Fellas, no 6.5 or 7 mm bullet's G1 BC equals what Sierra's 30 caliber 240-gr. HPMK has at .711
According to www.shootforum.com
bullet database, the JLK 7mm 180 gr VLD has a BC of .735, and the Lost River 7mm 160 gr J36 has a BC of .715. According to the same database, a 30-cal Powell River Labs 250 gr tungsten alloy BT has a BC of .84, and the 240 gr Sierra HPBT MK has a BC of .699. Regardless, when you get into heavy bullets, it starts to take a toll on the shooter in recoil. That is one advantage of the 6.5mm and 7mm bullets, they are lighter.
