Frequently Asked Questions
Is this Magtech 300 Blackout ammo suitable for suppressed rifles?
This 123 Grain FMJ load is a supersonic cartridge, meaning it will break the sound barrier and produce a supersonic crack even when fired through a suppressor. It is compatible with suppressed rifles and will function reliably, but if you're looking for the quietest possible report, you would want a subsonic 300 BLK load (typically 220 grain or heavier). That said, this load is an excellent choice for unsuppressed range use or when running a suppressor where hearing protection is still worn.
Will this ammo cycle reliably in AR-15 rifles chambered in 300 Blackout?
Yes. Magtech's 300 BLK 123 Grain FMJ is manufactured to SAAMI specifications and is designed to cycle reliably in standard AR-platform rifles chambered in 300 Blackout. The brass-cased, Boxer-primed construction feeds smoothly and extracts cleanly in both standard-length rifles and short-barreled rifles (SBRs). Always ensure your rifle's gas system is properly tuned for supersonic loads if you run both sub and supersonic ammunition.
Can I reload the brass casings from this Magtech ammunition?
Absolutely. Magtech uses reloadable brass casings with Boxer primers, making spent cases easy to resize, reprime, and reload. This is a significant advantage for high-volume shooters looking to reduce long-term costs. Simply inspect each case after firing for any signs of damage, and follow standard 300 Blackout reloading data from a reputable reloading manual for safe and accurate handloads.
