It uses an x10 multiplier that I found for a p41 gun, by placing a single block in front of the glider stream.
Slightly smaller (I am surprised this worked) (16128 -> 15792):
Code: Select all

Also, since gun_41 is different from guntrue_41, can gun_1189 be made smaller than guntrue_1189

Probably several others. The minor (in usage) syringe can be moved 1 fd to the bottom right as well (and also 1fd to the bottom left too, if I am remembering correctly). That template can probably reduce most of the largest guns on catagolue.

It uses an x10 multiplier that I found for a p41 gun, by placing a single block in front of the glider stream.
Slightly smaller (I am surprised this worked) (16128 -> 15792):

Also, since gun_41 is different from guntrue_41, can gun_1189 be made smaller than guntrue_1189

I also had the weird inspiration that we should have guns for all of the years CA have been investigated (so essentially guns from guntrue_1969 to guntrue_2025 should have representatives - missing periods 1975, 1976, 1977, 1981, 1982, 1984, 1985, 1989, 1990, 1991, 1996, 1998, 2001, 2004, & 2005)

What post? Also, was there a reduction the CP semi-cenark too?

It was an old post in this thread, I don't remember where. There was not a reduction to the CP semi-cenark, but this should work for many semi-cenarks in general. (Something else I found myself is that a traffic stop can also release a glider from the semi-cenark, but 1hd closer than in the CP semi-cenark. Same bottom edge as CP semi-cenark though.)

A reduction as well:

Something interesting to note is that the edgier syringe catalyst is the lowest population version with that eater nearby.

There apparently is a stable x13 multiplier of the form here (replaced with transparent blinker output for odd-period guns), found on guntrue_2028 in a less optimized form, which I reduced as shown below.

That guntrue_1840 exploded. Also those blocks in guntrue_525 aren't necessary. Lastly, just another reminder to link guns to catagolue like in the previous sentences.

The blocks in gun_525 were to mark the outer edges of the bounding box.

EDIt: gun_4350 should probs be this:

Not sure what you mean by p4230 (guntrue_4230 uses AK-94, and the sparker in this one is p29), but here is guntrue_4350 reduced with the tighter p5 sparker (the super small p5 is only useful if there is at least one more row in which the sparker can fit)
