The .243 is what most would call "marginal" for deer, but in the right hands it can take deer well. But be prepared for tracking deer no matter what round you choose.

I am a professional deer stalker/manager over here in the UK.
although I do admittedly use .308 for large deer and 200yd+ culling (only when absolutely neccesary) I mainly use .243 for general stalking/accompanying clients etc. IMHO it is more than suitable for the job, easily taking even large red-deer out 200yds when neccesary, I did look into a 25-06 (as in an earlier post) but I will stick with .243 & .308 for now at least.
Shot placement is the all important factor, cario-vascular (heart'n'lung) shots are the best to go for (although even with this shot the deer may well "RUN-DEAD" for anything upto 100mtrs, due to adrenaline)
Upon the bullet striking the chosen target the beast's reaction to shot, if carefully observed will 9 out of 10 times tell you hit the desired aiming point or not:-
HEART/LUNG SHOT - deer will (usually) make a high bound forward/ or kick out with it hind legs, this shot will also produce a bright red frothy blood trail with pink/white flecks of lung tissue in it.
STOMACH SHOT - deer tends to hunch-up and staggers away into nearby cover with head held low, this shot usually produces a lot of green-splashes of rumen from the stomach content sometimes with a lot of pins (hair) and very little blood at all.
LIVER SHOT - deer tends to run with its head well forward and is usually dead within 100mtrs, the blood trail tends to be very thick and glutinous and very, very dark red.
I assume US deer (although a bit larger than ours generally) die just the same :wink:
I hope this may be of some use
