What bullet, propellant and speed?

I am not with books, but memory will be very close. Peregrine bullet made for me and this gun - copper  260 gr bullet with a hole in front like a pencil thickness and more than half length of bullet. S265 propellant at 24?? fps.
very poor BC and Sd, but makes a very big clean hole.

A 'flyin trashcan'! This calibre is intriguing me.

QL agrees with your guesses.

S265 at 51 gr gives between 2447 and 2487 fps for Impala Kriek and Peregrine 260 gr bullets.

************************************
We needed a very big hole at not more than about 80 m but usually 10 m  or so for bush pig stalking because we were scared wussies. We also shot pig over bait at night, also at some very close ranges. The pig at night were with sub sonic loads and flat point lead bullets.
The w/hog and general hunting evolved later.
