Best All Around Caliber for Whitetail and Mule Deer?

Looking for thoughts on what caliber you guys would pick as the most versatile caliber for western whitetail and mule deer in factory offerings?

Thanks,
Mike
For a Western hunt, which going to usually end up with shots at longer ranges I would recommend a 270, however another new cartridge that would also fill the bill without going overboard is the 6.8 Western. Heavier bullets, less recoil, great accuracy and a lot of knock down power. I have a 6.8 Western in a Winchester XPR that shoots sub MOA at 0.6 to 0.7 all day using Winchester ammo.
 
This is for deer only in western states . Never seen any mule deer running around on the east coast side of the USA. 😄 I have been torn between a 7mm mag, 270 win or a 300 RUM. Wanting opinions from those more familiar with the area out there. I know not one caliber or bullet covers it all. But I have long favored the 7mm mag with a 160 Nosler partition for most all conditions.
Just to clarify I'm from the east but I shoot a lot of big bean fields and most of my shots fall between 250-500 yards. I can't imagine mule deer being that much tougher than a whitetail or large boar hog. The 270 with the right bullets will do the job. The 7 mag will too and you don't have to run it wide open either. The 6.5mm cartridges work very well. Especially in the 6.5-06-6.5prc range which includes 6.5-284. Most any cartridge in this range will work if you do your part.
 
I would say "no such thing" as best. For 95% of all scenarios, there is not a whitetail or mule deer on the planet that is going to tell the difference between 2650 fps - 2950 fps, 130 grns to 180 grns, and .044 of bullet diameter when a bullet is placed into the vitals from 0 to 600 yards.

There isn't one. However imho 7 mm is the sweet spot between bullet weight, bc and sd. There is a reason the 7 mag was a huge hit. One of the few things remington did right. A fast twist 7 mag or 7 prc is hard to beat.

If I was strictly hunting deer, 257 Weatherby Mag followed by the 25-06. If I was trying to shoot them at over 800 yards regularly, 7 Mag of some sort because I can get much higher B.C. bullets.

Never used any of the Man Bun cartridges so can't speak to those.

Most of what I've read here comes down to personal preference. I too have shot deer with a variety of calibers. However, most of the deer and antelope as well as coyotes have been shot with a 243. The companies that provide ammunition have covered all the bases from deer to prairie dogs with the 243. It is also readily available. You can find it in nearly every gun shop and convenience store in the country. And yes, there are many other calibers that will get the job done. The 243 just happens to be my personal preference.
 
Easy option- 7mm Rem Mag or 270 Win
Classy option - 257 Weatherby
Enjoy the journey and your hunt when it arrives.
Good luck and let us know what you decide.
I mean you really can't say it any better. Have used all three plus others and those are the top 3 for sure. If I had to choose one I'm taking my REM bdl 270. 22" barrel and all. We call it my rabbit gun but it drops elk/mule deer faster than my brothers 300 win mag 🤷
