If floating a barrel is better for accuracy how come so many guns are around that you can not put a bill under the barrel ..
If floating the barrel is a good thing why do they not come from the factory that way ..
They have to fit the stock .. Why not take out enough wood to allow the barrel to sit in the stock and the barrel and stock not touch .
What if you have a gun with a pencil barrel .. Does a stock that is not floated .. Help to SUPPORT the barrel
I am getting a feeling that you came into this conversation with a preconceived notion and want support for it.
First, free floating is done to create consistant, static, or perfectly repeated harmonics. This gives consistancy, which is the foremost ingredient to accuracy. I run all of my rifle freefloated, wood or plastic, fiberglass and graphite for this reason. Full bedding and forend pressure can do the exact same thing, but are more difficult to accomplish well. Melvin Forbes (NULA and Forbes Rifles) is probably one of the only folks most could name that still does this with all of his custom and production rifles. And they are hand fitted.
Now saying "if thats what is best why dont the factories do it" is a terrible arguement. Why doesn't GMC blue print every motor that leaves the factory as it gives longevity and more consistant and increased performance? Money. The cost of each vehicle would rise by $5000k and the average driver couldn't (that word was used deliberately) percieve the beneifit.
The same goes for your statement. The metal comes off the line at one end of the factory, and the stock another. The is a guy that takes the two and assembles them with a torque wrench and out the door it goes. Maybe they'l squirt a shot of hot glue like substance into the bearing area at the recoil lug so they can say "bedded" in the advertisement. They don't "fit" anything. If they did, your $900 CDL or $700 Savage would suddenly cost $150-$200 more. And frankly, you're not willing to pay for that.
The more expensive production rifles such as Sako, etc. do free float their barrels and take some time and that is part of why you pay $1800 for one.
As for the pencil barrel thing, the answer is in Melvin Forbes; products again. Yes, the barrel is supported positively when the stock is properly bedded to the barrel without pressure and evenly. If it isn't, that is support that is binding, and it is a negative thing.
