Terry,
6.5lb w/o scope is what I read. So, you're probably right.
I have a brake on my 7mm RM Sendero. I don't know the weight. But, I'm sure it's much heavier. It's a real pleasure to shoot 20 rounds at 500-1,000 yds.
If you like the rifle and think it'll work, you should buy it. Unless you plan to compete, the only person you have to please is yourself. You can hunt just about anything in North America.
