Best Ammo for Home Defense: Handgun, Shotgun, and Rifle
January 20, 2026 · AmmoBin.com
Home-defense ammo has to balance effectiveness against over-penetration through walls. The right answer depends on your firearm. Here is a clear guide by platform.
Handgun
Use a quality jacketed hollow point, not FMJ — JHP expands and is less likely to over-penetrate. For 9mm, 124gr/147gr JHP is the standard recommendation. See our best 9mm self-defense ammo guide.
Shotgun (12 gauge)
Reduced-recoil 00 buckshot is the classic home-defense load — devastating at across-the-room distances and easier to control. Pattern your specific shotgun to confirm. Compare 12 gauge prices.
AR-15 / rifle
Counterintuitively, lightweight 5.56 rounds often fragment and can over-penetrate less than handgun rounds through interior walls. Choose a proven defensive load and verify reliability.
