Trying to Find/Choose the Right Caliber for Me

[Aussie Hunter Steve]

If you feel like a 270WM go for it…. There's a lot of satisfaction in having what you want, as opposed to having what you think you should have. And it's a tremendous cartridge!

I feel like you are limiting yourself, why just have one. Buy one now and another one later of the other caliber. I have safes full of the perfect calibers that is how I justify have all of them.

...neither ! Why drive yourself nuts worrying about ammo, casings and cartridge longevity for any cartridge for such a minimal gain ? A plain Jane ho-hum 7mm rem mag has and will stand the test of time and I guarantee will do anything either of those two can do with very little worry...life's too short for 100 fps.

I used the .270 Wby once and found it very impressive. Because .270 bullets (cup and core) are designed for the lighter .270 Winchester, they worked tremendously well on deer sized game. Lots of DRT's.
For heavier game, the Nosler 150 abd 160 grain Partitions are perfect. In todays market you can add the Barnes TTSX and LRX bullets.
I would urge learning how to handload. You will never be without ammo again. Cheap cases can be made from necking down and forming 7mm Remington cases. Buy, resize, load. Its that easy.
Handloaders have been using 7mm Rem brass necked down to form .257 Wby brass for decades. I first tried it back in the '70's.

For me, if I spring for a Mark V it's going to be in a Weatherby caliber so in your case I would take the .270 Weatherby. I have been looking hard at a Mark V for chasing pronghorns and it will be chambered in .257 Weatherby. I'm a handloader so ammo cost or availability is not an issue. Since you are a hunter and not shooting large amounts of ammo, don't worry about barrel life, just keep the barrel cool and it will last a long time.

Personally, I'd choose the 270 WBY Mag.

I went from not owning a Weatherby to owning 3 within a year.
One was purchased to be a safe queen.

I would advise learning how to reload. Makes ammo much more affordable (we are talking about Weatherby cartridges here) and accessable.
Starting out you are best advised NOT to be forming cases.
Hang in there and Weatherby cases will be available if they aren't right now.

Another thought....
I was a mechanic when I bought my reloading bench and press. They are tools to me. So I deducted them on my taxes.
Wish I could deduct components and firearms.

I'll be the oddball here. I would pick the 7 prc. Either will absolutely do anything you need them to do. Ammo availability and choices will be much greater. Ammo cost will be much less. If you're willing. We can do a custom batch of ammo for the 270, it will simply cost more and take more time.
If you do go with the 270, and it likes a particular factory load, I would buy a case or two of it and then not worry about it.
For bullet selection, 7mm will be vastly superior. As a loader, I much prefer the case design of the prc.
