Umarex Forge.

This report covers:

  • The test
  • Trigger
  • The test
  • Accuracy — JSB Exact RS
  • Accuracy— JSB Exact Heavy
  • Accuracy— Crosman Premier Light
  • What next?
  • Final group
  • Evaluation
  • Summary

Today I complete the report on the Forge from Umarex. This is a breakbarrel rifle with a gas spring and … Well, you can read the past posts to catch up.

I’m running this test because the last time we looked at the Forge I felt the poor 4X32 scope that was provided with it might not have extracted all the accuracy the rifle can produce. I vowed to return and test it with a better scope and today the Force is mounted with the Aeon 8-32 AO scope with trajectory reticle, which is one of the best scopes I own. You can read about it here.

The test

This will be 10 shots with each pellet from a rested rifle at 25 yards. I started with the conventional artillery hold but soon discovered the Forge can be rested directly on the sandbag. I used the artillery hold in the last test, so that may make a difference today. read more

The detent and how I open the gun

I’ll start today’s report by answering reader Siraniko’s questions from the last post. He asked me to show the locking detent and how I manage to open the gun for cocking. Here’s the detent.

Benjamin Trail detent
The chisel detent is long and narrow. It’s not under that much spring tension, so it opens easily, but the shallow angle of the slope ensures that it locks the beech securely.

That detent chisel face is long and shallow but the spring is not that strong. I can push it in with my finger. So the long shallow slope of the chisel on the detent is what’s keeping the breech locked so tight. read more

This report covers:

  • Price-Point PCP
  • Silencers
  • Lookalikes
  • More lookalikes
  • $100 PCP
  • More than just guns
  • Hand pumps
  • Compressors
  • Airgun technology
  • Big bores
  • There’s more

Today’s report came to me as I was planning to test the accuracy of the Umarex Legends Ace in the Hole revolver. I have so many tests waiting for my time, but today’s report had to come first.

Gentlemen — we are living in airgunning’s Golden Age. I know I have written that many times, but today I would like to reflect on all the good things that are happening in our world. Let me start with the Price-Point PCP.

Price-Point PCP

When I got into precharged pneumatics in 1995, I was dragged into it kicking and screaming. No PCP rifle cost less than $600 in that day (think $900 today) and the high-pressure hand pump had just been invented. I had to use a 3000 psi aluminum scuba tank that cost an additional $120 and I had to beg the local dive shop to fill it for me. I actually created a release form that I signed and left on file with them to absolve them from all risk of selling air to a non dive-certificated person! That might sound extreme in 2018, but in 1995 that was the way it was done, and plenty of dive shops refused to sell us air. read more

Beeman R9 with Vortek center-latching air piston: Part 2

Part 1

This report covers:

  • Today’s fill
  • JSB Exact
  • Predator Polymag
  • H&N Field Target Trophy
  • H&N Baracuda
  • Crosman Premiers
  • Benjamin Cylindricals
  • Cocking effort
  • Trigger pull
  • Firing behavior
  • Summary

Today is velocity day for the Beeman R9 with the Vortek center-latching gas piston that I’m calling the center latching unit (CLU). Bear in mind as you read today’s test, that this unit allows the owner to adjust the pressure inside the gas piston — raising or lowering the velocity and cocking effort. So, this is the first of several tests of the unit.

Today’s fill

I filled the CLU to 675 psi when I installed it. So that’s how it’s set up today. I will test it with 6 different .20 caliber pellets — one more than Pyramyd Air carries, if you don’t count the felt Beeman cleaning pellets. Let’s get started. read more

This report covers:

  • The big news
  • Benjamin Fortitude
  • Marauder Field and Target
  • Akura
  • Traveler
  • SigASP20
  • Tight breech and no droop
  • The trigger
  • AirForce E-Pump

I will start the third day on the SHOT Show floor with Crosman. They always have loads of new products and this year was no exception. I actually had to visit the booth two separate times to get what I am about to tell you.

The big news

So — what’s the big news at Crosman? I guess that depends on what interests you, but since I am defining this year’s show as the battle of the price-point PCPs (precharged pneumatic rifles with upscale features selling for under $300), let’s start with the Fortitude.

Benjamin Fortitude

Benjamin’s new Fortitude PCP is regulated, a repeater and has a shroud. It is positioned between the Discovery and the Marauder. read more

This report covers:

  • AirForce Airguns
  • What’s next?
  • Hatsan USA
  • Hercules Bully
  • Price point Hatsan
  • 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

They have the wrong twist rate!: Part 2

This report covers:

  • Been awhile
  • New airgunners
  • A better way
  • Doing what works
  • The point
  • Sharpening straight razors

Been awhile

Part 1 of this report was written way back in the beginning of February. I think the reason it’s taken me so long to get back to it is I titled it wrong. I will discuss that as we go, but first let me define who “they” are. In the words of comedian, Red Green, “They” are everybody who is not us. Now that that’s clear we can continue.

Part 1 was a treatise on twist rates and how they affect accuracy. As many of you are aware, I use this blog to school both new airgunners and also airgun manufacturers — who are often as ignorant of the facts as new airgunners, but cannot or will not admit it. No engineer who has just been hired by an airgun company is going to admit there is something he doesn’t know about guns! Heaven forbid! And neither is any CEO or owner of a company, because in their minds they are in a position of authority and should therefore know! read more
