There had been 309 mass shootings in the US year-to-date as of 5 July 2022, about 12 per week.

Use the Gun Violence Archive's mass-shooting count for 2022 up to and including 5 July 2022, since this is the source the figure appears to come from. TRUE: the count is within ±3% of 309 (about 300–318), and the implied weekly average is roughly 11–13. MOSTLY TRUE: the count is within ±10% of 309. MOSTLY FALSE: the count is only matched by an unusual definition, or it differs from 309 by 10–25%. FALSE: the count differs from 309 by more than 25%. If a claim is judged against another tracker that uses a stricter definition (FBI, Mother Jones), that alone does not make it false, provided the GVA figure matches.
