Special Features

• The Dynapoint hollow point cavity is engineered to initiate reliable expansion on contact at the velocities the 22 WMR produces, delivering a wider wound channel than a round nose or flat point bullet of the same weight
• The copper plating applied to the full exterior of each bullet reduces lead fouling in the bore, keeping the barrel cleaner through extended range sessions and high-volume field use without the buildup that bare lead bullets leave behind
• Brass casing provides consistent dimensional uniformity from round to round, which directly supports reliable feeding and extraction across a wide range of bolt-action, semi-automatic, and lever-action 22 WMR platforms
• The boxer rimfire primer design delivers consistent ignition across a wide range of temperatures, making this load a dependable choice in cold-weather hunting conditions where primer sensitivity matters
• Winchester manufactures this load to the same quality standards applied across the full USA line, using domestic components and production controls that keep velocity and pressure within tight tolerances box to box

Practical Benefits

• The 45 grain bullet at 1,550 fps delivers a flat, predictable trajectory out to the moderate distances where 22 WMR performs best on squirrel, rabbit, prairie dog, and similar small game targets
• The copper plating keeps your bore cleaner between cleaning sessions, a practical benefit when you are running a high round count through a semi-automatic 22 Magnum rifle in the field or at the range
• The 50-round box format gives you enough rounds for a full hunting session or a complete range workout without buying more ammunition than you need for a single trip
• This load works across the full range of standard 22 WMR platforms including bolt-action rifles, semi-automatic carbines, and lever guns, making it a versatile choice for any shooter who owns multiple 22 Magnum firearms
• Whether you are stocking up for small game season, maintaining your 22 WMR rifle with regular range practice, or running suppressed varmint work where controlled expansion matters, your Winchester USA Dynapoint gives you a dependable, clean-shooting round built for the job

Winchester USA Dynapoint (USA22M) in 22 WMR is a practical choice for small game hunters and varmint shooters who need a consistent, clean-feeding copper plated hollow point load they can run through any 22 Magnum platform with confidence.
