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


Fred does some accuracy testing

by B.B. Pelletier

Before we start, I have a couple new things for you. First, February podcast is up. Yes, I said February! March’s podcast will go up shortly. Sorry February’s late, but we had technical glitches and some time issues.

Next, there’s a new article on Pyramyd Air’s website from one of my Airgun Revue magazines. It’s about Zimmerstutzens, which are in a class somewhere between airguns and firearms.

Blog reader Fred decided to see how his guns shot. So he took ’em all out and…well, that’s really the blog. I’ll let him tell it.

HW50S

Today is accuracy day, and the way I figure it, you guys are waiting for this report and the Beeman P3 accuracy report with about equal interest. The HW50S has delighted Mac, reminding him that great airguns are still being made. And, as Kevin pointed out days ago, the power of the new larger powerplant is approximately equal to the old Beeman R8, whose accuracy report I still have to do. So, if you lamented the passing of that great rifle, it’s still here by another name.

Mac mounted a Leapers Accushot 4-16x56AO SWAT scope. It has a 30mm tube and was mounted in Leapers Space Age 30mm high rings. The globe front sight and the rear sight were left in position and caused no problems with the scope. read more

HW50S

Before we begin, a medical update. I left the hospital last Friday with the blood clot in my shoulder seemingly not an issue anymore. The visit proved very beneficial because the gastroenterologists replaced the stent in my pancreas three weeks early, and an infectious disease doctor identified four strains of organisms growing in my pancreas that we are now treating with antibiotics. So, what felt like a setback turned out to be an advance.

I am weaker now as a result of the new medicines, but I expect that to pass. And I have the run of the house, which is where the bulk of my airgun testing is done. My buddy Mac continues to help me with the testing, so things should look pretty normal. read more

HW50S is a modern descendant of the fine Weihrauch line of spring-piston air rifles.

Mac’s first impression of the HW50S was of the Bavarian stock. If you aren’t aware of the style, a Bavarian butt comb slopes down toward the back, making cheek placement good for aperture sights but not for a scope. Mac finds the rifle well-suited to the open sights that come with it. He also mounted an HW55 target rear aperture sight on the rifle to see how it would work, and we’ll learn the results of that during accuracy testing.

Blog reader Vince tells us this new 50S isn’t the same rifle it was 20 years ago. That older rifle was related closely to the HW55 and has a 25mm piston, while the new model that Mac is testing has a 26mm bore. read more
