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.
