What Makes SinterFire GreenLine .300 AAC Blackout 110 Grain Frangible Brass Rifle Ammunition SF300BLK110GL-C 23% Off Stand Out?
The SinterFire GreenLine .300 AAC Blackout 110 Grain Frangible Brass Rifle Ammunition SF300BLK110GL-C 23% Off offers a unique solution for shooters seeking a lead-free, frangible option in the popular .300 Blackout caliber. This ammunition, manufactured by SinterFire, aims to minimize environmental impact and increase safety with its lead-free construction. It is a frangible round, meaning it’s designed to disintegrate upon impact with hard targets, reducing the risk of ricochet and backsplash.
My search for this ammunition stemmed from a growing concern about lead exposure at indoor ranges and the desire for a more environmentally friendly option. I was specifically looking for .300 Blackout rounds that could be safely used in steel target practice without the worry of dangerous ricochets, particularly when training in close quarters. The promise of a frangible, lead-free projectile was the deciding factor.
Unboxing the SinterFire GreenLine ammunition, I immediately noticed the clean brass casings and the consistent appearance of the projectiles. The rounds felt well-made and were packaged securely in boxes of 50. The weight was comparable to other 110-grain .300 Blackout loads I’ve used, giving me confidence that the ballistics would be relatively similar.
Compared to standard FMJ (Full Metal Jacket) .300 Blackout rounds from manufacturers like Remington or Winchester, the SinterFire offering stands out due to its frangible and lead-free nature. While FMJ rounds are generally cheaper and more readily available, they pose a greater risk of ricochet on steel targets. Subsonic lead-free options also exist, but I was specifically looking for a supersonic, frangible round for a specific training purpose.
My first impression was one of cautious optimism. I was excited about the potential for safer steel target practice and the reduced environmental impact, but I was also curious about how the frangible nature of the bullets would affect accuracy and overall performance. The 23% off sale was a great incentive to test these out.

First Use Experience
My initial testing of the SinterFire GreenLine ammunition took place at an indoor shooting range equipped with steel targets. The range had strict guidelines regarding ammunition types to minimize the risk of ricochet and damage to the facility. I ran the ammunition through my Daniel Defense MK18 SBR (Short Barreled Rifle) equipped with a red dot sight.
The ammunition performed remarkably well, producing minimal felt recoil and cycling reliably through my AR-15 platform. The noise level was consistent with other supersonic .300 Blackout loads. Upon impact with the steel targets, I observed the rounds disintegrating as advertised, with no visible signs of ricochet or backsplash.
I did not encounter any feeding or extraction issues during the first range session. However, I did notice a slightly stronger smell compared to traditional lead-core ammunition, which is likely due to the different composition of the projectile. It took a few rounds to adjust to the point of impact.
Extended Use & Reliability
After several months of using the SinterFire GreenLine ammunition, I can confidently say that it has held up well. I have fired approximately 500 rounds through my rifle, and it continues to perform reliably. There has been no noticeable increase in wear and tear on my firearm.
The ammunition remains consistent in its performance. Cleaning my rifle after each range session is relatively straightforward, with no unusual residue or fouling. It’s similar to what I experience with standard brass-cased ammunition.
Compared to my previous experiences with FMJ ammunition, the SinterFire GreenLine offers a significant advantage in terms of safety when shooting steel. It provides peace of mind knowing that the risk of ricochet is minimized. While the cost per round is slightly higher than FMJ, the added safety and environmental benefits make it a worthwhile investment for my training needs.
Breaking Down the Features of SinterFire GreenLine .300 AAC Blackout 110 Grain Frangible Brass Rifle Ammunition SF300BLK110GL-C 23% Off
Specifications
The SinterFire GreenLine .300 AAC Blackout 110 Grain Frangible Brass Rifle Ammunition boasts several key specifications. It is chambered in .300 AAC Blackout. Each round contains a 110-grain lead-free ball projectile.
The ammunition is packaged in boxes of 50 rounds. The cartridge case material is brass. The listed muzzle velocity is 2250 ft/s. The intended application is all-purpose.
- Lead-Free Construction: This is perhaps the most significant specification, making the ammunition environmentally friendly and safer for indoor range use.
- Frangible Projectile: This feature is crucial for minimizing ricochet hazards, making it ideal for steel target practice.
- Brass Casings: The use of brass casings ensures reliable feeding and extraction in most firearms.
These specifications matter because they directly impact the safety, performance, and environmental impact of the ammunition. The lead-free and frangible design reduces health risks and environmental contamination, while the brass casings and consistent bullet weight contribute to reliable cycling and accuracy.
Performance & Functionality
The SinterFire GreenLine ammunition performs admirably in its intended role. It is accurate enough for practical shooting and training exercises. The frangible nature of the projectile is its greatest strength, as it reliably disintegrates upon impact with hard surfaces.
The ammunition cycles reliably in my AR-15 platform, and I have experienced no malfunctions related to the ammunition itself. It consistently meets or exceeds my expectations for a frangible, lead-free .300 Blackout round.
However, one potential weakness is that frangible ammunition may not be ideal for hunting applications, as the projectile is designed to break apart upon impact. For hunting, a more traditional expanding bullet would likely be a better choice.
Design & Ergonomics
The design of the SinterFire GreenLine ammunition is straightforward and functional. The brass casings are clean and well-formed. The lead-free projectiles are consistent in shape and weight.
The ammunition is easy to load into magazines. There is no learning curve associated with using it, as it performs similarly to other .300 Blackout loads in terms of cycling and recoil.
Durability & Maintenance
The shelf life of the SinterFire GreenLine ammunition should be comparable to other brass-cased ammunition, provided it is stored in a cool, dry place. I have not experienced any issues with deterioration or degradation of the ammunition over time.
Maintaining my firearm after using this ammunition is no different than with other brass-cased loads. Regular cleaning and lubrication are sufficient to keep my rifle in good working order.
Accessories and Customization Options
The SinterFire GreenLine ammunition does not require any specific accessories or modifications to be used effectively. It is compatible with any firearm chambered in .300 AAC Blackout that is designed to handle supersonic ammunition.
However, as with any ammunition, it is essential to use appropriate optics and sighting systems to achieve optimal accuracy. The ammunition should also function well in suppressed platforms.
