	Anyone know the "Ballistic Coefficient of hoch/darr 200 3 groove" .320 dia. bullet? Or the Saeco 200 grain flat nose in .320? The Saeco really shoots well but I'm worried that the wind is going to eat my cake over the darr bullet, what do you think? You sure can see the Saeco bullet holes better a 200 yards...... van

	Van- The BC of the 200 grain 3 groove 5r ogive B&D bullet is 0.324 (time of flight 444831 microseconds at 75 degrees F) measured over 200 yards with average muzzle velocity of 1481fs. An Oehler Model 43 Ballistics Lab was used with both muzzle and 200 yard chrongraph screens. While I do not have any actual ballistic data on the Saeco flat nose bullet, tests with a 200 grain B&D flat nose bullet of 200 grains yeilded a BC of .302 at 1475 fs. Regards, 7~
