Episode number 1, the very first use of a stargate shown, features two-way travel. Apophis appears, does battle, then leaves using the very same wormhole — there is no other plot option, since Earth has yet no dialing device. This is an inconsistency.

The “chilling effect” of early gate travel is later explained away as due to the SGC’s homebrew dialing device not applying any correction for galactic drift between the gates, as an Ancient DHD would. However, this explanation would not be consistent with the teams encountering chilling when returning to Earth.
