The Dragon Claw from Sam Yang is a .50-caliber big bore air rifle.

This is the second accuracy test with Sam Yang’s Big Bore .50-caliber Dragon Claw single-shot air rifle. As you may recall, or you can check out by reading Part 3 again, the rifle shot all over the place last time. I decided that I was not seating the bullets into the rifling as far as they needed to be, so this time I took special pains to seat all the bullets. I’ll tell you how that went as I report my findings.

Air use
I’m still filling the rifle from the same Air Venturi 88-cubic foot carbon fiber tank that I was using when I started this report. The tank has not been refilled, and there are now about 150 shots on the Dragon Claw (at the very least!), as well as a couple fillings for a Talon SS reservoir. The gun is still being filled to 3,000 psi, so that carbon fiber tank is definitely the way to go. read more

Today, we’ll look at the accuracy of Sam Yang’s Big Bore .50-caliber Dragon Claw single-shot air rifle. Thanks for being so patient on this report. It took three separate trips to the range to collect the data for what I’ll tell you today, and the report will not end here. This rifle has some more secrets to reveal, although I now know a lot more about it than when I started.

Break-in helps
For starters, this airgun needs some break-in time, so plan on it. When I started this test, the rifle was very stiff and hard to cock, but now it has smoothed up considerably. The hammer spring is still very stout, so cocking the rifle isn’t that easy; but at least the hammer comes back smoothly now. In the beginning, it was actually difficult to stop the cocking mechanism at low power because the hammer required such a yank to retract. Well, that’s behind us now; and the rifle can easily be cocked for low power or high power. Plan on about a hundred shots for a break-in. read more

The Dragon Claw from Sam Yang is a .50 caliber big bore air rifle.

Today, I’ll test the velocity of the Sam Yang Big Bore .50 caliber Dragon Claw single-shot air rifle. For this test, I used two Air Venturi bullets and a swaged round ball that are available from Pyramyd Air.

The rifle is supplied with a probe-type quick-disconnect fill device, and I can finally report that the Koreans have now conformed with the rest of the world in supplying these adapters with standard threads that attach to common 1/8″ BSP fittings. In the past it was a chore matching these adapters to hoses you might have on hand (if you’re already into PCP airguns). read more
