kiwiwildcatQuestion on bullet BC and length.
Hi guys,
Is it true to assume that given a 7 mm and 30 cal projectile of a similar BC that there respective lengths will also be similar?
Case in point: A 7mm 162gr Hornady SST has a BC of .550 and a .30 cal 185gr Berger hunting VLD has a BC of .549.
Cheers,
Michael.

ramrod340Your Hornady is 1.4" the Berger is 1.378" which are darn close. However for example the Barnes 7mm 168 has a BC of .55 but it is 1.592"

INTJIIRC, bullet weight is also a factor in BC.
