Tune is slang for tuneup, and in airguns a tuneup can range from a quick lubrication all the way to a major overhaul of the powerplant and trigger. Everything in between these two extremes is also fair game. So, lesson one is that a tune can be anything that changes and hopefully improves the airgun’s performance.

I’m going to address a breakbarrel spring gun in today’s report. Other powerplants can also be tuned; but the steps are different, and the results will differ from what you get with a spring gun tune. Since the majority of airgun tunes are performed on springers, it’s appropriate to look at them first. And the breakbarrel is the No. 1 type of spring gun.

The HW 55CM target rifle: Part 4

Is this Custom Match the best HW 55 ever made? Read the report to find out.

In the last report, I tuned the rifle and got rid of the objectionable firing cycle. It’s always a great pleasure to return to a classic air rifle like this one after testing so many modern airguns, because these oldies are so reserved and well-behaved. I know it’s not going to kick, roar and fight me at every turn. It may only be suited to shoot 10-meter target, but sometimes — and by that I really mean often — that’s exactly what I need.

Sight-in
I had to remove the sights during the tuneup, so the rifle needed to be sighted-in again. It wasn’t that far off, but the indices are so dark on a 55 rear sight and my eyes are so bad that I had to play around until I discovered which way to adjust the sight to go right. In this respect, a modern 10-meter rifle has it all over a vintage one.

The HW 55CM target rifle: Part 3

Is this Custom Match the best HW 55 ever made? Read the report to find out.

Part 2
Part 1

This is a special Part 3 for the HW 55 Custom Match target rifle. It will be a retest of velocity, following a strip-down and lubrication with black tar to get rid of some uncomfortable vibration when the gun fires. When I tested it for velocity in Part 2, I discovered the rifle was shooting way too fast for an HW 55. Probably the Beeman Company replaced the mainspring when it went back to them for an overhaul. At any rate, when RWS Hobby pellets average 694 f.p.s., as they did for this rifle, you know something is wrong. I’ll try to remove as much of the harshness as I can with this tune, and I really don’t care how much velocity is lost.

The November podcast has been posted.

Before we begin, my buddy, Randy Mitchell, who was also the outlaw, Dakota, from Frontier Village (an amusement park in San Jose, California, from 1961-1980) sent me a photo from over 40 years ago. I was Casey Jones, the engineer who ran the railroad at the Village, and Dakota had put an obstruction across the tracks out in the badlands. When I stopped the train, he jumped me at gunpoint and forced me to clear the rails. Then, he stole my boots and drove the train back to the station himself. How time flies!

Tuning by Earl “Mac” McDonald

The saga of tuning the FWB 124 continues. While he was here, Mac replaced the Mongoose tune in my 124 with a fresh Maccari Old School kit, which consists of a Blizzard piston seal, a short mainspring and a spacer that slides inside the piston ahead of the mainspring. This he cheerfully did.

You may recall that my 124 was giving an average of 800 f.p.s. with the Mongoose kit. I felt that was too slow and wanted just a little more — perhaps 840 with Crosman Premier lites. The words on Maccari’s website seemed to indicate that the Old School tune was the ultimate way to go, so I ordered one.
