40 Cal Bullets

Looking for bulk 40 cal bullets for reloading? Once you’ve got the right ones, the rest is easy!

The packages for sale on this page are only the bullets. If you'd like loaded rounds ready to shoot, please visit our 40 cal ammo page here.

40 S&W bullets for reloading usually weigh between 125 and 180 grains, although heavyweight 200 grain bullets are also available. A good 40 S&W bullet is also a good 10mm bullet, making .400 diameter bullets a versatile investment. The 40 S&W’s max pressure is lower at 35,000 psi, giving it a muzzle velocity anywhere between approximately 985 and 1,300 fps. Load data for jacketed bullets, lead bullets, copper bullets, and frangible bullets are all readily available for this popular handgun cartridge. With the right powder for your bullet weight and some small pistol primers at your disposal, reloading your own 40 S&W is just a matter of work. (We like to play Joe Don Baker movies in the background while we practice our science at the reloading bench.)

You’ll want to be careful about reusing brass while reloading 40 S&W. It’s a powerful cartridge, so cases that aren’t properly supported by a semi-auto during ignition often wind up bulging. A common resizing die won’t fix bulging completely, but a specialized one like the Redding GR-X is able to.

    Excellent service

    Ordering was easy. Delivery was fast and the product was as advertised. I will definitely order again.

    Not good in a Glock 20

    These bullets constantly fail to feed in a stock Glock 20 barrel. They feed OK in a KKM precision barrel, so-so in a Storm Lake barrel.

    Review by David (Posted on 9/12/2020)

    Bullets are great

    Bullets are great the only thing that upset me was when I was walking up the stairs at my apartment I kept finding random .40 cal bullets laying on the steps. After the trail of bullets I got my package and the box was spilling out bullets. I haven’t counted but hopefully I didn’t lose too many between shipping and and the arrival. Better packaging would be great

  5. Zero Bullets 40 S&W (.400" Diameter) Bullets 200 Grain FMJ-TC – 500 Projectiles


    In stock

    Cost Per Bullet 15.0¢ per bullet
    Bullet Weight 200 Grain
    Bullet Caliber 10mm, 40 S&W
    Quantity 500
    Bullet Type Full Metal Jacket Truncated Cone (FMJTC)
    Manufacturer Zero Bullet

    These bullets are great for making practice and match ammo for your 10mm Auto and .40 S&W pistols. These .400 inch diameter projectiles from Zero Bullets possess a full metal copper jacket (FMJ) and a truncated cone (TC) shape. FMJ-TC bullets are ideal for matches and practice because their overall shape allows for proper feeding while their flat noses leave easily discerned holes in paper and cardboard targets for easy scoring or group measurement. In addition, these rounds weigh in at 200 grains which is on the heavier side of either caliber and easily supported by widely available load data. Zero Bullets manufacture their products in Cullman, Alabama and are well-known to reloaders for their consistent quality.

    Outstanding bullet and price

    I ordered these bullets just a few days ago and received them on 6-24-16. I loaded some up at three different powder charges of AA9 using once fired brass. At 10 yards the lowest loading gave me an average velocity of 1165fps for an energy level of 603ft/lbs. Holy cow! That should take care of about anything in the lower 48 states. Accuracy was outstanding; out of 5 shots at 10 yds 4 made one jagged hole and the 5th was just 1/8" away.

    Very happy

    Functioned very good.

    Great bullets for 10mm

    I was about to send back a brand new Rock Ultra 10mm after shooting it with another brand of bullet and having absolutely no luck. In desperation I ordered these Armscor 180 grain and all is well. With these bullets and the same loading as before my new gun became a tack driver. Awesome quality bullets that I will definitely be ordering again.

    Review by James (Posted on 7/5/2021)


    Well, due to the industry's inability to manufacture primers and offer them to the public, I haven't been able to reload these .40 cal bullets. However, they appear to be well manufactured and cost friendly...and Widener's service was exceptional.

    Review by Mick (Posted on 6/29/2021)

    Armscor bullets

    As we know, reloading components have been hard to get. I've never bought Armscor bullets before, but I was very happy with the quality of these bullets for my 10mm.

    Review by Marty (Posted on 6/22/2021)

    Overall, very good.

    I am not as experienced as many others when it comes to reloading, but these came in handy during this ammunition shortage. My son is a new police officer, and the PD is having difficulties getting the practice ammunition they ordered. The PD uses 165gr bullets, but 165gr bullets for reload are few and far between too. The 180gr, with a little bit of reading and math work, can be loaded to provide decent ammunition for practice, if nothing else it keeps them familiar with their issued firearm.

    Review by Sawdust (Posted on 6/21/2021)

    Good bullet ****

    Great target bullet @ 10yds very accurate as distance increases they seem to vary in target strike at 25yards 3.5" circle can be achieved Working on new loads will follow up.

    Review by Vince (Posted on 11/11/2020)

    Good product -- good service

    Though I have not yet had a chance to load and shoot these (I'm trying to conserve both primers and powder) my inspection of the product shows them to be of good quality. I would certainly recommend these to other shooters. I likewise tip my hat to the good service offered by Wideners during these troubled COVID times.

    Review by Donald (Posted on 11/11/2020)
