This review is from Umarex CO² capsules, the company Umarex. These were in my case, in a transparent bag of 25 pieces, of the Fima "shoot-Club 24" shipping. Came one day after ordering, absolutely great!
Use the capsules in a Dan Wesson revolver 6 inches. The capsules are, as already mentioned, meticulously crafted and function properly. After the first capsules were used, came to subjectively feel that the capsules are filled to different extents.
The control on the scale then returned the following results to the fore:
4 cartridges were used up, 21 were treated with a jewelry scale (0.1g division) reweighed:
5x 11.1 to 11,4gramm CO² filling *
13x 11.5 to 11,9gramm CO² filling *
3x 12.0 to 14,1gramm CO² filling *
*) The quantities of cartridges, were determined on the basis of an unladen weight 28,7gramm. All unused capsules, had an identical curb weight!
This shows that in the cartridges generally less than 12gramm CO² contained. The price and the processing ansich, but leave nothing to be desired, something more CO² did the cartridges but certainly not bad. But that is clearly at Umarex or their manufacturers for capsules ...
Personally, I'm going, the capsules ordered here again. Let's see how the next deliveries are filled. The results I submit here after course.
Until then, Best regards from the Taunus.
