FREQUENTLY ASKED QUESTIONS
First, it's most likely not your firearms. Second, we only use premium quality projectiles that do not have inferior nylon binders which can cause many of the fore-mentioned malfunctions. Third, we have developed proprietary loading techniques and quality control that prevent all of the following common malfunctions with frangible ammunition:
• Broken projectile heads in chamber
• Multiple hits on target
• Short stroking ( Rifle)
• Projectile pushed in the case
• Failure to feed
• Failure to extract
• Erratic grouping
Our standard SDR line contains no heavy metals or heavy metal cores.
Aside from the shooter(s) being safe from ricochet, benefits of NPA frangible ammunition are the following:
- Ability to utilize training scenarios not permitted using standard ball ammunition
- Completely lead free environment
- Reduced range operation costs
- Reduced agency liability due to training accidents
- Reduced agency liability due to lead contamination
- Ability to reclaim copper powder
- Your agency is doing its part in the community to go "Green"
Yes. Our SDR line is designed to closely match the ballistics of duty ammunition.
We do not recommend it. Frangible ammunition was designed for training and offers no benefits over standard premium hollow point ammunition. Sintered Frangible ammunition behaves similarly to standard FMJ ammunition when it impacts soft tissue.
No. There are many myths floating around the internet stating that frangible ammunition is a magic material and will stop when it impacts light barriers such has drywall or plywood. Frangible projectiles are designed to break apart when it impacts a target harder that the projectile, use of AR400 steel or above is highly recommended.
The standard SDR line 45 grain .223 is designed to cycle all premium major manufacturers 14" M4 uppers and above (both impingement and piston system, in the STOCK MANUFACTURERS CONFIGURATION). A 55 grain .223 projectile is recommended for SBR's below 14".
Because frangible projectiles are less dense that standard FMJ ammunition they differ dimensionally which is effected by twist rates. For instance, a standard 45 grain .223 projectile is similar in size to a standard 55 grain FMJBT (M193) which is recommended for a 1 in 9 or faster twist rate. A 55 grain .223 is similar in size to a 62 grain projectile (M855) which is recommended for a 1 in 7 twist rate.
Please note: Frangible ammunition is not recommended for non-chrome lined barrels, if your agency has non-chromed line barrels please contact your NPA representative for a customized solution.
Out of service barrels worn or "shot-out" will show signs of "key-holing" sooner with frangible ammunition than with standard FMJ ammunition.
