Original 45 info required

[stagmanv835]

Just having read an artical in novembers comic about the original 45 possed a question in my tiny mind

I acuired one in the late 80`s its in .22 with open target sights fitted

Its is also very easy to cock, i ahve necer chronoed so no idea of power i asume very low

question would this be a normal conversion for this rifle target sight and detune ? if so what sort of cometition would it be used for

would it take a lot to put it back up to full power spec for ratting with or should i hang it on the wall

There are members on here far better qualified than myself to give advice on the '45 so I bow to their better knowledge, but as far as I was aware- there wasnt any commercially available "target" version as such of this rifle. I wonder if a previous owner simply adapted a standard rifle for this use?

As far as power is concerned, the '45 is no slouch in this department. I have 2 of the RWS variants (same action juts a difference in the stocks) and have had both converted over to ptfe piston heads from leather and this has released further power and with an improvement in shot to shot consistency. I have then decreased spring input to lower ME but some would advocate packing the head out to reduce the lock time which in itself can bring accuracy benefits.

The '45 is a cracking rifle and as the mag article says a classic sporting air rifle- well worth keeping hold of and improving if you are able to.

The German Diana website still advertises the '45 so I think it may still be available to special order (though I am not 100% sure).

Good luck with the rifle.

I would suspect a new main spring (NOT an Ox ) a piston washer (new or refurbish the old) and a re lube should bring it back to full power. A session over the chrono would be advisable after the event.

p.s. If you look on the l/h side of the action you should see, in very small numbers, the month and year of manufacture. This may help when ordering spares.

If I remember right, there were a lot of rumours of grey imports of German air rifles in the 1980's. Germany actually had a lower power limit than we did, somewhere around 9ft/lbs I think, no idea how the power was reduced but it's one possibility.

Diopter rear sights were normally fitted to air rifles only for indoor paper target shooting, but then only in .177". I don't know of a paper target shooting discipline for .22".

However, people who shot .177" indoor paper target disciplines will have been used to shooting with diopter rear sights, and it's not unheard of for them to fit a diopter on their field or hunting air rifle. In any case, it's highly unlikely they'd go to the trouble of reducing the power.

I'd say chrono it and, if the power is acceptable, don't do anything to it. You may need to run 100 to 200 pellets through it to clear lubricants from the compression chamber and stop it dieselling before testing it if it's been unused for a long time.

I'd be very wary of fitting an uprated mainspring. The '45 was designed to exceed our legal limit (for the American market) and as jonnyone rightly points out, it's all too easy to inadvertently exceed the limit. When I had a dealer's ticket, I fitted PTFE heads to Original 45s and had to pack the heads to reduce the stroke to get the power within 12fpe.

Unless you know what you're doing, I'd suggest you consider seeing whether Sandwell Field Sports or V-Mach will tune the rifle for you.

6fpe for the home market, and the rifles were stamped (I think with the letter 'F' inside a pentagon). I personally have never known of a German market Original 45 being imported.

The Original 45 was built to beat the Hw35
The hw 80 was built to beat the 45.
The 48/52 ..built to beat the 80.
German power struggle/arms race.
Hw100 vs Rws 500...it still goes on...sort of.
Agree,no ox;s,supersport size titan ok,silicone oil leather washers.mind the power though.. they limit easily especially .22 .
better built than most of today's offerings,look what an icon it took to beat it.
