180 XTP's
From a carbine, my experience is that the 180 XTP is too soft, and borders on frangible, especially at closer ranges. See my comments regards a buck shot broadside at under 10 yds in another post. That slug just fragmented. Another with the same load, slipped its jacket, and was found in two separate pieces, core and jacket. Two dead deer, two recovered ( well sort of) slugs. HOrnady describes the 180 XTP as expanding at lower velocities, and at the speed a carbine can generate, they are frangible. None of these hit major bones, all ribcage/lung shots.
The 200 XTP do not seem to consistently exit either, but I have recovered two of them, intact, with complete, near inside out expansion. Much better.
I have never seen a 240 recovered from a deer, either the 2-3 I have shot with that weight, or the 10 or so my dad killed with a Win 94 and 240's ( of mixed slug type)
