Thread: Getting ES down with 223

@tikka, 16.5" 1:8 twist. That's seated 0.050" longer and 1 grain over ADI max.

Next I just need to modify a seating stem so it's not munting the bullets under such heavy compression. I think Belmont Magnum Pistol is the same powder as H110 so that would probably get the same kind of speeds without needing to be crunched down.

X+1.5gn of The special sauce I was trying is giving 2261 but it's scattering them all over the place and I doubt it'll tighten up before primers start popping.
