KA M4 velocity after break-in period

Hey all,

Quick question, I recently bought my first replica, a brand new King Arms colt M4.

At the store it was shooting 405 fps with .2s right out of the box, they assured me it would drop after a while.

So far I haven't had many chances to use it so it has maybe 1000 rounds though it, and I couldn't use it at our last game as it was still shooting hot, averaging 402 fps, spiking at 406.

Question is, what's the best way to break it in and will it actually drop enough to game with it, 390 fps would be perfect, but I don't know if that's realistic.

I want this gun for outdoor use only, no cbq, I don't really want to get the spring changed unless it's necessary.

thanks
