My boy shot a really nice 25" mule deer the other day with his 243. We messed with him for a couple hours over 2 ridges in burned standing timber. Finally got a decent shot at 306 yds. Shot was prone. Entered at the base of the neck , through the off side shoulder. Buck never took a step. Fell over with his legs in the air. 95 grain nosler ballistic tips. Excellent deer bullets. My 2 boys and I have killed 8 or 9 big mule deer with a 243, at ranges from 50 yds to 410 yds . Very lethal, low drama.
