Hi.I'm Brazilian, so forgive my English errors (blame google translate). I'll try to help with some info.Here in Brazil these air guns are sold as "CBC Nitro X1300". They use 4,5mm (.177) pellets. We have in the same line the "CBC Nitro X1000" (5,5 mm/.22 pellets) and "CBC Nitro Six" (6mm Pellets). If you want to search in Brazilian forums, these are the same guns, just with different names.I've found a chrony test in a Brazilian forum for the "X1300" (in meters per second, sorry. We do not use measures in fps here.): with Gamo Pro Magnum pellet, 368 m/s (average after 5 shots).With Gamo Raptor pellet, 452 m/s (average after 5 shots).As you can see it's very strong for a air gun, but i think that Magthech X1300 is not the best choice if you want to use it in competitions like Field Target or Bench Rest, for example. Can be a good choice for hunting, or in use just for fun.(Hope I did not made many mistakes writing...)
