[QUOTE="bigsky, post: 150331, member: 7620"] I just got came back from the range yesterday and was suprised to see my BC I got using muzzle/100 yard velocities. My rifle is a Model 70 .270WSM with about 200 rounds through it. The bullet used is a Nosler Accubond 140 grain with a published BC of .496. While at the range I recorded muzzle velocity and 100 yard velocity with three round as follows. 1# 3250 and 2962 2# 3253 and 2962 3# 3275 and 2982 I used these velocities and came up with a .313 BC on JBM calculations. I was suprised at the large difference in the BC which will change my bullet drop about 22 inches at 700 yards. I called Nosler and they seemed suprised and stated that the bullet might be having a difficult time stabilizing out of the muzzle, causing the BC to drop. I am interested on your thoughts.
