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).

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):

Also, I don't know how to update Catagolue, so if you could teach me or do it for me, that would be appreciated.

To get your glider gun reductions onto Catagolue, you can submit them into the box on https://catagolue.hatsya.com/syntheses (scroll down to the very bottom and insert your RLEs in the "Post New Syntheses" box).

The procedure for submitting a new or updated glider synthesis of anything is the same as well -- they are uploaded to Catagolue by the same process.
