I liked the core lokt bullets you were looking at...a while back for game animals...they are really deadly, they expand very well and are cheap....especially if you hit the lungs every time. I don't care what anyone tells you..you hit a eland in the lungs...it isn't going anywhere. And hitting a animal in the lungs doesn't ruin meat...and animal can't live if it can't breath.
The problem with FMJ...is they don't expand....and unless you hit the shoulder bone or lungs or heart or head...you are possibly going to have a huge problem getting that animal. I think of FMJ...as a sword...in the right spot deadly...wrong spot (big problem).
