Granted I'm not worried about any elephant here in Ohio, short of one rampaging out of the zoo or the circus. My brother poseses a weapon proven to take a elephant, a Thompson center Renagad in .54 Cal that and , according to a load book a 190gr charge of FFFG under a 500gr bullet can shoot through the shoulder!
This brings me around to two other questions. Now I think it was back in the late 80's or early 90's there was video of a rampaging elephant at a circus in Hawaii. It killed the trainer/handler and when it went outside the police were shooting it for ever with the 9mm's and buckshot out of their shotguns. In the end some body was able to down it.
I don't know with what or how.
The first question is this. Here in Ohio our "wonderful"

legeslators make this a shotgun only state (other than black powder) for long arms. Now we have just about every color of the rainbow, when it comes to slugs. Remington's coppersoild looks the meanest of the bunch. Has anyone, to anyone knowlage, known anybody to go after elephant with a shotgun loaded with slugs? How successful were they.
The next question is about .44 cast bulliets, I noticed in the linking articlal above, that JDJ moulds (which are no longer made) were very good on penitration. What are the best moulds/ commercial over the couter pre-cast bullets on the market for hardness and penitration.
