this is just a question. im not trolling,im not planning on using this in Africa, i just want to hear from experts. a double rifle expert told me in the pre nitro days a hardened 8 bore ball at 1500 fps was deadly to an elephants head with a frontal brain shot.. On that statement, i ask my question. A souped up rifled 20 gauge slug gun i know will push 700 grain/.550 CEB bronze solids at 16-1700 fps/over 4000 ft lbs.. Due to the smaller diameter,decent sectional density, and faster velocity than what the old 8 bores used to do, do you think a .550/700grainer going 1600 fps would penetrate an elephant for a frontal brain shot? Im asking because im impressed at the souped up 20gauge, and am just curious if that load would do the trick. As i said, this is just a question. If I was going to Africa id take the Lott. thank you for your time and patience with questions about a load.
