If you mean the REMINGTON 660 (gad, I am getting good at mind reading!) it is a very nice BOLT action rifle. See link below.
The Garand rifle is a semiauto, not a bolt action. Do you have a Model 1903A3 bolt action? A Model 1917 bolt action?
Rifle or shotgun? What type of action; bolt, pump, semiauto, lever? What caliber or gauge?
Who made it? Bolt or semiauto? What do you want to know?
value of your Remington nylon 11 is from $500-700, there is one for sale on guns America now listed for $660.
For many, open the bolt. Check that it is unloaded. Depress and hold trigger, and slide bolt out of gun. However, other have a different technique. Mauser rifles have a blt release on the right side of the frame. A Remington 660 has a small tab you depress with a screwdriver, etc. We could give you a better answer if we had the make and model of rifle.
easy to answer the 700raptor. if tuned right can get to 90mph with simple bolt ons. 700raptor is way faster than that timpsy 660
