Any advantages of the 300/7mm wsm?

I am in the process of building my second ever custom rifle and wanted to get some feed back from some guys. I was wondering what the advantages or disadvantages of a 300/7mm wsm would be over a standard 7 wsm. The one thing I can see right off the bat is that the 300 case has a longer case neck which is always nice, and that brass will be easier to find. Are there any other advantages or disadvantages? One of my main questions that I haven't been able to figure out is if I will gain or lose case capacity and how velocity will be affected. My gunsmith is having to order a 7mm wsm reamer throated for 168 vld's, so I got to thinking if there was a true advantage why not go ahead and get the 300/7mm wsm. The gun is being built on a stiller predator long action and a hart #7 1:9 twist. Any other advice on the gun or caliber is welcome also. Thanks ahead of time to everyone who responds.

I don't own either, but from what I have read the 7mm WSM should offer a slight advantage in volume since the neck is shorter. However, the shorter neck is also a disadvantage as you have stated. So its the short neck with greater volume or the long neck with reloading advantages. I don't think you can go wrong with either.

longer neck with the 300 WSM brass, only a touch less case capacity (longest neck is on the 270WSM brass). I shoot the straigh 7WSM. A bit more neck would be nice, but is not affecting me as far as I can tell. I long-throated my current rig to get teh boat tail junction above the neck/shoulder junction and you could easily do the same to maximize capacity in the 7/300WSM

7mmWSM brass can be made from 270WSM or 300WSM brass with a simple neck size and fireform.

I use Norma brass in mine.
