I'd avoid Remington Thunderbolts like the plague.
A friend of mine just bought a new MP-15/22 and after less than 100rds he thought his scope was broken...I'm talking 4 FOOT groups and keyholing at 50 yards.
After inspecting the barrel he found it was leaded beyond belief.
I'd never seen anything like it before and did a quick Google search when I got home. It seems like he isn't the only one with this issue.
