30-7mm WSM?

[cjl2010]

I guess I must have missed it too...
Spend a pile of time and money to take an efficient case and blow it out increasing the capacity 6-8 grains.
Now you have a case that uses nearly as much powder as say a 300 PRC, but you still struggle to run the same velocities..
Sorry where's the benefit, or efficiency?
Sounds fun if you have nothing else to do with your time and money

Agreed, if your just having fun im all for it. The only brass is Hornady and Bertram I believe for 7wsm. I would think you would have a fairly shortish neck.

I hope you build it and it's awesome though.
