been trying different ammo in 30-06 to take on my first elk hunt in october the three best consistant 100 yard groups are 2 1/2" from federal nosler 180, 1 1/4" from win. superX 180 SILVERTIPS,and 3/4" from hornady light magnum 180 btsp interlocked. I know the nosler does good on elk but the other two group better have any of you guys used these on elk?
