I am looking for ballistic data for any of these three firearms. I am modifing a game that uses realistic ballistic data. I want to add either a 4 Ga shotgun, .500 nitro express or .600 nitro express. I would need mv, me and a bc for a common bullet for each.

Thanks

500 nitro = 570 grain solid at 2150 ft/sec, 600 nitro = 900 round nose at 2000 ft/sec, 700 nitro = 1000 grain bullet at 2000 ft/sec, 4 bore rifle 2000 grain bullet at 1460 ft/sec.
