No surprise from me as 100 grain Ttsx will punch through a big red stag breaking both shoulders with my 260 rem and still exiting at ranges over 300 yds commonly / to be expectedT3 .308 with 22.5” barrel. 130 gr. TTSX, Lapua cases, 47.1 grains N140 = 2,904 fps mv. Very accurate and terminal effect excellent on fallow, roe, CWD and muntjac. Bullet passes through every time.
