The IBC calculator supports 607 commercial rifle cartridges. 155 of them have measured accuracy figures from our published-manual validation corpus; the rest are fully usable, and their pages say so plainly instead of inventing a number. No cartridge page carries load data: pick a load from your manual, enter it in the calculator, and compare variants against the pressure ceiling.
Accuracy coverage computed from the published-manual validation corpus (9796 loads, 155 cartridges) with engine v1.1.14 (corpus build da7ac091). Page generated 2026-11-11.
