DoubleTap offers a full range of 357 SIG loads, from light solid copper hollow points to bonded defensive bullets, so owners can pair this hardcast solid with a fast-expanding load for carry in town.
Buying ammunition by the box from the same production lot keeps velocity and point of impact consistent from one range trip to the next. Keep a record of the load you carry, check your ammunition for dents or loose bullets from time to time, and rotate your carry rounds so the ones in your firearm stay fresh. These simple habits help you get the full performance DoubleTap builds into every cartridge.
Before you trust any new load, fire enough rounds through your firearm to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Full-power loads produce more recoil and muzzle blast than typical range ammo, so practice with the DoubleTap 357 SIG 180gr Hardcast until you are comfortable with it, and store the rest in a cool, dry place in the original box.

Why Choose DoubleTap 357 SIG Ammo
Most 357 SIG loads use light, fast hollow points, but this 180 grain hardcast bullet takes the opposite approach. It keeps its full weight and shape, so it can drive straight and deep through tough targets. DoubleTap rates it at about 985 fps from a 3.5 inch barrel, 1025 fps and 420 foot-pounds from a 4 inch barrel, and 1050 fps from a 4.5 inch barrel.
When you compare 357 sig hardcast ammo, remember that heavy bullets change how a pistol runs. Fire several magazines of this 357 sig 180 grain hardcast load to confirm reliable feeding and ejection in your pistol, since some 357 SIG guns are tuned for lighter bullets.
