## Execution of Old Guns by Variable-Speed Firing Squad

For discussion of specific patterns or specific families of patterns, both newly-discovered and well-known.

### Re: Execution of Old Guns by Variable-Speed Firing Squad

New variable gun family starting at p616, but it starts making improvements at p632:

The eater 3 shell can be replaced by a known but little-used catalyst to save another column:

Edit: and replacing an eater and eater 2 with a large sparker can save a row:

The eater 3 shell can be replaced by a known but little-used catalyst to save another column:

With that optimisation it looks like the p22-based p110 gun becomes smaller than the Herschel-based version. Area 2530 vs. 2550:

A p680+8N p4-bumper version of this improves p680, p688, and p696, and it looks like their period-halved variants too:

The mechanism for using a period X sparker to make a period 30X gun (where X and 30 are coprime) is interesting, and sees use in the p330 and p930. Are there any new p13 sparkers that could make a smaller p390 this way?

EDIT: Taking inspiration from that, a smaller fixed p506. I'm pleased that this actually worked and came out small.

Great trick! MWSS streams are easier to filter than glider streams. I was inspired to build this smaller p230 gun which relies on the ability of Bullet51's p10 sparker to delete two MWSSs instead of one:

Here also are reductions to the p460 and p920 guns, although they can perhaps be reduced further with a custom p4 sparker:

### Re: Execution of Old Guns by Variable-Speed Firing Squad

The gun collection only tracks guns with period below 1000.
I like making rules

### Re: Execution of Old Guns by Variable-Speed Firing Squad

I think that's everything from the recent wave. Thanks for the continued maintenance of the gun collection--looks like we're down to an average size of 4614 cells in the p78-p999 range. Further thanks to Sokwe, who continues knocking every new idea out of the park.

Some of the recent commits to the gun collection have a stray "k" or two at the bottom of the RLE--are these intended?

Anyway, some further rearranging of the p870, plus a replacement of the fumarole with a jam for style:

It uses Brice Due's old p92 gun (with a newer end cap). I found it simply by testing timing differences by hand to see if something magical happened. Magic was needed since there's not enough room for an eater to eat the extra MWSSs as in my earlier p1012 gun.

I almost skipped this reaction because I though it didn't work, but it looked fun so I decided to go back and watch it in slow motion. That's when I realized that it's exactly what I was hoping for.

I found this glider-releasing mechanism while looking for ways to trim a periodic syringe. It looks useful.

I replaced the pipsquirter with a small p6 to demonstrate that you don't need a particularly strong spark for this reaction (and for style). While this alternate p6 is typically worse than the pipsquirter, there might be some working sparker that is better.

Edit: It seems that BlinkerSpawn found this reduction half an hour before I did. I was also wrong in thinking a different p6 sparker could make the general glider-releasing syringe shorter. Unfortunately, the outgoing glider does not allow for the shorter eater 2 + tub with tail catalyst.

### Re: Execution of Old Guns by Variable-Speed Firing Squad

Thanks to both of you for showing the improvement, and that's a great demonstration of the necessary spark--the reaction might work down to p4 with a clever enough WLS result. p3 would be particularly useful, but that seems unlikely. Incidentally, where did that p6 come from? It looked like some sort of copy/paste error during experimentation at first.

Here's a p354, at a big 1544-cell improvement:

p3 won't work in any sort of reasonable way. A p9 variant can be made to work, but it might be too bulky to be useful:

### Re: Execution of Old Guns by Variable-Speed Firing Squad

Very nice pattern, It seems one can simply use to turn glider and change their phase in periodic constructions. There use to be 5 p4 glider turners, now there will be more (though a bit bulky).

I'm not particularly concerned about the p5; it's large, but it takes up what is often unused space in a bounding box. The p4 has a larger overhang.

EDIT: Unrelated, a smaller p972 by using a different base gun:
