Blaine, 1/11 twist is still very versatile in 30 cal.
It was a head-scratcher for me when I discovered even my 1/12 twisted 308 can manage 208s at 2480 fps. Everyone pretty much assumed it wouldn't work. I had to see for myself. My results were sub-moa accuracy at 1120 yards from the ground with a bipod, and a Rem VS factory pipe. Who'da thunk it.
Wow!
Looked like this. Made a couple wind corrections, and then started ringing it consistently. 40 moa el correction from 100 yd zero.
