Diana 72
Diana 72 is a youth target rifle from the late 20th century.

This report addresses:

• More on the trigger.
• Accuracy with various pellets.
• Why 5 shots?
• Accuracy with deep-seated pellets.
• Summary.

Today is accuracy day for the Diana model 72 target rifle. We had one extra report in this series, and that was on adjusting the trigger. I want to tell you some more of what I have learned about this trigger.

More on the trigger
During the accuracy test, the trigger failed to work two times. The first time I made a small adjustment and got it running again in a matter of a minute. The second time, however, I worked on it for 15 minutes without success. I finally read Part 3 of this report, to see where the two adjustment screws had been positioned when the trigger was working. The camera angle of that photo isn’t the best, so there was still some guesswork involved; but even then I couldn’t get the rifle to fire.

Today, we’ll test the Walther 1250 Dominator at 50 yards. I had to go out to the rifle range for this test, and we’ve been having some winds lately, so it took some time before I got a calm day. But this day was perfectly calm — I couldn’t have asked for a better day to shoot an air rifle at long range.

As you recall, the Dominator takes a 300-bar fill, which is 4,350 psi. I had to delay the test to get my carbon fiber tank refilled, and even then I didn’t have enough air for a full fill. When you fill a tank, it gets warm; and when it cools back down, you lose several hundred psi. I was able to fill to about 4,100 psi this time, but that single fill was enough air to last for the entire test, which was about 50 shots. And the needle in the pressure gauge is still in the green, which means there are more full-power shots remaining in the rifle.

Let’s look at the Walther 1250 Dominator accuracy at 25 yards. In deference to the 8-shot clip, I’m shooting 8-shot groups rather than 10. The way this rifle loads, with the clip almost disappearing in the receiver, it’s too difficult to keep track of those 2 extra shots.

It’s loud!
I’ll be honest — I stalled testing this gun in the house because of the noise. It’s one of the loudest airguns I’ve ever shot indoors.

Air use
I said last time that I would give you a shot count once I filled the rifle to 4,350 psi (300 bar). Well, that didn’t happen. I filled it as far as my freshly filled carbon fiber tank would go, but that was only to 4,200 psi on the tank’s gauge, which seems pretty accurate. The rifle’s gauge showed a lower fill pressure, but I chalk that up to small pressure gauges never agreeing.

Thank you for being so patient with me on this Walther 1250 Dominator report. I had to suspend it while I was back in Maryland; but now that I’m home, I can start up again. Today is velocity/power day, so we’ll learn a lot about this air rifle.

Filling with air
To fill the reservoir, you first remove it from the rifle by unscrewing. Then, it’s screwed onto a brass adapter that’s screwed into a 300-bar DIN hole on a carbon fiber tank or scuba tank valve.

You fill the reservoir up to 300 bar, or 4,351 psi. The only way to get that much pressure is to use either a carbon fiber tank or to connect the reservoir directly to an air compressor or hand pump that goes that high. My carbon fiber tank was holding less than 3,000 psi when I conducted this test, but fortunately the rifle has a broad power band. Even though I can’t fill the reservoir all the way, the gauge on the tank still reads in the green. I’ll get fewer shots, but they will be at the same velocity. It’s just like a car that goes no faster when its gas tank is full or nearly empty.

It’s accuracy day for the IZH 60 Target Pro and this is the big test that everyone has been waiting for. And there are a couple of things that have to be cleared up, too. So let’s get started.

Cosmoline in the bore
Blog reader chasblock mentioned finding Cosmoline in the bore of his rifle and asked if I would take a look at the test gun’s bore. I don’t think he really meant Cosmoline, which is a range of military long-term metal storage lubricants. He probably just meant excess grease or oil. At any rate, I ran a patch through the bore, and it came out dry. There was some anti-oxidant compound on it, but no oil or grease. So, that’s one down.

Today is velocity day for the IZH 60 Target Pro. Before we begin, there’s a surprise correction I need to make to Part 1. When I measured the length of pull, I didn’t mention that the adjustable stock can be lengthened an additional inch by relocating the anchor point of the adjustment screw.

Increased length of pull
Mac reads the blog sometimes, but he doesn’t comment very often but he loves the IZH 60/61 family of rifles. After reading Part 1, he called and reminded me of something I’d forgotten. If you pull the butt stock off its post, you’ll see a second spot for the screw anchor on the butt stock post. All you have to do is move the anchor from the first slot to the second, and you’ll add just over an inch to the length of pull on your rifle. I had reported a LOP range of 12 inches to 13.25 inches in Part 1. Now, I’ll revise that to a maximum of 14.5 inches. (Edith will amend the owner’s manual to show this info.)

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.
