10mm Bullets for Reloading

This page features our 10mm bullets that are used to reload. If you are looking for loaded rounds that are ready to shoot, please head to our 10mm ammo page.

The 10mm is kind of the “redo” of pistol cartridges. Its handgun and recoil were both deemed too heavy by many law enforcement officers, so the 40 S&W was created to take the 10mm’s place. But you personally don’t mind a little more recoil when it goes along with the 10mm’s immense power.

Many people have noted that quality matters even more than usual when it comes to the 10mm. That plus its high price tag encourages a lot of shooters to reload the massive round. The 10mm’s parent case is obscure by now – production of the 30 Remington pretty much ceased by the late 1980s. Fortunately new 10mm brass is popular enough, as are the large pistol primers and conventional powders you need to reload it.

10mm bullets for reloading are typically jacketed and range in weight from 135 to 200 grains. JHPs and XTPs will make fine self-defense loads, and you can even make your own hunting cartridges. Several states allow hunters to take whitetail with 10mm. Just be certain to follow the 37,500 psi pressure limit and you can do whatever you like with your .400 diameter bullets.

    Great price, good quality

    Have used Berrys for 9mm -Luger, 9mm Makarov , 40-S&W and 45ACP, never a problem with quality or value.

    Excellent service

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

    Review by Jordan (Posted on 10/8/2020)

    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

    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.

    Great so far

    I've loaded about 150 of them so far and they are very consistent and shoot great! 10/10 would buy more

    Review by Joe (Posted on 1/22/2022)

    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.
