I didnt think the OP was looking at a custom? I thought he named a bunch of factory rifles he was looking into? My opinions in this case are based off factory options. I built my WSM to fit in a short action and throated it accordingly to the berger 180 elites. And my WM is set up for 215 hybrids. Factory to factory a WM is going to send heavies faster. Which in my book is more effective at LR hunting.
Here's a apple to apple comparisons. These are 200 grain posted max loads but I've tweaked both of mine and got more. Same bullet used on each chart.
Buy a tikka or Win. and throat it, it's not difficult. 180 in a short action throated or not still has the bearing surface below the neck shoulder junction. When doing comparisons take your WM throat it to a correctly seated 215 and do the same with a Tikka and your gonna find they probably will be close to 50 fps of one another. That's apples to apples
Here is the 180 data with same bullet. I actually shoot the 180 Swift Scirocco as my WSM just likes a steady diet of them.

It actually does put the bearing surface right above the junction on MY short action. MY not factory confingured short action. Which we are not talking about because its not a factory option that the OP can order. Im sure if he wanted custom chamber and custom action advise he would have asked for it. Thanks for the input tho. Now if you buy a CA rifle off the shelf like mentioned it will be in a saami configuration. Which means short action wsm.

You want apples to apples take a factory gun. In this case a CA in WSM and WM stuff a 200 class bullet in them in a length that feeds out of its mag. Now tell me which one sends that bullet faster. End of story.
Post #1 is he asking about factory guns. End of story

I hunted my 300 Weatherby for more than 20 years. I had it built in 1989 on Whitworth Mark X action coupled to a Shilen barrel. We have an agreement. If I point it in the right direction my baby does the rest. I also have 7mm mag, 25-06, 308, 338 WM, 458 Socom, 6.5 Grendel.................. but if it's bigger than a whitetail and smaller than a brown bear my 300 why is my go to rifle.
So you are calling a CA rifle a factory gun.
I've looked at 4 different load books and websites now and they all repeat the same data. Basically the WM and WSM cartridges are so similar it's laughable for a person to say the WSM is "not a capable" Long Range Elk cartridge. Look at the data, Hornady, Nosler, Hodgdon, etc. some shine with certain powders and bullets and the other may shine with a different variant. Both are very capable of downing a elk at long range. Both are capable of pushing a 200 grain at 3000fps. That being said I own both calibers and am happy with both. I've been considering one of the new Montana Rifle 300 Win Mag Long Range Hunter to replace my current rig. Good luck all.
It may not be your typical "factory" gun but that was one of the most desired choices of the OP. As a matter of fact he states he's probably ordering one on Monday.
