Most of the drivel decrying the 270 is Internet chatter,hawked by a small but highly vocal minority.
They remind me of the same crew who, back in the 70's, preached that elk should never be hunted with anything less than a 338 with 250 gr. bullets. Geezus those guys got boring after awhile...the reason I just stopped reading Elmer.
The 270 probably packs more meat in freezers and puts more big heads on the wall every year, than all the wonder cartridges combined...except maybe the 30/06.
