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.

    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.

    Hope to order from you again soon, wish every place I order from was you guys.

    The reason I give you a maximum rating is because of your service, since all I ordered this time was bullets this is an item that is hard to rate, these worked great, but what most impressed me was you speed of service.
