I found Nosler necks were very thin. Too thin for use in my 270 AM (Necked down 300 RUMs)
Also found that case volume was a little less than REMs and heads/web area softer and body harder.
Blew primers with no extraction problems at all w/the Noslers?
Went back to REM brass.
If 280 I'd stick w/Win brass. Just better all the way around. (If they haven't changed it lately.
