I would also agree that the .243 WIN is a great deer killer. The only thing that makes me wary of it is how many people who own them seem so interested in the subjects of premium bullets and bullet failures.
Any centerfire rifle cartridge will kill a whitetail. If you look towards the middle of that spectrum you see the .308 bores. If you go up or down from that you can see the trade-offs in things like velocity, energy, effective range, recoil, etc. Deer are similar to humans in size. That which kills humans well at a given range also can kill a deer. If you look at what the world's engineers came up with in the late 19th century as a response to smokeless powder, you can see pretty much the epitome of not only military cartridges but also deer killing cartridges. However, they were predicated on a bunch of things we as hunters do not generally have to face. We don't have to worry about load weight-- we carry only a handful of rounds. We don't have to worry about the other side firing back. Somewhere in all of that, the world's armies mostly armed themselves with something close to a 7.62mm rifle.
I'm not saying the .30 calibers are IT. I'm not saying 30-06 or 300 Savage are IT. What I'm trying to do is establish a continuum with these sorts of rifle calibers at the center. It is isn't the best-- it's just a convenient starting place. From there, you can talk about the trade-offs. One guy wants more velocity and is willing to trade bullet mass for it. He buys a 25-06. The next guy wants lots of mass and doesn't care about anything else. He goes and buys a 45-70. By the time you get down to the .243/6mm realm, you have optimized about as far as you can go for light recoil and flat trajectory. What is given up is bullet mass and retained energy at a distance. Does this make 243 WIN weak? No. Does it kill deer? Yes. It is the single best selling deer cartridge in Britain. I'm not going to try and take on that crowd.
Me? I generally stick in the middle. I am also a reloader and I frequently knock off a few grains to make my 30-something rifles recoil less and cost less to produce, but still take deer. Flat? What do I care about flat? I have a hard time seeing out past 100 yards in my cedar woods, so what's flat to me? My rifles are set to shoot 2" high at 100 yards and they're good to go out to about 225. That's just fine for me.
.243 WIN. If I wanted to stick it in a deer's ear at 200 yards, 243 WIN would be a good choice. I know that, because I have a neighbor who likes to do just that. If I were shooting my Savage 99, I'd have to be absolutely sure of the distance-- from 200 to 220 yards the bullet would be sinking 3 inches. On the other hand, I once shot a deer at 5 yards with a 30-06 180 grain. It was freak thing, a doe ran into the path of the shot on a buck as I was pulling the trigger. Not only did the bullet hold together, but it went from just under the tail all the way through and came out between the shoulder blades, carrying a couple vertebrae with it-- all this without disrupting the innards. Fluke? Yes. Do I deliberately go out and take Texas Heart Shots? No. Please, hold the flames-- it was my first deer. My point is simply that in the vast array of what's out there for deer, everyone has trade-offs.
While I'm on this, have a look at the 358 WIN. It is what you get if you go to the other end of the spectrum from the .243 WIN. It's what you can do with a .308 WIN case stretched in the other direction. Where the .243 necks it down to take a 6mm bullet. The .358 WIN stretches the case to take a .358 bullet (same as a .357 magnum pistol or a 350 Rem Mag) Look at what that buys you versus what it costs. The .243 WIN is a light round that will double as a varmint load. The .358 WIN is a deep woods deer killer, the 35 REM on steroids, and is not under-powered even for elk or bear. It has lots more retained energy, but it sacrifices flatness. Instead of a deer/varmint load you have a deer/bear sort of thing going on. By the way, I load my one rifle in 35 Whelen to mimic the .358 WIN-- it's an awesome deer killer too.
