I'm shooting a Contender pistol in a 6.5 X 50 bellm. using the same load, except for the bullets. One uses a 120g Nosler BT, the other uses a Remington 120g corelock. the problem is that the Nosler hits 4" lower than the Rem.? both shoot very well!!! at 200 yds. the difference is 8 -9". what is causeing this? :shock:
