303,

A 375H&H is devastating on pigs - it absolutely flattens them with 270 and 300gn bullets.
(I haven't shot any with 235gns but would expect it to have the same affect.)

Technically it is a bit of overkill or as you say "it was too much gun"
but since most people like me just shoot to kill them and not shoot them
for the meat, does it matter what you shoot them with ?

I shoot them with what ever I have in my hands - be it a 222 to a 500 Nitro.
