Smith and Wesson and Winchester partnered to develop 40 Smith and Wesson ammo or the "40 cal" cartridge as a round for law enforcement. Their hope was to create a caliber that could mimic the performance of the FBI's reduced-velocity 10mm automatic round with rounds small enough in physical size to be carried with a medium-frame pistol.

40 S&W quickly caught on and remains a popular caliber for personal protection and range training today. Range shooters will likely opt for full metal jacket (FMJ) rounds with a non-expanding bullet while those seeking a round for protection will want to look at jacketed hollow point (JHP) ammo. In terms of ballistic performance, expect the lighter 40 cal rounds (155-grain) to leave the muzzle at about 1,205 feet per second and the heavier rounds (180-grain) to bring a muzzle velocity of about 1,050 feet per second.

Look for a wide selection of 40 S&W ammo for sale from trusted manufacturers like Federal, PMC and Hornady in the most common bullet types out there today, like full metal jacket (FMJ), jacketed hollow point (JHP) in the categories listed below:

    Hello, This is RickMax and I just tried out the 40 S&W 175 Grain SHP ammo and I was impressed. I was shooting my S&W SD40 VE which is a pretty reliable piece in my opinion at 25'. This ammo came out smooth and straight which is the highest praise I can give a bullet, I mean what more can it do. 40 rnds at my best target hitting speed and each rnd hit where I wanted with nary a foul. This 40 has a 14 rnd clip with one in the pipe so I was at max load firing 3 clips. So what's this mean to me? It tells me that since I carry fully loaded with one extra clip, in an emergency I am going to toss 28 rnds in the general direction of the problem with out worrying about a jam. If that does not dissuade the squirrel that is attacking me nothing will.
