I think that I found a boundary reduction to the
gun_3000.
My gun saves 253 cells, with an area of 4661 (59 x 79), reduced from 4914 (78 x 63).

It is also possible to add a semi-snark and double the period in the same bounding box. This also beats the
gun_6000 record.

Okay, thanks. Here is a probably not ideal period 9000 gun (but it does beat
gun_9000 by 1697 cells):
