Welcome to the campfire 101guns.
The 7-30 Waters was developed to try and get a flatter shooting cartridge into a lever action. It's just a .30 WCF necked down to 7mm. I don't know of any bolt action ever being chambered for it.
There really isn't any other niche for this cartridge. If you want a bolt gun that shoots a 7mm in a similar velocity get a 7mm-08. With the same bullet wieght the 7mm-08 gets about 250fps faster.
If you gotta have a 7-30 Waters go for it. I don't know of any major ammo companies loading for it though. And your probaly gonna have to make your own brass for relaoding. If you don't reload I'd drop the whole idea.
I can see no advantage in getting a 7-30 Waters in anything but a lever action. If you don't like levers though you probaly won't like good advice either. Holding a nice lever gun is like holding a pretty girl. Damn sexy rifles.
Good luck.
