The Gamo Pro Magnum Diabolo I have had the most consistent results, especially at distances from 10 meters. Goals were the usual cardboard targets, the duck box and a rat, of course, made of sheet metal. At shorter distances ranging the cheap flat heads, especially for "cans Shooting".
Also in the CO2 pistol Beretta 92 FS and the air gun Weihrauch HW 40 PCA Endorses the consistent quality of Gamo Pro Magnum pellets noticeable. In particular, the HW 40 PCA is sensitive to too large or too small pellets.
I have found here my standard diabolo. The price fits.
