There's an automatic Team Fortress 2/Day of Defeat: Source Update that has fixes for the Orange Box Engine and Team Fortress 2 that also adds the following changes to the bullet spread algorithm (BSA) in the teamplay shooter:

    • Bullet spread algorithm changed to fire a bullet right down the crosshair under these circumstances:

        • The first bullet of a spread weapon (except for rapid fire spread weapons like the minigun)

        • The first bullet of a non-spread weapon if it's been >1.25 seconds since firing
