Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Ordnance fell 0.5% over the last 12 months, but all of its main inputs rose faster: copper and brass mill shapes +30.0%, steel mill products +27.6%. That cost pressure may still pass through to prices.

A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Small Arms, Ordnance, and Ordnance Accessories Manufacturing (BLS series PCU33299T33299T), published by BLS. Base Period: the index value published for September 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
The only real government index for defence small-arms contracts. No narrower "small arms only" or "ammunition only" series exists alongside it.
Split defense contracts into aircraft, naval, land systems, missiles, and small arms. Aircraft (PCU336411336411), naval systems (PCU336611336611), and small arms/ordnance manufacturing (PCU33299T33299T) have real, published US government price indices. Land systems and missiles do not, confirmed by direct check against the BLS API. Build those two from a weighted input composite instead.
Escalake tracks US PPI — Small Arms, Ordnance, and Ordnance Accessories Manufacturing, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
