In review, we can see that in .177 caliber, the Stoeger ATACs tested are shooting around 880fps with 8.64 grain Stoeger X-Field pellets. That's just under 15 ft/lbs of muzzle energy. Standard Deviation is very well controlled for a new gun at less than 8 fps for the 10 shots.
The .22 caliber guns tested give a muzzle velocity in the 715 - 750fps range with Stoeger X-Field (14.66 grain) pellets. Muzzle energy is in the 16.5 - 18 ft/lbs range. Again Standard Deviation is good at between 4.5 and 12 fps for 10 shots.
Note that the trigger pull weight varies around 5 - 6lbs with the factory trigger This is normal for all Stoeger Airguns. The GTX Generation-II trigger (which is specified by most of our customers for these guns) gives a much better pull weight of 3 lbs or less, as you can see in three of the test targets, together with improved feel and shorter length of pull. The GTX is a great improvement for practical shooting of these air rifles!
In summary, performance of the new ATAC is very much as anticipated. The guns are quiet: very similar to the noise level of the Stoeger X20 Suppressor.
Paul, who shot these targets, feels that accuracy is excellent - at or above our normal tested results for Stoeger Airguns. He and I both find the ATAC comfortable to shoot and like the 4 - 16 x 40AO scope.
This is an excellent new air rifle.
