I got these to site in perfect with my diana trailscout and they work really good for small pests for sure but only with in 13 yards anything to much past that and they wont work to well ,, should be fine tho for birds at longer ranges but not sure on that one...

i gave these a 3 star for the gun i used which is the Stoeger A30 .177 cal the speed is great in the gun but the accuracy in my gun is not going to dial in just right how ever i will be testing on my other rifles in shich case ill update my review at that time. the cost is good for the amount of pellets and they are very well made as well so there are many good points but these just did not offer a tight enough group for dialing in ,, here is a link to my youtube video on the test which others were also tested but for these youll see your self now might you tho they wont work great in my a30 does in no means say they wont work in another a30 as no 2 guns are alike https://www.youtube.com/watch?v=Z8kZWRQUXSI
