How spring-piston rifles behave

by B.B. Pelletier

Okay, Grasshopper, enough Wax on! Wax off! It’s time to use your skills.

If you’ve been following the discussions over the past month about accuracy, you should now have the tools to be a pretty good judge of the potential accuracy of an air rifle and the relative ease with which that accuracy comes — even before taking the first shot. We’ll confine today’s discussion to just spring-piston guns, since they’re the most difficult to shoot.

How a spring-piston airgun works
This is a review for many of you, but we have enough new readers that perhaps it’s good to go over the points of how the spring-piston gun works. What I’m about to say holds true for guns with gas springs as well as guns with coiled steel mainsprings. They all work the same when it comes to their operation. read more

RWS Diana 350 Feuerkraft in .177: Part 1

The RWS Diana 350 Feuerkraft is a budget version of the 350 Magnum powerplant. It still comes with open sights, so nothing more to buy.

This test has been requested many times and for over a year. I reported on the RWS Diana 350 Magnum in .22 caliber way back in February 2006. Although that report was an early one with only one short part, the real objection has been that I tested the .22 caliber rifle. Those making the request for a retest wanted me to test the .177.

For rifles in the 350 Magnum’s power class, I feel that .177 is a waste of energy. They shoot the lightweight pellets too fast for accuracy and they waste a lot of potential power because the .177 bore is too small to transmit the energy. But, people kept right on asking; and when you wore me down, I finally saw the light. So, here’s the test you’ve asked for. read more
