wildboarHow much free floating on a Target 308W Heavy barrel?
Hi, how much free floating is enough? I mean, the minimum space needed between barrel and stock.

dsitemanMany match/target rifles will have what seems to be a large amount of barrel channel matrial removed and nothing wrong with that other than somewhat an ugly appearance. Good compromise would be in the area of .125". Some use double thikness of paper, approx. .008" and consider that suffecient. For the long 30" Palma type barrels I would bed the area of the chamber and leave the rest free floated. Worked fine for me and with all of that suspended weight of the long barrel, it tended to avoid any action flex.

Unless the stock is warped and continues to move away from the barrel as I cut, I will open the stock to a point where I can no longer hear or feel the stock slap the barrel when I give the bottom of the forearm a whack with an 'open hand'. Wouldn't want to be accused of Assault.

LongshotThe reason for excessive air space is for cooling. Long range matches may be 20 or more rounds in 22 minutes. Here in the south it was 104 degree on the range in June.

eddieharren#1 for Wespac. If you can "slap" the forend and, make it touch the barrel, it is not relieved enough.

dsitemanHello Longshot,
You are certainly correct in the space for cooling, forgot to mention that. I know of the heat in shooting at Buntner and Oak Ridge for some years. Good point.

wildboarGood points, this forum is an invaluable source of knowledge! My barrel is
probably not relieved enough; thanks.
