If I understand your question correctly it is can you get the same velocity from a TTSX bullet as you get with cup & core lead? In comparable weights the answer is yes. And the TTSX needs slightly less powder to get there. If it were me, I’d shoot the 150 gr. Bullet (your choice which) for all game up to Elk, and shoot 162/165 gr. Bullets (your choice) for Elk unless using a mono like the TTSX. Remember, monos seem to like speed for best performance. With a mono you can go with the lighter bullets.
