Manual

Use only standard Winchester
Magnum Rimfire (.22WMR)
ammunition loaded to U.S.
Industry specifications. Do not
fire .22 short, long, or long rifle
cartridges in this rifle or load
them into the magazine - they
are of smaller case diameter and
otherwise vary in size from the
larger .22WMR cartridge. They
can split or burst when fired in
the larger magnum chamber,
releasing hot powder gasses and
particle fragments out of the
action at high speed, possibly
resulting in injury to the shooter
or bystanders.

MAGNUM is chambered for, and designed
to properly function with, only the .22 Winchester Magnum Rimfire cartridge,
both jacketed and hollow point, manufactured to U.S. industry standards. Do not
use any other .22 caliber ammunition in this rifle as burst cases and the release
of hot powder gas can result. See “.22 Magnum Ammunition Warning”, below.
USE ONLY FACTORY AMMUNITION LOADED
TO U.S. INDUSTRY STANDARDS
However, your choice of ammunition may affect the functioning of this firearm.
Ammunition manufacturers use different powders, bullets and case specifica-
tions. If you find that you are experiencing feeding and extraction problems,
switching to another type or brand of .22WMR ammunition may improve the sit-
uation.
