Will this thing stabalize at 900-100 FPS in a 1:10 ?
I kinda want a 200-220 grain cast bullet for use in my 308 at subsonic .
The answer is, yes. The graft is how it should preform in a 10 twist. A stability factor of 1.5 is stable and shouldn’t tip.
That said, it isn’t a very good shape for subsonic. The large meplate and trucated nose, give low BC’s, because the air has trouble following that shape. A rounded nose with a radi ogive, is much better for subsonic BC’s.
Spent yesterday contemplating what new and interesting things I wanted to try with the 30BR. This thread came to mind. Hope we are still on track for it!
