DoubleTap Ammunition’s .357 SIG 180-grain Hardcast Solid load (brand part no. 357S180HC) trades expansion for straight-line penetration, built for shooters who need a bullet that holds together no matter what it hits. The wide-flat-nose, gas-checked (WFNGC) hardcast projectile is cast from a harder lead alloy than typical jacketed bullets, so it keeps its original diameter and shape driving through bone and heavy muscle instead of flattening out early. DoubleTap markets this as a true woods load for .357 SIG, rated with enough penetration to handle deer, hogs, and black bear when a standard defensive hollow point would fall short. Each box ships 20 rounds from DoubleTap’s Utah facility. Ranchers, backcountry hikers, and anyone who carries a .357 SIG where four-legged threats outnumber two-legged ones will find this loading fills a gap most factory ammunition in the caliber does not address.

Key Specifications

• The chambering is .357 SIG, a bottlenecked round built for duty and carry pistols that demand high velocity in a compact platform.
• The bullet weighs 180 grains, adding mass and momentum behind the flat meplat for deeper penetration.
• The profile is a wide-flat-nose gas-check (WFNGC) design, crushing a wide, straight wound channel instead of tapering to a point.
• Construction is hard cast lead alloy, harder than standard jacketed bullets so the projectile holds its diameter and shape through bone and heavy muscle.
• A gas-check base protects the bore from lead fouling and helps the bullet hold velocity and stability at .357 SIG pressures.
• The load is rated for deer, hogs, and black bear, positioning it as a true woods and property-defense round.
• Cost runs about $1.14 per round, reflecting the hand-inspected, small-batch nature of DoubleTap’s hardcast line.
• Each box holds 20 rounds, a standard range-and-carry quantity.
• Case lots total 1,000 rounds, convenient for ranchers and property owners who keep this loading on hand year-round.
