Cowboy Action Tips
Use Winchester Super X Cowboy 45-70 405gr only in firearms chambered for 45-70 Government.
Check your match rules for velocity and bullet requirements.
Wash your hands after handling lead bullets and before eating.
Clean lead fouling from the bore regularly to keep accuracy consistent.
Winchester Super X Cowboy 45-70 405gr is a reliable choice for shooters who want a ready-made cowboy action ammo from a known maker.
Lever gun feeding
Flat-nose bullets are a safe choice in tube-magazine lever actions because the bullet tip does not rest on the primer of the round in front of it.
Older firearms
Have older or antique firearms checked by a gunsmith before shooting modern ammunition in them.
Steel targets
Follow match and range distance rules when shooting steel, and always wear eye protection.
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.
About Winchester
Winchester Super X Cowboy 45-70 405gr comes from Winchester, and the specifications listed here follow the maker’s and our distributor’s published data for this item. Compare loads by bullet weight, bullet type and intended use to find the best fit 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.
