Given a choice I would never use a compromise bullet on deer, instead I'd give it up on the coyote side of the equation. For me that means using the great 100gr Hornady SP or Nos.Partition in a similar weight.
I had a pretty good string of luck using the 95 gr Partition, & used it for everything when I was in the 24 cal game.
Imagine your grave on a windy winter night. You've been dead for 70 years. It's been 50 since a visitor last paused at your tombstone..... Now explain why you're in a pissy mood today.
Hands down my favorite 243 bullet is the Berger95gr VLD but it does require a 1-9"twist. If yours is not this fast of a twist then the 95NBT or the 70SBK would be my second choice. B
