Ever since I started using 79rd G&G midcaps (brand new), the first 3-4 shots of the mag result in lobs that go about 8 feet out and occasional double-shots. After the first couple shots, everything is completely fine and accurate until I switch to a new mag. It's only the first few shots of a new mag.
Am I overloading the mag itself, giving too much tension to the spring? I checked the hopup, air nozzle, etc. and everything seems to be in working order with nothing broken. Any ideas?
