WARNING: This conversion changes the operation of the pistol to use air at up to three times the pressure it was designed for. The parts that are installed are strong, but there are other parts in the gun that aren’t changed and could fail when subjected to the higher pressures. Pyramyd Air advises anyone making such a conversion to exercise extreme caution.

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

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:

Air Arms Shamal: Part 3

by Tom Gaylord, a.k.a. B.B. Pelletier

Part 1
Part 2

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.

BSA Scorpion 1200 SE PCP air rifle: Part 3

We’re back to the BSA Scorpion 1200 SE. When we last tested it, we looked at the velocity and discovered this is a 30 foot-pound air rifle. So, its primary purpose is hunting. I thought that meant I should test some heavy .22-caliber pellets, but I also included a middleweight.

This test was done at 50 yards. I never shot the Scorpion indoors at 25 yards because it’s so loud. I went straight from mounting a scope to shooting at 50 yards. As it turned out, that cost me several more shots than normal to get on paper.

I scoped the rifle with the UTG 6-24X56 AP scope with illuminated reticle.

We’re back to the BSA Scorpion 1200 SE. My hand has finally healed, and I can now work the Hill hand pump, but I stopped part of the way through the first fill and made the necessary changes to the carbon fiber tank hose, to attach BSA’s proprietary fill probe. I gave up because I just got tired of pumping! Those who encouraged me to do this from the beginning have won me over, I guess.

This PCP rifle takes a fill to 232 bar, which is 3,365 psi. We’ve looked at fill pressures for pneumatics a lot over the past month, and today we’ll see what this BSA rifle manages to do with its fill. The advertised number of shots is 25 per fill.
