How is she holding elevation?
The .223 has a reputation for not holding elevation very well at that distance, I guess it's a capacity issue. Do the larger .22 cases solve that?
224 Valkyrie shooting the red rocket. It’s all in the OP. 80gr ELD-M at 2855 FPS stays supersonic to about 1300yds, according to ballistic calculator. The shot marker said they were 1240-1270 at 1000yds.
