Very unofficial .40 S&W FMJ ammo test
My $0.02 cents....I performed some VERY unofficial .40 S&W ammo tests on Sunday. FMJ rounds from Fiocchi, Magtech, Winnchester, Federal(reddish maroon and silver box). Bench rest group testing from approximately 140 feet with my Cx4 Storm, a red dot and a bench rest. 14 rounds shot from each brand.
Most accurate: Fiocchi was good followed closely by Magtech. The cheap Walmart Winnchester and Federal FMJ basically performed the same and the grouping was pretty poor.
Best penetration: One round from each manufacturer shot from 70 feet, Fiocchi penetrated 2 and 3/4 2x8 boards, followed by the Federal (2 and a 1/2), followed by Magtech (2 and a 1/4) and Winnchester (2 and a dent).
One other note: The Fiocchi and Federal bullets were fully encapsulated in brass, so less exposure to lead dust when shooting these. The other two had exposed lead on the back of the bullet.
My Conclusion: For cheap plinking, the $13 Federal ammo seems like a good choice, but I've noticed some strange things with it. My Taurus 24/7 pistol experienced several jams the last time I used this stuff, and my Cx4 also had some strangly weak brass ejections. I think I'm going to purchase more Fiocchi ammo.
Just thought you guys might be interested. :)
