Glass Bedding
The object is to make perfect contact in all critical areas of
the receiver to the stock.
Why:
- Enhances the ability to torque the receiver in place.
- Greatly reduces the chance of shifting the bullet impact related to temperature
and humidity changes.
- The receiver stays in exactly the same position shot after shot.
Note: If all things on the firing line (i.e. shooter, rifle, etc.)
stay exactly the same, the bullets leave the barrel exactly the same on the way to the target. Bedding greatly increases
the chance of hitting the target in exactly the same place.
Floating the Rifle Barrel
Floating in gun talk means the rifle barrel is not touching any place in the
barrel channel of the stock beyond the barrel shank. Sometimes the barrel shank is also floated.
If the fore
end of the rifle stock warps or moves because of temperature or moisture changes, it will push the barrel, changing the point
of impact. If the barrel is moved .001 of an inch in the stock, it would change the point of impact about 1” at
100 yards. It is very easy for a stock to move a barrel .005 to .010 of an inch.
Some rifles (a few) actually
shoot better with a pressure point(s) on the barrel. Too much pressure on the barrel can string the shots left, right,
or high depending on the pressure point.
Trigger Pull
To shoot well the shooter must have as light a trigger (weight the trigger
finger pulls) as he or she can handle.
The shooter must consider cold or wet weather, off hand snap shooting, etc.
when making this decision.
