I shoot the Lapua for everything but game. I use the sierra for killing. In my 338 edge, the Lapua is more consistant from 1,000 yds. out to 1,500, and beyond. I like the nose profile better and the trimmed meplats and point forming die they use I think makes the difference. Besides it looks more accurate and to my way of thinking adds confidence when the tips are uniform, not jagged like the sierra. Also, the doppler radar figures on lapua's web site list the B.C @ .825. Sierra is .768.
Not to hijack your thread or change the topic, but I've been shooting the Hornady 250 g. BTHP match for a couple hundred rounds at 1,425 yds. and they are really consistant also. B.C. is .675
