It looks better than what is currently in Chris's repository.
You have to be careful not to compare to the
p592 fixed gun, when the README.md says to look for a
p592 gun in the variable folder, with a bounding box of 5520 which beats 84x68=5712 by a couple hundred cells.
This is a minor difficulty with the new gun collection: nobody seems to want to go through and actually build the hundreds of new guns based on the variable-gun adjustments given in the README. It would be a great project for someone who really wants to get to know B3/S23 circuitry far too well...!
Anyway, the "fixed" guns are a complete set from p14 to p999, based on Dieter/Peter/Jason's old collection -- and they've (mostly?) been updated only if they get replaced by another fixed gun.

Ah, good, that's a 4602-cell bounding box, easily better than the previous best.
I wonder how many of the p8N+4s are improvable now, with a mixture of Snarks and p4 bumpers? Can just make a loop using simeks' timed reflector collection.
-- Hey, and what is a period 9N doing still in the Hall of Shame? I can reduce it a little bit with just a couple of modern period triplers, and I bet there's something better using Snarks and p9 bumpers.
