A few years back I used a 10" Bull Barrel Contender in 7-30 Waters. Without the added length of the Muzzle Brake that is about what you have. I would have to agree with the others, give it a try before you decide to sell it, the 7-30 Waters is a great cartridge and right at home in the Deer Fields.
In my 10" 7-30 Waters Barrel I used the 120gr. Nosler Ballistic Tip handloaded to a muzzle velocity of 2258 FPS. I took 3 Whitetails with this barrel / load combination, and my cousin's husband used it to take a 4th Whitetail that particular season. All were One Shot Kills at a variety of different ranges from 40 yards to father than I will discuss here.
The 7-30 Waters is a great cartridge, it is easy to load for, mild to shoot, and just plain works good.
Try it, I think you'll like it.
