The NRA Freedom Match 703 and 707 are shot with an F-Class Rifle and competitors have the option of supporting the rifle with a rear and/or front rest or with a bipod and/or sling and rear rest. David Bailey took the win in the Open 703 Match after a shoot-off performance of 99-4x. A tie-breaking shoot-off was required in the T/R 707 match after Daniel Polabel and Nikolos Taylor both shot 97-2x scores. After the tie-breaker, Daniel Polabel became the winner of the NRA Freedom 707 Match.
This is the only mention of F class that I have see so far.
