Behind the scenes

 * Joshua Sawyer stated that the .22LR variant of the Varmint Rifle "did such pathetic damage that no one wanted to use it," resulting in it instead being chambered for the more popular 5.56mm/.223 ammunition, out of "convenience."
 * Joshua Sawyer also states that "in rimfire ammunition, the rim of the case itself acts as the primer, but is destroyed in the process. This makes reloading rimfire cases difficult and usually not worth the effort."  For that reason, .22LR ammo in Fallout: New Vegas did not yield .22LR cases.
