1:9 heavy subsonic .223 Qs
What is the heaviest bullet you have been able to stabilize in a 1:9 loaded to about 1k fps? If you are comfortable sharing the load data, please do so. I am curious to see as I had intended to build a fast twist Hornet for such applications, but was told it would be easier to do with a .223 due to brass life and availability. The heaviest/longest I have is 55 Vmax, but wonder if the 60 Vmax, or any of the 68/69 grainers would stabilize at subsonic speeds in my 22" 1:9.

So in a standard bullet, would the distance be from the base to the ogive and in a boat tail bullet from the end of the boat tail taper to the ogive? Neither the boat tail nor ogive engage with the rifling.
