I know, we've soon tons of messages titled like this... The 6.5-284 is kind of popular right now with accuracy-plenty and a good long-range record up to and beyond 1000 yards... It has also been described as having a barrel-life (accuracy life) of probably less than 1500 rounds... The good-old 270 win on paper seems to have similar powder-charges, ballistics (maybe even faster with a 140 grain), and even ballistic co-efficients (berger VLD 150 looks nice). I wonder why as a long-range hunting caliber, the good, old 270 isn't more popular. Also wonder if it is plagued with the 1500 rounds or less barrel-life or is the longer-skinnier powder-column somehow more protective of the barrel throat ?? Wondering because now that I sold my 270 win (Rem) and bought a nice Savage 308 (P/TR), maybe in a year or so I'll get a 270 win barrel for the Savage !!
