Heavy Subsonic Performance for the 500 Auto Max Platform
Steinel’s 500 Auto Max 700gr Hard Cast “Omega” load was developed for shooters seeking an extremely heavy-for-caliber subsonic option for modern AR500 rifle platforms. Built around a massive 700 grain LFNGC hard cast projectile, this load delivers substantial momentum, reliable cycling characteristics, and powerful subsonic performance while remaining optimized for the operational realities of the 500 Auto Max platform.
Producing approximately 1,040 FPS from an 18-inch barrel, this cartridge offers the kind of deep-impact shooting experience enthusiasts expect from large-caliber modern sporting rifles while maintaining suppressor-friendly velocity characteristics.
Designed for AR500 & Modern Big-Bore Platforms
The 500 Auto Max platform continues to attract shooters who appreciate extreme heavy-bore rifle performance in a semi-automatic format. Steinel developed this load specifically for shooters who wanted a reliable heavy subsonic option capable of functioning properly within the dimensional and feeding limitations of the AR500 platform.
This ammunition is well suited for:
- AR500 rifles
- Big-bore AR platforms
- Suppressed shooting applications
- Recreational long-range steel shooting
- Heavy-impact target applications
- Shooters seeking maximum projectile mass
Case taper and platform geometry place practical limits on projectile length and overall cartridge configuration. This 700 grain Omega load was carefully engineered to maximize bullet weight while still maintaining reliable function and cycling behavior.
Built for Subsonic Shooting
The combination of substantial bullet mass and moderate velocity makes this load particularly attractive for shooters running suppressed rifle setups. The heavy projectile helps maintain strong downrange energy while avoiding the sharp supersonic crack associated with lighter high-velocity rifle loads.
This load delivers:
- Heavy-impact subsonic performance
- Smooth recoil impulse
- Strong suppressor compatibility
- Consistent cycling characteristics
- Reduced perceived blast compared to supersonic rifle loads
As with any heavy-for-caliber projectile intended for suppressor use, shooters should confirm projectile stability in their specific rifle configuration prior to suppressor use.
This 500 Auto Max load is for AR500 owners who want a heavy-hitting subsonic option. Case taper and physics make this the heaviest 50 cal bullet that will function well in your AR500.
