Remington UMC 300 AAC Blackout Ammunition 220 Grain Open Tip Flat Base - L300AAC4A ammo review offers the following information; Designed from the ground-up to provide quiet, reliable performance, this round is perfect for AR-15s chambered in 300 AAC Blackout. The bullet was created specifically for the 300 AAC Blackout, combining the popular 220 grain, open tip design with a new, flat base. A cannelure ensures consistent loaded length and allows the brass crimp to hold the bullet firmly in place, eliminating the possibility of bullet setback. The powder load was developed to provide reliable extraction and cycling in the AR-15, while keeping the bullet subsonic. Primers are sealed to ensure ignition in all weather conditions.

The result is a round designed to load into any AR-15 magazine, feed reliably, shoot accurately, and do it quietly. Fantastic for use with a suppressor.

Comments and Reviews on Remington UMC 300 AAC Blackout Ammo 220 Grain Open Tip Flat Base - L300AAC4A
Solid .300 AAC BO ammo made by Remington UMC. Got to run unsuppressed with a carbine length gas tube with a standard buffer and reduced power spring. Prob run better suppressed or with adjustable gas block. Thankyou Target Sports USA.

Being a prime member love the free shipping and discount. The ammo I bought I needed for pig hunting and the price was not that bad. The only down fall to the site is not being able to buy 223 ammo and 22 ammo at a good price. Ken from Arkansas OH, and shipping is fast and quick.
