I have real good luck with flatbase bullets in 30/30 & some 308. I do not shoot at extended ranges though, where they say the bts are superior. I use bts almost exclusively in 223 because that's whats available and cheap. Actually I think that FB bullets may have an advantage over bts at ranges less than 150-200 yards.
