If you look in the textcensus, I just added several 4-digit gun periods that are multiples of 192 (7, 9, 13, 17, 19, 29, 31, 37, 43, and I might be missing one or two). Their bounding boxes are typically between 2000 and 4000 cells.

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).

[ElijahKen]

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.
[...]

Further reduction to 71*49 = 3479 by x25ing a Simkin glider gun:
[...]

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