40 s&w

10mm: A larger and faster round, with similar bullet weight (sometimes heavier if 200gr+ ammo) compared to .40. In average ccw sized guns (say 4" barrel or less), the ballistics can be strikingly similar compared to .40, but generally more penetration and expansion. Also, more RECOIL, and...

Thought this was the most understandable, fair and real world test I've seen and will surely start no controversy by settling that age old question once and for all time:

Hey guys, can anybody here help me out with what data Vihtavouri is giving for 40 S&W? Using N340 powder. My main thing is, I’m using RMR 180gr. FMJ’s. The closest thing I can find to that listed on Vihtavouri’s load data is “Fiocchi LTC“. Other than that, there is Speer HP, but not using...

Been wanting to add a hammer fired 40 S&W semi auto to my collection. I'm set on a Sig P239, but today at the LGS I saw a CZ-75 compact In 9mm. As you can guess, my first instinct was to ask if there's one/if they made one in 40 S&W. I instead just looked it up on my phone and yea there are .40...

We've had several threads recently that have shown, to my mind, inscrutable consistencies. One side always comes in with 'Handgun stopping power is a myth. and all handgun calibers are essentially within 20% effectiveness of each other. One poster asserted that the .357 Mag. is no more than...

Was shooting a little bit today using a target from Pistol Training. You start at 3 yds and back out to further ranges. This target is 5 yds. Not great but not real bad. I have seen others do much better. I shot my S&W SD 9VE with cheap Magtech 115gr bullets. The M&P 40 ammo was Freedom...

Hey all, I need to start out by saying up front I am a newbie at reloading. I am reloading the following brass, bullets etc... and something odd is happening and I am not sure what. Hopefully someone can square me away. Remington brass (.40 S&W) Berrys Preferred Plated Bullets 155gr Flat...

I am in search of Load data for a 40 S&W 175gr FP Lee Lead Cast Bullet using either HP-38 or TiteGroup powders. I have a Lyman 49th Reloading Manual. But it doesn't have either of those powders listed for a lead bullet of that weight. Pistol powders are very hard to find in my area...
