a 21" 270 in a bodacious pushfeed does sound more nimble and handy than a 24" 6.5x284 at reasonable hunting ranges. I was handling a 22" M700 in the LGS today and wondering what I was thinking when I went with the 24" tube of my 280 CDL... and then remembered I wanted to maximize the V of the 280 to give it that little bit extra over a standard 270
