I usually shoot BH175gr and I know they have a .505 BC.
Is there a higher BC round in the 175gr range for reloading?

Re: High BC bullets
I went to the 185 Berger VLD... I can't reacall what the BC is off hand (I'm at work), but I know it's good, and does great in my Savage.

And the huge increase in speed bucks the wind alot better, and has less recoil.

And travels another 175 yards before entering the transonic vlocity range.

JRose,
the 185 vld bc's are .549 G1 and .281 G7 </div></div>
The box said .556, but I know they recently revised that. Thanks for the info.
As for bucking the wind, I dunno b/c I've never shot 155's, but the heavies seem to do pretty well bucking the wind for me. I suspect b/c of the high BC.

Re: High BC bullets
The Berger Long Range Boat Tail has the highest BC for 175 gr. bullets that I know of. Although, I've never seen results for JLK's bullet. Sure it's nowhere near what they have listed though.

You gain in drop and wind with them over the 175 SMK due to increased velocity. Both of their BCs are lower than the 175 SMK's.
None of the lighter bullets (155-175) do very well in the wind.
308, 155 Scenar, 2950 fps., -322" drop, 94" wind (10 MPH)
308, 175 SMK, 2750 fps., -397" drop, 107" wind (10 MPH)
308, 190 Berger VLD, 2750 fps., -328" drop, 78" wind (10 MPH)
308, 208 AMAX, 2600 fps., -352" drop, 74" wind (10 MPH)
Those velocities with the 190/210s are easily obtainable with RL-17.
