle to familiarize myself with its operation, and good thing that I did. I had forgotten one thing that turned out to have a huge influence on today’s test. But I’m getting ahead of myself. read more

  • Summary

Today is accuracy day for the Crosman 100 multi pump and I had to get out the trime! If you have been reading the blog for more than half a year, you know what that means. If not, you will.

The test

The test was at 10 meters indoors with the rifle resting on a sandbag rest. I shot 5-shot groups today because the 100 is a multi pump. I pumped 4 times for every shot. I said in the last report I was going to pump 5 times per shot, but after examining the velocity figures I felt 4 pumps were enough. Because I only shot 5-shot groups, I tried 4 different pellets, and when you see the results you’ll be glad that I did! Five shots are a fair indicator of accuracy. They are not as conclusive as 10 shots, but in a pinch they will do. read more

Merry Christmas, everybody!

Here’s a special Christmas present for several readers — the start of my report on Crosman’s 102 multi-pump repeater.

History

The .22 caliber 102 repeater is derived from the 101, which was originally just called the Crosman Pneumatic. The numbers came much later. The 102 was made from 1929 to 1950, at which time all model 100 variants were terminated.

Crosman 102 receiver detail
The receiver doesn’t give the model number.

The gun I’m testing for you is the one I bought at the Texas airgun show, but received earlier this month. This one has the hard-rubber “clickless” forearm that was only available on this model in 1938 and 1939, according to the Blue Book of Airguns. The rubber has hardened and cracked with age and any benefit from the softer compound was lost decades ago. read more

  • How much was it?

  • Test 2
  • Sig Match Ballistic Alloy pellet
  • H&N Baracuda Match

  • Loading is hard
  • Summary

How much was it?

Before I jump into today’s report, which is on the velocity of the Crosman 100, I want to make a comment on the price. I paid $150 for this one. It has just been refinished and the powerplant was overhauled — I think. Even if it wasn’t overhauled, it holds air for months (I’ll explain how I know that), so it’s the same thing.

Remember how rare I said these are? I see one for every hundred 101s (the .22 caliber version) at airgun shows. A nice 101 will run about $125-150, so I don’t think it’s too much to pay for the far rarer .177 version. Sure you will stumble into fantastic deals from time to time, but on any given day at a good airgun show, this is about what one of these will cost. They cost that much in the late 1990s, so the price isn’t being driven by inflation. read more
