Hi,
Just to add to the discussion a little more.
I did four ten shot strings over the Combro chronograph last night with two different types of pellets.
The first two strings with a 1/4 full air cylinder
Geco
480
487
483
482
493
483
489
488
480
486
R10
496
498
496
500
497
494
493
495
493
496
I then did this again with a full (200Bar) air cylinder fitted.
Geco
477
473
481
478
483
485
483
487

481
R10
495
490
487
493
491
490
494
492
492
489
As you can see the Geco's are very slightly slower through the pistol than the R10's are.
Both have the same stated tin weights. But I suspect the R10 is fractionally lighter and this gives the increase in FPS.
The test was done just as a matter of interest to see how the LP10E regulator performed with a full then nearly empty cylinder fitted. As you can see there is hardly any difference!
As I had the two pellet types I though it would be a good test of the variance.
The largest shot to shot change (Gecos) looks to be 11fps which is only 0.022% of the highest (493) velocity reading from that 10 shot string.
On the R10 the largest shot to shot change is 6fps which is only 0.0121% of the highest (495) velocity reading from that 10 shot string.
So yes the R10 looks to be more consistent, but the improvement is only 0.0099% of the velocity range.
You need a bigger sample size to give precise results, but this is enough to convince me that the quality is good enough on the low cost option.
Again with rifles on the far smaller target, this can add up to be way more important than it is with the 10m pistol.
Thanks
Mark
