Your Questions Answered
Is this suitable for a compact revolver like an NAA Mini?
Yes. This ammunition is engineered to perform in short-barreled firearms. The FTX bullet is designed to expand reliably at the velocities achieved from barrels as short as 2 inches, making it a solid choice for small-frame defensive revolvers.
Why do you sell more of these on weekends?
Our staff notes these are frequent range day purchases. Customers who carry 22 WMR for defense use the weekend to function-test and practice with the exact ammunition they rely on. It’s a practical step in maintaining proficiency.
How does the FTX tip prevent clogging?
The polymer tip is housed inside the jacket‘s opening. Upon impact, it is driven rearward into the lead core, forcing the jacket to peel back into petals. Because the tip is internal at impact, it cannot be plugged by material like denim or heavy cloth, ensuring expansion.
