Abandoning Regulators...

[Hsing-ee]

I can't remember where I saw it but someone mentioned that some shooters are abandoning their aftermarket regulators in favour of unregulated air supply. Something about it being simpler just to find the sweet spot and working within that rather than deal with the unreliability of regs.

It might have been on the BSA forum.

Is this a lot of nonsense?

Haven't seen it but I did once query why a buddy bottle gun like the R10 which has a history of regulator problems, should have a regulator at all.

The early Rapids didn't and they offered plenty of shots in the sweet spot.

My philosophy where pcps are concerned is keep it simple. Since I don't hunt, I don't need multishot, and I don't want a regulator to add another set of O rings and a greater risk of leaks.

So after returning to the Dark Side after 8 years of owning only springers, I've ordered a new version of that old favourite, much beloved by Tinbum , the AA S400 Classic in 177.

I know of many owners who prefer unregged guns. I have both but I only use my unregged gun when hunting

Ah yes, I think he loves them nearly as much as he does the HW35!

They should have gone to someone who knows what they are doing with regs. Cant fault mine.

quite simply, more o rings and more moving parts then the greater chance of a failure, none of my regged guns are more consistent or more accurate than my unregged gun

If you asked me whether a regulator was necessary if the rifle had a large air cylinder then I'd say no not necessary. Getting an after market regulator to work at its best requires quite a bit of adjustment to the innards of the gun. From the hammer to TP needs to be tweaked. So if the rifle can give you 80 shots along its sweet spot with a spread of 10~15 ft/s then the change in POI for a .177 is not that great to warrant a regulator. A gun with a small air cylinder is a different story.

Bartholomäus Girardoni's airgun was unregulated (in 1779). 2016 Steyrs are regulated.

I know what I'd prefer.

But that's only because I'd sell the Girardoni to buy a Steyr, plus enough cash left over for a spare house. In Mayfair.

So in reality - Nobody in their right mind would choose a knock-open valve if they could have a decent reg' instead.

I can see how BSA r-10 owners can become confused, because r-10 regs are crap.

That is what I think. Even if it doesn't make much difference in real-world performance, a 15 fps spread and having to arse around finding the sweet spot doesn't satisfy. Consistency is maybe not going to give shocking increases in accuracy but I don't like the IDEA of that much variation. Metered pulses of air is what we want ALL THE SAME one after the other.

what reg gives a "metered" pulse of air? all the regs I know about simply step down the pressure.

Only guns I know of that use the same amount of air at the same pressure are springers

The Reg on my R10 is working quite well.

Surely if the regulator is always giving the same pressure it is metered in a way. Wouldn't you need the same volume of air to achieve the same pressure every time. Or have I misunderstood how regulators work?

No, someone took the regulator off their R10 and swapped in Scorpion SE hammer and valve spring. The resulting shot string was very close to the original regulated shot string.

[GoodWILLHunting]

I have memories from years ago of shooting whole bottles worth of shots through my then new combro, to chart the pressure curve for the sweet spot.

Other than an fn12, all air guns I've bought since have been springers. Which even if left lying for a while they only require a dozen shots to loosen things up, left for an hour or so and then zeroed, if required. Ready to go.

If I ever buy another pcp it'll be regged.

You are correct. A regulator set at a certain pressure will keep the volume of air in the firing pot ( this volume is fixed according to the pot dimension ) at that pressure therefore so long as there is no dramatic temperature change the energy contained in that volume of air is closely matched from shot to shot.
A none regulated gun however, can not give the same energy to the pellet from shot to shot. The firing valve works against the pressure of the cylinder at all times, the firing spring force being constant and the air pressure gradually dropping from shot to shot . If by some mechanism the force of the spring could be altered to suit the pressure of the cylinder then the shots could be consistent ( Daystate MkIV, MCT,MVT , though these use a computer to achieve the goal ). AA Guns are very well designed for a none regulated gun but even here the gun has an acceptable shot to shot consistency between 160~120 bar. A badly designed or faulty regulator is worse than none IMHO.
