IMPORTANT: This owner’s manual pertains to the
Model 70 manufactured from 1992 to present. If you
have an earlier model, please contact our Customer
Service Department for an earlier owner’s manual at
(800) 954-6427. Your Model 70 may have a controlled
round feed bolt, a controlled round push feed bolt or a
push feed bolt. Operation, removal and disassembly of
the bolt as discussed in this owner’s manual are the same

g eneral D eScription
The Winchester Model 70 bolt-action rifle is truly the
“Rifleman’s Rifle.” Its natural balance, handling,
pointability and proven reliability have made it a
favorite the world over.
The Model 70 features the highly popular, Pre-’64 type
bolt with claw extractor and Controlled Round Feed,
proven under actual hunting and shooting conditions.
g eneral o peration
The Model 70 is a bolt-action rifle that operates by lifting
the bolt handle, drawing the bolt rearward and then
sliding the bolt forward and rotating the bolt handle
downward until it stops. This process takes a cartridge
from the magazine and loads it into the chamber for firing.
The Controlled Round Feed bolt design is a big part of
the Model 70 legacy. Its massive claw extractor (Figure 1)
secures approximately ¼ of the cartridge base and fully
controls the cartridge as it enters the chamber. This design
also allows the cartridge to be extracted even if it is not
fully chambered.
The Model 70 features a precision-machined coned
breech that aligns the cartridge with the chamber without
damaging the bullet point. This improves accuracy and
ensures smooth, snag-free feeding as the cartridge neck
and shoulder are guided into position (Figure 2).
A manual ejector gives more control over cartridge
ejection. The Model 70’s Pre-’64 type design uses a blade
system that allows you to vary the amount of ejection
force. Pull sharply rearward and the cartridge ejects clear
of the rifle. Pull slowly and easily remove the cartridge
from the action (Figure 3, page 8).
A push feed design with a recessed bolt face and plunger
style ejector merely pushes the cartridge forward until it is
seated in the chamber. It then snaps over the rim of the
cartridge, ready for extraction.
Operation of left-hand models is identical, except that the
bolt handle and ejection port are located on the left side
of the receiver.
All operations of the Model 70 are illustrated in this
owner’s manual with a right-hand model.
