A rifle like a 243 will have far more power, range and accuracy than any bow. I am a senior 6' tall with strong hands and a rifleman of over 60 years experience. I like the new to me crossbow as my state made them ok now for deer. I like playing with it in my basement and I shoot it every week down there.
Even a reduced load in a 243 would be much easier to hit with however the crossbow is fun. You can try both.
