Message from Pyramyd Air
Before I begin, here’s an email message that went out from Pyramyd Air to everyone who bought a Crosman NP2 rifle from their first shipment.

Subject:
Important Information Regarding Your Benjamin Trail NP2 Purchase

Message:
Thank you for your recent purchase of the Benjamin Trail Nitro Piston 2 airgun from Pyramyd Air (Part # PY-3368-6474). We have been notified by Crosman, the manufacturer of the Benjamin Trail NP2, that there were manufacturing process variances that may have affected some of the airguns in the initial shipment. We have determined that your order came from this shipment. While the variances appear to have impacted only a small number of guns and there are no safety issues, we would like to offer you the following options: read more

Shamal
Air Arms Shamal is an attractive PCP. It was Air Arms’ first precharged rifle.

This report covers:

• Accuracy at 25 yards
• Accuracy at 50 yards
• Pellets that didn’t work
• An observation
• Next time

We’ll begin looking at the accuracy of my .22-caliber Air Arms Shamal precharged pneumatic air rifle. We learned in Part 2 that this rifle wants to be filled to 2250 psi, rather than the 2600 psi that I remembered. Of course, the gauge on my carbon fiber tank is different than the gauge on the Shamal fill clamp that I no longer have, so some difference is to be expected. This is a good example of why a chronograph is so important when testing a PCP. If you don’t understand why I say that, read Part 2, where I used the chronograph to determine the optimum fill pressure. read more

Part 1

Shamal
Air Arms Shamal is an attractive PCP. It was Air Arms’ first precharged rifle.

This report covers:

• Trigger adjustments.
• Discovering the maximum fill pressure.
• Shot count.
• Velocity with various pellets.
• Discharge noise.
• Loading.

In this report, we’ll discover the Shamal’s pressure curve, which will be instructional for all who are new to precharged airguns. As I mentioned in the first report, this rifle didn’t come with a manual; so when I got it, I had to discover the pressure curve on my own. I did, and it turned out the rifle wanted an initial fill pressure of 2,600 psi. That was on the gauge that was on the fill device that came with the rifle — the device that I no longer have. I need to find out where on the gauge of my carbon fiber tank the needle wants to be when the rifle is full. These small pressure gauges are not that precise, so the number could be off by several hundred psi. Also, the gauge on my carbon fiber tank isn’t marked in hundreds of psi. There will need to be some interpolation involved. read more

Shamal
Air Arms Shamal is an attractive PCP. It was Air Arms’ first precharged rifle.

This report covers:

• The story of my Shamal.
• Description of the rifle.
• Performance.
• Trigger.
• Old versus new.

“Sadly, my Shamal went away. I know the man who owns it and he still treasures it to this day. If I still had it, I probably would not allow it to get away from me a second time. It was proof that you don’t always need a new air rifle to have a good one.”

Those were the last words I wrote about my Air Arms Shamal in the April 8, 2009, report I wrote on the old blog. I wrote that report for blog reader Kevin, who is still a reader and one of the most knowledgeable contributors to this blog. He asked what was the quietest .22 PCP I ever heard, and this rifle was my answer. read more
