Whats the concensus on getting the really lightweight barrels to shoot-freefloat, full bed, forearm pressure???

Freefloating has always worked for me. None of my rifles are full bedded or pressure pointed. In the 2 lightwts I have, the point of impact starts to change after three quick shots. After cooldown, it returns to its original zero. If I haven't done it in three shots, it's probably too late anyway.

Pedestal, I always float light barrels first and try them that way. If they don't work floated I'll try full-length "neutral" (no upward pressure) bedding (this is the way our local smith and lightweight rifle guru Dave Gentry does his). I WILL NOT bed a barrel with pressure and will sell/trade/re-barrel before doing so... it's nearly impossible to replicate the pressure when taking the action out of the stock and putting it back in. Also, using a "tight sling" can alter POI with such a set-up.

Free-floating doesn't always work. Some lightweight barrels need some upward pressure in the forend to dampen barrel vibrations for best accuracy. ALL barrels are individuals, and you need to try different things if one isn't up to your standards at first.

Everything here is full floated, and they all group well, including my son's 77/6m/m, rifle barrels don't get much lighter than this one and it shoots very well indeed.
The only exception to the previous statement is an 82 Kimber that shot well right out of the box.
I'm with Brad on this one. If it won't shoot floated,i'll make sure the action is bedded properly, and if it still won't shoot, the barrel is likely junk for one reason or another. I used to think a rifle had to have a bull barrel to shoot, but that is not necessarily so. I'm speaking about general purpose guns, not benchrest.
