RWS Diana 45 air rifle
Diana 45 is a large breakbarrel spring rifle.

This report covers:

  • RWS Superdome pellets
  • Uh-oh!
  • RWS Hobby pellets
  • Air Arms Falcon pellets
  • Time to stop and think
  • H&N Baracuda Match pellets with 4.53mm head
  • Where we are

Today, we’ll look at the performance of the Diana 45 that we tuned recently. Although a new mainspring was installed, it has the same power as the spring that was in the rifle, so no vast power increase was anticipated. If there’s any increase at all, it will probably come from the new breech seal I installed. The old one was flat and hard, so the breech is probably sealing air better now.

The point of this tune was to eliminate as much vibration as we could. The rifle’s owner, Johnny Hill, did not like the buzz that came with every shot, and I told him that most or even all of that could be eliminated by tightening the tolerances inside the powerplant. At my request, he made a larger spring guide, and he buttoned the piston to take out as much vibration as possible.

BSA Supersport SE air rifle BSA Supersport SE

This report covers:

• RWS Superdome pellets
• JSB Exact RS pellets
• 8-32X Aeon Classic rifle scope
• Baracuda Match pellets, 5.53mm heads
• Different hold
• Evaluation of the rifle

Today, I’m shooting the .22-caliber BSA Supersport SE at 25 yards. I’m also testing the Aeon 8-32X50 Classic rifle scope with a trajectory reticle mounted in the Diana Bullseye recoil-reducing scope mount. Those 2 products will each get their own separate reports because today I’m concentrating on just the rifle.

In Part 3, I shot the rifle at 10 meters using the open sights that came with it. From that test, I selected a couple pellets to try today. But first, I want to show you a picture of the Aeon 8-32X50 scope mounted on the rifle, because in the last report I mentioned how short it is for this range of power.

Diana 45 is a large breakbarrel spring rifle.

This report covers:

• Barrel must go on
• Piston into the tube
• Piston liner and cocking shoe go in
• Install the barrel
• Install the trigger
• Install the barreled action in the stock
• Quick function test

Barrel must go on
I’ll pick up where I left off in the last report. To assemble the parts, the barrel has to go on the spring tube. During disassembly, I’d noticed during that the breech seal was flattened and hard, so it was replaced before anything else was done. It’s just an o-ring with a steel spacer underneath, so the old one was pried out and a new one was pressed into the groove.

RWS Diana 45 air rifleDiana 45 is a large breakbarrel spring rifle.

This report covers:

• Piston head swaged
• Eliminate sloppy tolerances
• Buttons
• Tighter spring guide
• Remove all burrs
• Clean the spring tube
• Lube the spring tube
• Lube the piston, piston liner and mainspring
• Lube the leather piston seal
• Leave the trigger alone

Today, I’ll show you all the things that have been done to the Diana 45 parts; and I’ll clean, lubricate and assemble the rifle. This will be a long report, so I am breaking it into two parts — today and tomorrow.

Piston head swaged
Before we get to the job though, I was asked by one reader to show how the piston head is attached to the piston body. If you want to replace the leather piston seal, the piston head has to be removed – and that isn’t going to be easy, because it is mechanically swaged onto the piston body.

Daisy 1894 Western Carbine: Part 3

Daisy 1894
Daisy’s 1894 Western Carbine is a classic BB gun. This one is an NRA Centennial model.

This report covers:

• Daisy Premium BBs
• Hornady Black Diamond BBs
• Avanti Precision Ground Shot
• Crosman Copperhead BBs
• Conclusions

Today, we’ll see if the Daisy 1894 can shoot. I know that a lot of you have been waiting for this report for a long time. I haven’t been waiting nearly as long as some of you, but I am just as excited. As I’ve said more than once while testing this BB gun, I like the way this 1894 feels when I hold it!

I shot the gun at 5 meters (16 feet, 4 inches) from a UTG Monopod rest. I loaded only one type of BB at a time, so the BBs didn’t mix. I shot at larger bulls this time, because the Daisy has open sights that aren’t too fine.

Daisy 1894
Daisy’s 1894 Western Carbine is a classic BB gun. This one is an NRA Centennial model.

This report covers:

• Preparation for firing
• Daisy Premium Grade BBs
• Crosman Copperhead BBs
• Hornady Black Diamond BBs
• Trigger-pull
• How is the gun?

Let’s look at the velocity of my Daisy model 1894 BB gun. Several of you said you were glad to see this report, and I’m happy to do it for you. The 1894 is a BB gun I simply overlooked when it was available. All of you knew how nice it was, but until now I never had a clue.

Daisy advertised the 1894 as a 300 f.p.s. BB gun. That’s not too hot, but also not on the bottom. It’s a nice place to be if accuracy is all you’re concerned with, because 300 f.p.s. is enough to do everything you need.

Diana 45
Diana 45 is a large breakbarrel spring rifle.

This report covers:

• Remove the barrel
• Barrel off!
• Remove the piston
• Disassembly is complete
• One last look

We have a lot to cover today, so let’s get right to it. We left the Diana 45 with the mainspring out of the gun at the end of yesterday’s report. The only thing left in the disassembly is to remove the piston. Do not disassemble a gun if you’re not 100% certain you can put it back together again in safe working condition!

Remove the barrel
The piston will not come out of the gun until the cocking link that connects it to the underside of the barrel (for cocking) is removed. To do that, you must first separate the barrel from the spring tube. That step is easy on some breakbarrels, but not so easy with this 45. On most breakbarrels, you remove the pivot bolt from the action forks and the barrel separates from the spring tube. The Diana 45 has another step; and unless you follow it, the barrel will never come off the gun.
