A history of airguns

This report covers:

  • The test
  • RWS Superdomes
  • Sig Match Ballistic Alloy
  • Firing behavior
  • RWS Meisterkugeln
  • Qiang Yuan Training pellets
  • Trigger
  • Summary

This is accuracy day! Today we will learn how accurate my new/old Chinese B3 underlever spring-piston air rifle is. This is the rifle with the replaced breech seal that we learned in Part 3 is such an easy fix. Today we see whether it matters.

The test

I shot at 10 meters off a sandbag rest. I used the classic artillery hold with the off hand next to the front of the triggerguard and rested on the sandbag.

I resolved to shoot just 5 shots, unless the pellet looked like it might group. If it did I would go to 10 shots.

RWS Superdomes

First up was the RWS Superdome. The first shot hit the target at the lower edge of the bull, but shot two hit above the 10-ring. I shot the next three shots and then looked at the group and decided this is not the right pellet for this rifle. The 5-shot group later measured 1.37-inches between centers. read more

  • Operation
  • Advantages
  • Evaluation

Today we look at the Umarex Strike Point multi-pump pistol. I overlooked this pistol at the SHOT Show this year, or if I did see it I got distracted soon after. Here is a brand new multi-pump that wants to play in the budget class. They are going up against the Crosman 1377 that is firmly entrenched. The Strike Point is several dollars less, so this will be an interesting launch.

I don’t think this will be resolved by the price. At this level both companies are almost giving them away. This will revolve around features and performance. I don’t want to compare the Strike Point to the 1377, but some things will obviously have to be said. read more

This report covers:

  • All tests
  • Does the POI shift with the reservoir pressure?
  • Fill the rifle
  • Bolt probe in the way
  • Second group
  • Second experiment
  • Experiment three
  • Bumped the barrel
  • Don’t bump!
  • Next

I told you I was going to test the heck out of the Umarex Gauntlet and I’m doing it! Today I’m shooting at 25 yards to test three things readers wanted to know about the rifle. Well, maybe I wanted to know them, too.

All tests

I’m shooting from 25 yards off a bench with a sandbag rest in front and a padded rest under the butt. The rifle is as still as I can hold it. All shooting is done single shot.

Does the POI shift with the reservoir pressure?

First I will test to see if a change in reservoir pressure changes the point of impact (POI). This is fairly common in PCPs, so we shouldn’t be surprised if it does shift. read more


Gamo’s Urban precharged air rifle: Part 2

Gamo Urban.

This report covers:

  • Fill probe
  • Pellets
  • Shot count
  • Air Arms Diabolo Field
  • H&N Baracuda Match with 5.51mm heads
  • Evaluation
  • Trigger pull
  • Summary

Today we look at the velocity of the .22 caliber Gamo Urban. And the first string will be an interesting test, because I know the Urban is a BSA design. BSA PCPs do not use their air the same as other precharged air rifles. The Urban fills to 232 bar, which is 3365 psi. Normally that would present a challenge to anyone wanting to use a hand pump, because pumping to that pressure level is difficult for most adults. But testing done by Tyler Patner (watch his video on the Urban webpage) confirmed what I suspected from the start — the BSA-based powerplant in the Urban doesn’t use the pressure above 3000 psi efficiently. It only becomes smooth when the pressure drops below 3,000 psi — the same as the BSA Hornet I used to own. Tyler found the best string of shots was between 2900 psi and 1500 psi. If I find the test rifle performs similarly I will constrain all my tests to that lower maximum pressure. It won’t make much difference at 25 yards, but it will at 50. read more

Today we begin our look at the Umarex-Legends-Ace-in-the-Hole-revolver. This Legends airgun is different from all others because it does not attempt to copy the firearm exactly. It takes the kind of license you would expect from a person who wanted to customize his sidearm. To appreciate today’s report we’re gonna need to know some history of the Colt single action.

History of the Colt Single Action Army (SAA) revolver

The SAA came into being in 1873, two years after the expiration of S&W’s patent on revolver cylinders that were bored though, front to back. Colt started by modifying their 1860 Army cap and ball revolver to become the Colt 1871/72 open top cartridge revolver, but in late 1872 they began producing what would become the most famous revolver of all time, the 1873 Single Action Army. read more

Today we find out how the makeshift faucet washer fix does fixing the B3 breech seal. Before I get on with the test, here’s a word about the piston seal.

The older B3s often have leather piston seals, but as the years passed the Chinese started putting synthetic piston seals in them. From what I have learned, you have to look at yours to be sure, because owners can replace the leather with synthetic.

Given a choice, I would choose leather, just because in a rifle of this power leather should last a long time, and as we know, the Chinese synthetics are not that reliable. I can’t see any advantage for power with either material. Now let’s test the gun and see what happened. read more


The Right Now pellet and BB trap

  • Time?

  • Future of the trap

I know that many of you readers are craftsmen, so today’s blog may disturb you a bit. You see, old BB is going to build something. I had a problem and found a very good (read that as cheap) way to solve it. I call it the Right Now pellet and BB trap.

One of the pastors at my church has a 9 year-old son who is very interested in guns. He’s a shy kid until he starts talking about guns. Then his eyes light up and he gets excited. I feel like I am looking at myself, threescore years ago.

I have been giving the boy my old gun magazines and he is soaking them up like a sponge. I also gave him a couple gun books that he and his father read together. His dad is not a gun guy, either, so I’m really working with two pupils here. read more
