I've had good luck and results with starline in a 270 Win. Brass seems to be fairly uniform and has held up with some pretty stout loads of H4831 and 140 accubonds.
I guess I assumed that at one time or another the other three would have made a run. I've never owned a 270 but thought it was popular enough to justify a run or two.
Learned something new today. Thanks everyone for the response and info.
