The 243 with a 90 grain Ballistic tip or Accubond will be traveling at about 1900 FPS at 500 yards. It will smash bone, penetrate deeply and cause catrastrophic vital tissue damage at that range/velocity, and there is nothing marginal about it.
You wouldn't be able to tell the difference examining tissue hit by a 243 at those ranges and a 7mm-08 at those ranges.
I'd venture a somewhat scientific guess that the majority of shooters would be better served by a 243 at those distances than a 30-06 or a 270. It's no secret that shooters shoot lighter recoiling rounds more accurately that heavier recoiling ones.
Lol, somebody drank the koolaid. MV is going to be closer to 1700fps at 500yards but lets say you are right. 720 ft/lbs is marginal for deer no matter how you cut it, and you are lucky if you get any kind of bullet expansion at all at that velocity.
At 500 yards all it takes is for that animal to take one step forward like I was saying, or one step to the side, and all of the sudden that bullet now has to power through a shoulder. Or punch through the gut cavity.
Yea. I'll bet they both are marginal to poor performers at that range. Thats why I wouldn't hunt with EITHER a .243 or a 7mm-08 for anything larger than antelope or further than 250 yards. YMMV.
I'd offer the opposite opinion. I think people are still as capable of accurately shooting as powerful of calibers as they always have been. 30-06 and .270 are more capable cartridges than the .243. My first deer rifle at age 12 was a 30-06. There are better options for deer cartridges out there for recoil sensitive shooters than the .243.
If my eyebrow goes up any further it's gonna be behind my ear. A 90gr bullet isn't gonna "smash" anything but a prairie dog.
90gr Speer .243” “HotCore”. Muzzle velocity of 3,200fps.
Range: 90yds.
Bullet failed to exit.

‘Yote dropped at the shot. Shoulder/spine hit.
Not exactly big deer or elk medicine!
Another shot at exact same location with a .270 w/130gr HotCore was a MESS!
1” blow out entry wound, 4” dia exit wound.
I agree! @357smallbore asked about 243win at 300yards or less with a 100 grain Partition for mule deer. He is picking a well designed bullet to get the job done. I believe that he is going to be responsible and respectful to the game he shoots at with good shot placement.I think the discussion has evolved into something other than what the OP asked. The OP didn't ask if there were better cartridges for mule deer, he asked if the 243 Win could do the job. I believe based on my personal experience that it can. Will a bigger caliber be better? Under some conditions the answer is yes, but that was not the original question.
I would say one's ability to shoot accurately far out weighs the cartridge selection. 6mm with a good bullet would be my minimum however.
I used to hunt with a guy who grew up hunting in Montana. He shot everything with a .243, including mule deer, with that rifle. I know it's possible because I saw him do it. Shot placement was his ace in the hole.
It's actually a little more than half but illustrates exactly why we need to be ignoring energy figures entirely.The energy that you are scoffing at is what an average 240 grain 44 magnum has at 25 yards when fired from a handgun.
My experience is exactly why I no longer own a .243 or any other 6mm.Tell me about your experience with 90 grain bullets on deer. Have you done any in depth reading or research?
Not about misses or gut shots. A more capable cartridge is more forgiving of less than perfect placement and allows greater flexibility in presentation. I wouldn't expect a 6mm to make it through any deer's shoulder with regularity.When is shot placement not the ace in the hole? I am somewhat amused by the emphasis on shot placement with smaller caliber rifles. A miss is a miss. A gut shot is a gut shot. A liver shot is a liver shot. Animals don't magically give up the ghost to a gut shot with a 300 magnum.
Where can you hit them with a 30-06 that you can't hit them with a 243 with similar results?
If you're gonna use it, the Partition is a good choice. I still wouldn't hunt mule deer with such a pipsqueak cartridge.I agree! @357smallbore asked about 243win at 300yards or less with a 100 grain Partition for mule deer. He is picking a well designed bullet to get the job done.
When using a marginal cartridge, placement has to be perfect and it needs to avoid any major support structures. No shoulders and no Texas heart shots.Have lost track of number of comments that mentioned "right shot placement". I hear that a lot with references to 243.
Where exactly is that shot placement. What is the aim point? What do you hope to hit?

A broadside shot that turned into a quartering away shot because the animal took a step to the side as you were pulling the trigger. Now you have to power through a foot or two of gut cavity before you reach the vitals
A non-factor for a cartridge like a .270 or 30-06
A bad scenario for that .243
I already did. 100gr bullets blowing up on the ribcage of an 80lb doe.Give some specifics of that experience if you don't mind. When, what bullet, where did the bullet impact, number of instances of substandard performance.
A 243 pushing a 90 grain NBT, Accubond or Partition will make it through a deer's shoulder EVERY time the impact velocity is in the 1800-1900ish range on up.
What would you consider to be the minimum caliber and weight that for a Partition to work on mule deer? Upon what real world experiences or research do you base that decision?
I was very clear what I meant. As I said, it's not about hitting or missing. In my opinion, the diehard .243 fans operate in a vacuum. They're in the habit of waiting for that perfect broadside shot or they don't shoot and they think it's the only way anyone hunts. As a handgun hunter, I'm quite accustomed to having the option of breaking a shoulder or taking quartering shots that would not be advisable with a pasture poodle cartridge. I want an exit wound. Bullets that fragment and don't exit give me the willies.What do you mean by perfect? Do your best to qualify that for me. It might be best to tell me what organ you have to hit with a 243 that you could miss with a 300 magnum and expect a humane kill.
Yes, I did and if a bullet fails on whitetail doe, is it going to do better on bigger deer? I was unaware that we could not hunt outside our home state.You didn't tell us about your experience.
I've never heard of anyone hunting mule deer in TN.
