thats the ogive thats important... i plan to stay in the "12 ga from hell" type world, using 50 bmg cases blown out to ras 12 polymer shape... ive used them in past and shot some lee buckshot that was RTV'd in, but that process is less than ideal and the round really needs that outer polymer nosecone (which i cant find replacements for, allegedly was a model rocket nose cone, but i cant find any) so if a guy could just match the ogive of the original plastic nosecone and make a good balanced slug design i would be a happy camper...
heres a vid of some brass being shot... sounds cool when it hits the ground!
