I've used the old 130g AB's in a 6.5X57 Styer, perhaps a tad over 2800fps, never recovered a bullet, but the deer went down with a good size wound. Close range longest perhaps 75 yards. Have a new CZ full stock in 6.5X55, seems 6.5mm bullets are hard to come by right now. Will try them and Hornady interlocks and perhaps some Bergers.
