Lapua 223 Remington Match brass cases are coming back on the market in the USA after being scarce in 2023 and 2024. The packaging has changed to cardboard racks in 2025 (see photo), so I evaluated characteristics of 2025 brass (lot LPT05107) to those of 2022 brass (lot LPT02449) using virgin and once-fired brass.
There was less than a one percent (1%) lot-to-lot variation in case weight, case volume, neck-wall thickness, and muzzle velocity from standard charge between lots manufactured in 2025 and 2022. Low lot-to-lot variation of Lapua brass agrees well with studies that I did in 2023.
A data panel from the 2025 study which is an addendum to a larger 2023 Study follows. Methods are detailed HERE.


It is great to have high quality Lapua brass available again for match rifles that is interchangeable with brass I have previously used.
