I just got a new Beeman GT600 in .177 as a gift for Christmas. Seems like a great gun, very accurate and seems to shoot very hard. The trouble is, I know nothing about airgun shooting. Does anyone know the velocity of pellets shot out of this model? Also, I'd like to hear from some of you air gun pros out there.... any tips on interesting targets for backyard shooting? Or tips on airgun shooting in general would be great. Thanks
