[QUOTE="kimba, post: 1029506, member: 85888"] AS I said before the pencil barrels usually shoot well with the pressure point - not always but most of the time. Conventional , modern thinking is all needs to be free floated and folks take that and run with it without testing it. Most heavy barrels do do better free floated and so folks assume that is how all barrels shoot as that is all they ever read about - kind of like" x fps second loss per each inch a barrel is shortened ( a thing proven not to be true depending upon burn rate of powders). There is no set rule and experimentation is required. If as stock is fairly rigid and the barrel is a pencil, it often shoots better with that pressure point. Due to the crappy stocks being often shipped with factory guns ( too much flex), many light barrels may actually shoot better with free float. Folks with remcrap factory stocks or Tupperware sav,tika, ... have free floated pencil barrels and seen improvement. Smiths often do same thing and just float it as it is the easy way. Most high end stocks are used by folks with heavier weight barrels as if they are willing to invest in a $700 stock, they usually also invest in an other than pencil weight barrel as they like to shoot a bunch and do not want to deal with fast heating of pencil barrels at range - and heavier barrels just shoot better in terms of accuracy all quality things being equal. Thus the " all barrels need to be free floated myth gets ingrained. You gotta shoot it to tell and look for shot stringing as it heats up. YOu can remove it and test - if it shoots worse, just build the pressure point back with epoxy. [/QUOTE]
