If you look at the thread (gunwriter subforum) on the Schiuchetti .30 cal bullet chart the 180 GS did very well.
Speer revised the bullet, construction-wise, at least once tho.
Bought some revised .375" 285s. Mediocre accuracy even compared to the other Speer offerings. Noticed COAL after seating was variable. That's because ogive lengths are all over the place, which has the effect of creating varying distance from bearing portion to rifling. Dunno if it's contributory, but doubt it helps.
Certainly good enough for 250 yds, as far as I'll shoot them.
