[QUOTE="WiscGunner, post: 2613881, member: 97288"] You are of course welcome to your opinion but like other have said, I am not in your camp of thinking. BC certainly does matter long before transonic velocities. BC help extended the range if minimum expansion. The ability to judge wind to 1mph is highly unrealistic but having a high BC bullet that gives you far more room for error in your wind call is definitely realistic and many of us that shoot/hunt long range utilize high BC for exactly this. But then perhaps your definition of long range is different than others? Max range of expansion with Factory estimated BC .259G7 [ATTACH type="full" alt="58517968-FC1F-4458-804F-AAD3941622E7.jpeg"]392561[/ATTACH] Max Range with actual field use .206G7 BC [ATTACH type="full" alt="B90CF948-7DD7-41FF-B236-F9CC7F99E27A.jpeg"]392562[/ATTACH] Hornady 180gr ELD-M [ATTACH type="full" alt="E1BD869A-D20C-4836-A203-B9EAE262D78D.jpeg"]392563[/ATTACH] I love the Hammer Hunters in my 7SS but clearly they are a 600yrd bullet for me. Others might take them further by pushing harder for more velocity but I prefer better barrel life and temp stable powders so I use H4350 for the 155HH and H1000 for the 180 ELD-M. Eliminating range/velocity errors is in the same league as reducing wind call error with higher BC bullets. Better components help me meet my goals for accuracy and quick killing. Knowing the limitations of your gear is important. Note the 180 ELD-M is approx 200fps slower but way better wi dow for error in wind and retained terminal velocity. [/QUOTE]
