Having shot a fair few BG / DG - as in Water Buffalo
and Scrub bulls and a fair few pigs with smaller cals, one thing is for certain.

Animals do not stand perfectly side on or present the perfect shot for you. Going on from here, you therefore have to make a judgement on taking the shot.

I use the 5th rib rule, which is if I can see the 5th rib, because I use a bigger calibre and / or a heavier bullet,
I know that I can take the shot because even if I hit the rib, the bullet will still get to the vitals. You just can't guarantee that with lighter bullets.

Just my HO.
