Changes the law regarding the sale of firearm ammunition

HB 1956 requires most sellers of firearm ammunition in Missouri to obtain a license from the Secretary of State by December 31, 2026, for sales after that date, with exceptions for hunting clubs, non-profit organizations conducting events, target shooting facilities, and individuals selling limited quantities (up to 250 rounds annually). The Secretary of State will establish eligibility criteria (requiring sellers not to be prohibited by law from possessing firearms) and process applications starting September 1, 2026, with licenses valid for one year. Licensed sellers must also ensure employees handling ammunition are not prohibited from possessing firearms, and violations constitute a class D misdemeanor per sale. This bill directly affects most ammunition retailers and sellers, excluding specific hunting, recreational, and small-scale transactions.
