Over the years, standard factory loads for the .30-30 Winchester included 150 cereals and 170 grain flat point bullets from either JHP or JSP. The ballistic coefficient (BC) for the Speer 150 grain bullet is 0.268 and the section density (SD) is 0.226. For the 170 grain Speer bullet, B.C. is .304 and the SD is .256. The standard 150 loads of grain plant from large ammunition businesses have a muzzle speed (MV) of 2390 fps (previously 2400 fps), and 1,902 ft. lbw energy muzzle (ME). The 170 grain load plant has AN MV 2200 fps, and a ME of 1,827 feet. In addition, Winchester offers a premium High Load Factory with a 150 grain Power-Point Plus bullet at MV 2480 fps with 2,049 ft lbs. The plant loaded 125 grain bullets at 2,570 fps and 160 grain bullets at 2,300 fps are sometimes offered. And Remington offers their Load Accelerator, 55 grain .224 PSP sabotaged by the bullet on the MV 3400 fps. Conventional plant slugs loaded for .30-30 have a flat dot or round nose design (except for the Remington Accelerator varmint load) because the cartridges in the tubular logs of the traditional Marlin and Winchester lever-action rifles ride in a straight line, with the nose of a single bullet touching the primer round in front of it. Note, however, that the ballistic coefficient for the 150 grain flat point .30-30 bullet is slightly better than B.C.
