There is a guy over at Marlin owners who has been successful on deer using the Sierra 125 gr HPFN bullet and has posted post mortum pictures of the internal damage. I'd say you be good to go.
I have a load worked up for my Marlin 30-30 using CFE-223 using the Sierra 125 gr bullet...just have hunted with the rifle yet. The bullet shoots under an inch for 3 shots at 100 yds
