Blue is the Lapua 155gn Scenar factory load
Green is the Lapua 185gn Scenar factory load

Note the starting velocity, I suspect from a 24" or 26" barrel. I picked a zero range of 300yd

You can notice the wind drift differences in the two bullets. This was for a 5mph wind

I can say I like shooting the 175SMK's at 1000yd more than the 155 Bergers. I can adjust for wind easier. I also think the heavier bullets make for a lower ES/SD for me, which results in smaller groups. The only thing I have to overcome is the recoil. I am not consistent enough with hold (12lb rifle) over a long string. Which is why my 1000yd gun is a 6BR these days. :)
