338 - Can't remember the load used but both 250 and 300gns.
Also some original Factory Winchester 338 ammo (? Silvertip ?)

Alan,
I find the 338 tends to anchor them, but does not "put them down" like a 375H&H does with the same shot. I have had one shot kills with the 338 (before insurance shots which I automatically do regardless) but I just don't like it as
much as the bigger cals.

Everyone's different which is what makes it interesting !!!

Woodleigh make a 250gn 318 bullet which is what I use.
You could virtually duplicate the ballistics using the
Woodleigh 240gn bullet out of the 30.06.
