regulated or unregulated

[Timmytree]

why would a reged rifle need to be pressurised more?

The regulator is designed to make use of the higher air pressure that is wasted on an unregulated rifle. Fine if you have access to a big tank but not good if you're pumping.

thought the max was 180/190 anyway

I also thought a regulator just regulated the amount of air released or have i got it wrong?

Filling an unregged rifle a over 190 bar would result in the shots been low power,regged means you can over fill the cylinder and the reg gives each shot the same metered amount of air so giving more shots per fill,un regged guns have a self regulating valve and this works fine but in a window called the sweet spot,my s400 has a sweet spot between 165 and 120 bar where the fps spread is around 15

No, you're right but to get the higher shot count you need higher pressure. A well set up unregulated rifle uses the same air per shot as a regulated rifle but in a narrower range, hence the "sweet spot." If I regulated my S200 I may gain 20 shots per fill by being able to use the pressure from 190 bar to 155 bar or thereabouts. Since I only use the rifle for hunting and rarely take more than 10 shots in a session there isn't a need for a regulator. If I was target shooting and had a whacking great bottle at hand it may be different.
Even then, once your bottle drops below the optimum fill level you start to lose the benefit of a regulator.

On my huntsman I am filling to 225 and shooting 60 shots down to 140ish with no obvious poi shift at 30m. Much better than my un regged 410s and similar to my regged 410 I suppose

To get more shots my r10 i fill to 232 bar and i get 170 shots with a huma reg fitted . I wouldent like to hand pump mine .

That seems a very high use of air for a regulated rifle? Not much better than my S200 but with much higher pressures.

It isn't regulated

Here is my AA s510 .22 with a regulated 50 shot string never game close to this without reg.

My old (gone now) un-regged .22 s410 was tighter than those figures. I kid yopu not!
