Regarding relative bullet lengths, here is a sampling of .338 bullets. The recovered bullet is the one 160 TTSX I’ve recovered. It was in the very thick offside hide of a Waterbuck. The 185 TTSX has also worked well for me, but I do believe the 160 does a bit more internal damage. Splitting hairs, but I prefer the 160 to kill things.
The bullets left to right are:
