Funnily enough, yes it was my 338-06!
Normally I would've been using 210gr Partitions, but I left them at home...Doh. I had 2 properties back then, 4 hours drive apart, yet loading equipment at both.
So...I loaded up all I had, which was 225gr Accubonds I use in my 338WM's, sighted in that same morning 3" high @ 100mtrs. Nice clover leaf, so I was good to go, incident happened early next morning.
Yes, calibre does not make up for poor shot placement, that bullet only hit muscle and maybe the tip of one bone.
Cheers.
