Re: Pet .308 Loads
I used to run 175's at 2800 fps and found that they have a tendancy to be upset easily by head/tail winds so they get alittle unpredictable as you increase range. As I slowed them down they got less touchy but still exhibited that trait.
The 190's go where you put them and outperform the 155s easily without exhibiting any tendancies to be disrupted by head and tail winds. When you're calling shots to within a couple inches at distance those little things ad up for you or against you quickly.

Don't think of BC as the be all end all of shooting. It's a nice reference point for static comparision, but on target terminal performance should be your deciding factor.
The 190s for me @ 1100 ASL shoot 32 moa at 1000 yards, where as the 155's at 2950 shoot 28 moa.
In theory the 155 would be superior but with it's instability in slighty wind changes the 190 has the edge. It's a stable and predictable bullet.
