It's funny you mention this. I just talked to some gents on "Predator Masters" about the BLR a couple of days ago. They were talking/complaining about the newer models with plastic gears and bushings.
I also have one of the older models. Steel receiver and clip and straight grip. I inherited it from my dad, so it has a lot of sentimental value and see's little use.
In my dad's quest to get the most from his .243 lever gun, economically and ballistically, he contacted a few companies trying to get it re-barreled. The only company that would entertain the idea was McGowan Precision Barrels (McGowen Precision Barrels, LLC Home
) and they did an absolutely fantastic job of it.
My dad had a CM, 26", slim Varmint profile barrel installed. I think it's a Douglas barrel. I haven't shot it very much at all, but it shot with bolt action rifle precision when he first got it.
Who, smith wise, have you found to rebarrel yours? I don't see why this action wouldn't handle the 6.5x284. JohnnyK.
