I have resized a lot of 30-06, 270, and 280 for my 25-06. 270 seems to be the easiest for resizing but takes a lot of trimming after. 30-06 the neck looks a little funny after resizing but after 1 shot it fire forms them perfect.
I agree with Bowlseye,if you shoot other calibers make 100% sure you know what you're grabbing.
