Ballistics ,,fast and flat shooting even with different weight bullets,,
it's recommended that a person get the rifle of their choice with a barrel longer than 22 inches for velocity and also muzzle blast considerations.
115 grain Winchester Ballistic Silvertip deals a heavy blow out to around 200 yards.
It's a 30-06 necked down to a .257. Not 6.5mm. That would be the badass 6.5-06 that outta have more popularity than it does.
