The .308 is short action and available appropriately twisted. The case is OK but not great. The .270 is one of the worst designed hunting rounds of the 20th century - wrong twist, crap bullets as a result, too much taper, too steep a shoulder. It really gets nothing at all right. A junk round that reflects poorly on those who shoot it.
Sounds like someone who tucks his weiner under and dances around in front of the mirror...just saying...
