Plain 5.56 with the powder doubled and the bench raised to Level 3. Same metal, same yield; you pay in sulfur and a slot in the Level 3 research queue.
Your group has one player who lives on the roof with a bolt action rifle. That player is the reason to learn this blueprint, and nobody else needs it. Next to plain 5.56 the craft keeps the metal and the yield and doubles the powder, so a full stack comes to 860 sulfur against 440.
The harder cost is the bench. HV waits for a Level 3 workbench, where the scrap list is long: any group that raids learns explosives there first, and HV can wait until they are done.
The craft itself is tidy. Each one uses exactly one batch of gun powder, so no powder is ever left over, unlike plain 5.56. Craft a few mags for the sniper and keep the AK on plain rounds: at compound range the extra powder buys nothing.
