10mm  Ammo by Sellier & Bellot: Your Bren Ten or Colt Delta Elite will run flawlessly with this ammunition from Sellier & Bellot. These Czech-made 10mm Auto rounds are manufactured using top-grade components.

These include reloadable brass casings that are checked for proper wall thickness and non-corrosive Boxer primers that are free of mercury.

These cartridges fire a full metal jacket (FMJ) bullet that weighs in at 180 grains and offers shooters a balance between felt recoil, flat trajectory, and practical training impulse.

A sloped ogive grants the bullet seamless feeding while a flat nose helps create clear, circular holes in paper or cardboard targets. This effect allows shooters to measure their groups with precision for more effective practice. Sellier & Bellot has a rich history of component and cartridge production which reaches all the way back to 1825.
