ORIGINAL: silverstreak
I took my White 50 cal Ultramag out and sighted it in today. I have it shooting 2" high at 100 yards. The load I am using is 90 grains of Triple 7 triple f and a 250 grain Barnes bullet. What surprised me is when I moved out to 200 yards the bullet dropped about 30", does that sound right?
