Yes the 375EX 2-1/2in seems like it has a heap of power for animals under Buff, even then with good shot placement & bullets it would work on them to .

I don't think those Westley Richards cartridges would fit in my Lee Speed 375Ex's mag by the looks of that bullet loaded in them, nor my Styer 375EX clip (when I get hold of it) ?

If I could get those Barnes Originals in .378 here I would give them a shot

in my Speeder's worn barrel, Hornady 270's tumble, but the Wooleighs shoot point on .

Good luck with her !
