I am currently shooting 30 caliber SMK 155 gr. bullets out of my F-Class gun at 1000 yards. Each time I measure them from base to bore diameter, the lengths are all over the place,I guess due to different machines). This seems to be causing differing BC's and thus differing verticals at 1000 yards. With the new F-Class targets out now, I need a better bullet. My barrel is a tight,.298") Krieger 30" long and the cartridge is 308 Winchester.
Ideas?
