I have had good luck with the core-lokt, no matter the game.
I do seem to get a little bigger exit holes and a little better penetration with the round nose soft point core-lokts.
RNCLSP tend to be heavier weight for caliber and still have the heavy 'hour glass' jacket shape, as I found in the 165 gr RNSPCL remington has for its own .280 in recent loads. The other 140 and 150 grain pointed core-lokts loads do not have the heavy 'hour-glass' shape.
Have yet to have one turn to vapor upon contact with big game and tent to be my 'go to' in factory loads when available.
