A-Zoom 20 gauge shotgun snap caps (part no. 12313) give shotgunners a safe way to dry-fire, function-test, or safely store a shotgun without a live shell anywhere near the chamber. A-Zoom CNC-machines each dummy round from solid aluminum to precise 20-gauge chamber dimensions, then hard-anodizes it for smooth cycling and long service life. The design cushions the firing pin strike instead of letting it hit bare metal, protecting the pin over repeated dry-fire sessions on a break-action, pump, or semi-auto shotgun. Every ammunition order from Schaefer Defense ships fast, so a fresh set can be in the range bag in days, not weeks.

Key Specifications

• The gauge is 20 gauge, machined to the exact chamber dimensions of a live shell.
• Construction is solid CNC-machined aluminum, giving each snap cap the weight and feel of a real shell.
• Each round is inert, containing no powder or primer, so it cannot be fired.
• Primary use is dry-fire practice, letting shooters train trigger control without a live shell.
• It also works for function testing, confirming a new or reworked shotgun feeds and ejects properly.
• Shooters use it to safely store or decock a shotgun without any risk of a live shell in the chamber.
• Each pack contains 5 snap caps, enough for a double-barrel or a pump gun’s tube and chamber.
• Cost runs about $3.71 per snap cap, reasonable for a reusable training aid rather than a consumable.
• Shipping weight per pack runs 0.44 pounds, useful for shooters planning a bulk order.

Frequently Asked Questions

Can these be fired like real shells? No, A-Zoom snap caps are inert dummy rounds with no powder or primer — they cannot be fired and exist purely for dry-fire practice and function testing.

Can I leave these in my shotgun during storage? Yes, that is one of their main uses — keeping the firing pin cushioned rather than resting on an empty chamber between hunts or seasons.

Will a 12-gauge snap cap work in a 20-gauge shotgun? No, snap caps are machined to exact chamber dimensions for a specific gauge, so a 20-gauge shotgun needs 20-gauge snap caps like this set.
