Rod had good results in penetration tests on the 225gr. Hornady's sized down to .367" as well as the 235gr. Speer, sized down the same. They acted like much tougher bullets, I assume, due to the reduction in size, which would have thickened up the jackets some more.
Speer thickened up the jacket on the 235gr. .375's some time back and they worked well for buddy Keith on moose up here in B.C.
The .270 cal. 130gr. TTSX did well in his wife's Parker Hale rifle on Kudu.
