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.

    These lightweight, 165 grain projectiles from Zero Bullets are great for crafting cartridges in both .40 Smith & Wesson and 10mm Auto. These bullets measure .400 inches in diameter and feature a full metal jacket (FMJ) as well as a truncated cone (TC) shape. FMJ-TC rounds are similar to semi-wadcutters and will make clean, recognizable holes in targets which makes competitive scoring or productive practice that much easier. 165 grains is light for both calibers and quite popular for a number of loads. Zero Bullets is company located in Alabama that is well known for great projectile quality at a low price.

    Save some cash when you create your own 10mm and .40 S&W rounds for practice and matches. These projectiles from Zero Bullets use proper copper jackets in a full metal jacket truncated cone (FMJ-TC) shape. Truncated cone style bullets are similar to a semi-wadcutter with a sloping ogive and flat nose which leaves nice clean holes in targets for clean scoring and group measurement. These bullets weigh 180 grains which is ideal for many recipes of both calibers. Zero Bullets is an Alabama manufacturer that has a great reputation for offering consistent projectiles at a low cost.

  3. Zero Bullets 40 S&W (.400" Diameter) 165 Grain JHP - 500 Projectiles

    $69.85

    In stock

    Cost Per Bullet 14.0¢ per bullet
    Bullet Weight 165 Grain
    Bullet Caliber 10mm, 40 S&W
    Quantity 500
    Bullet Type Jacketed Hollow-Point (JHP)
    Manufacturer Zero Bullet
    Manufacturer SKU 165

    Work up some high velocity .40 S&W and 10mm Auto cartridges with these premium .400 inch diameter projectiles from Zero Bullets. These bullets are jacketed hollow-points (JHPs) and are great for self-defense loads due to their expansion on impact which will open up a wider wound channel and have more efficient terminal effect on target. These bullets weigh in at 165 grains which is lightweight for both calibers and can be utilized for lower recoil practice loads with the proper data. Zero Bullets is an Alabama-based manufacturer that takes pride in their quality and offers great projectiles at low cost. Zero Bullets pre-segments the crown of their JHPs for more reliable expansion at a variety of distances and impact velocities.

    FedEx lost the shipment

    Thad in customer support was great. Called and reported lost shipment. A claim was filed with FedEx and Widener's promptly shipped again. I received order in three days and on a Sunday to boot! Great service! Ordered 1000 40 S&W caliber 165 grain JHP Zero Bullets. They look very uniform and well made. Loaded up 100 and test fired 5 shots with no problems. Load data: 5.2 grains Accurate #2 COL=1.125.

    Very Accurate, Good Appearance

    Very straight shooting bullets

    Review by Great Bullets (Posted on 11/7/2019)

    Chamber well and shoot accurately

    These chamber properly in a Glock 20 and seem pretty consistent, probably a lot more than I am. I shot 100 rounds out of this batch with no failures to feed. If the jackets were a little nicer looking I'd give them a five for quality, but they look kind of tarnished and blotchy. They shoot just fine, though. For plinkers they are totally acceptable.
