I've used them in my 308 Win and the published BC seems correct as compared to Ballistic Program predictions. My new, soon to be finished, 300 WSM
is going to shoot the 175 Sierra and the 155 (154 on your side of the pond) Lapua exclusively.
Externally the two bullets are quite similar, same (plus or minus) length and if I recall same bearing surface. I get about 2850fps I believe with the 155 in my 308 Win...could be less as my memory sometime makes up numbers to fool me.
Maybe Ric needs to run some through his new 300 WSM for the betterment of the entire population (take one for the team ya know)!
