How Many C4 for a Stone Wall in Rust?

Calculated — Computed from a versioned dataset — reproducible in the tool below.

C4 is the cleanest answer but rarely the cheapest one. What actually decides a raid is sulfur, because every explosive in Rust is ultimately a sulfur cost, and sulfur is the resource you spend hours farming.

Two C4 costs 4,400 sulfur in raw materials. Four rockets cost 5,600. Ten satchel charges cost 4,800. So on pure sulfur, C4 is the most efficient way through a stone wall — but it needs a tier-three workbench, which is a serious investment for a small group early in a wipe.

Satchel charges are the early-wipe answer. They only need a tier-one workbench, they are cheap to craft, and ten of them will open a stone wall. The trade-off is noise and time: satchels have a fuse, they can dud and need re-throwing, and standing at a wall throwing ten of them makes you a target for a long time.

Explosive ammo deserves a mention because the raw sulfur number looks bad — 185 rounds is 4,625 sulfur — but it comes with a rifle attached. You are not committing to a raid before you know what is inside; you can open a wall and keep the gun. For small groups who might get counter-raided, that flexibility is often worth the extra cost.

A word on which wall to hit. These numbers are for a stone wall taken from the hard side. Almost every base has a cheaper way in: a door is usually softer than the wall next to it, and a garage door or sheet metal door may cost you a fraction of the wall. Before you commit two C4 to stone, walk the base and check what else is exposed. Raiding the wrong surface is the most expensive mistake in Rust.

These figures assume a fully upgraded stone wall at full health with no external repair during the raid. If a defender repairs mid-raid your requirement goes up.
