Exclamation New ST-18 Design -- Brutus

Okay, here you go, Craig.

So much for 27 fps qualifying as "low Dv" (probably not, but I gave it my best shot).

I started out with a 9" long tube and a BC-1828, and kept adding nose weight (even an SE-14 and some WL-7 nose weights during the process), but that didn't really help things.

This basically ended up looking like a slightly more brutal Big Bertha variant, so I called him "Brutus."
