BSA tested this type of spring in the early 1900's. They were fited to BSA's up to WW2
Nothing new in airguning
Anyway, welcome to the BBS.

I was on Trobb's site and i clicked on the tuning section and came across a set of springs each half the size of a normal spring you combine them to become one spring. The beauty of them is that they are coiled one left and one right so that there is no twisting friction which is supposed to make the gun smoother and more powerful. Has anyone tested these ??

2 springs wound in opposite directions have also been used to good effect by feinwerkbau in their match rifles 300S/SU

hold me back !!
Wow fast reply and thanks for the welcome but do they offer any power gain??
Dident Relum do this in their Tornado???
I have 2 springs,one inside the other on my Relum Telly.

Would the springs need a very slippery joint between them to get any benefit??? Otherwise to my figuring, two opposing springs pressed against each other and released would generate a great amount of friction at the join and while not creating any clock/anticlockwise twist, would still cause some sort of jolt??

If they were such a good idea, all manufacturers would use them!
Well i was gonna breathe some new life into my webley vulcan i thought these would be a good idea but if theyre not what is the best spring over a standard one and why does everyone hate Ox springs
Go for a Titan XS. OX springs are harsh, nasty, vicious, gun breakers, that loosen your fillings. Unless you saw about a third off of them. Plus they're square sectioned wire, with razor sharp edges that can shave bits off the inside of yor gun. Titan however, are very good Swedish silicone steel.

In short, no. I think the idea was to remove the twisting effect of a single spring as it extends. The modern thinking, feel free to correct me if I've got this wrong, is to fit a top hat on the piston end and a decent delrin spring guide at the other end.
When the spring extends during the firing cycle the rearmost end breaks contact from the cylinder and so is free to "unwind" anyway, doing away with the need for double springs.
I used to have twin springs inside my HW97k silencer.
They where no good there as well.
