Frequently Asked Questions

How does the M963 armor-piercing round perform against steel plates?

The Portuguese M963 AP round, featuring a 145-grain hardened steel penetrator, demonstrates significant armor-piercing capability. It successfully penetrated 3/4" mild steel and 1/2" AR550 steel, and created cleaner holes than other rounds on 3/8" AR500 steel.

What is the difference between the M963 and P80 rounds?

The M963 has a longer steel penetrator core and generally maintains higher velocities, allowing it to penetrate thicker and harder steel plates more effectively than the Israeli P80 round, which has a shorter penetrator and can suffer from inconsistent performance.

Can the M963 round penetrate AR550 steel?

Yes, in testing, the M963 round, fired at 2713 FPS, successfully penetrated 1/2 inch AR550 steel. Its penetrator tip pushed through the back of the plate without deforming, showcasing its effectiveness against hardened armor.

What rifle setup was used for the M963 and P80 testing?

The testing utilized an MDT CRBN stock, a Solus 700 pattern action, and a CMMG Zeroed 46 suppressor. This setup was used to accurately measure the performance of the 7.62x51mm NATO rounds against various steel targets.
