Description
Winchester USA Ready 40 SW 170gr ammunition from Winchester (USA Ready) loads a 170 grain Hex Vent Hollow Point in 40 S&W. Each box holds 20 rounds.
Built for Personal Defense
This load pairs a 170 grain Hex Vent Hollow Point with the 40 S&W, a combination designed for personal and home defense where controlled expansion and reliable feeding are the priorities.
A defensive hollow point is designed to expand on impact, which helps it transfer energy to the target and reduces the chance of over-penetration compared with full metal jacket practice ammunition.
Before you trust any defensive load, run enough of it through your own handgun to confirm it feeds, fires and ejects reliably from every magazine you plan to carry. Once Winchester USA Ready 40 SW 170gr proves itself in your gun, stay with it.

Carry and Defense Tips
Use Winchester USA Ready 40 SW 170gr only in firearms chambered for 40 S&W.
Test your carry load in your own firearm before relying on it.
Rotate your carry ammunition periodically and avoid chambering the same round over and over, which can set the bullet back.
Learn and follow the self-defense and carry laws in your state.
Winchester USA Ready 40 SW 170gr is a reliable choice for shooters who want a ready-made personal defense ammo from a known maker.
Practice and carry ammo
Many shooters practice with a matching-weight full metal jacket load and save the defensive ammunition for carry. Shoot a box of the carry load now and then to confirm the point of impact still matches.
Training matters most
Ammunition is only one part of personal defense. Regular practice, safe storage and professional training matter more than any single load.
Home storage
Store defensive ammunition in a cool, dry place and keep it secured from children and unauthorized users.
Reading the box
The box lists the caliber, bullet weight and bullet type. Always match the cartridge to the caliber stamped on your firearm’s barrel or slide, and never fire ammunition that is not specified for your firearm.

Buying the right amount
When you find a load that performs well, buy enough for practice and the full season at once. Ammunition from the same lot tends to perform the same, which keeps your results consistent.
Safety first
Always treat every firearm as loaded, keep the muzzle pointed in a safe direction and keep your finger off the trigger until you are ready to shoot. Wear eye and ear protection every time you shoot.
Understanding bullet weight
Heavier bullets in a given caliber usually leave the muzzle slower but carry momentum well and resist wind drift, while lighter bullets shoot faster and flatter at shorter ranges. Neither is better in every case; the right choice depends on the game, the distance and your firearm.
Choosing the right load
Start with the job you need the ammunition to do, whether that is hunting, target shooting or practice. Then match the load to that job, and finally test a few boxes in your own firearm, because every barrel has its preferences.
