I just got 2 boxes of ammo,to see what shoots better out of my gun, federal tipped expander (Barnes) and Winchester Supreme Elite XP3. I have a Mil dot scope with Turrets. I found a website to give me my click for a dial in, but I'm not sure on bullet info. I need the BC and caliber of the bullets to punch in the info to get as accurret as I can. I didnt see that kind of info on thier websites. I'm guessing there a .45 cal bullet and BC is around 200. The Velocity are close to whats listed on thier box, but I want to crunch the numbers exact. Anybody else shoot one of these? Like to know how you like them.
