Generally we are hearing that it is taking 3-5 months from the time you submit your ATF forms for approval. A local gun store Shooters of Jacksonville told me they have two agents assigned because of the number of transfers they do. They stated that this means that ATF Form 4 applications that they sent in are processed faster than at other locations. While I do not know if this is true, I can state, that a recent Form 4 I submitted through Shooters only took 75 days from the date I signed it, until receiving the approved Form 4.
If you want to check on the status of your Form 4 or Form 1, you will need your serial number and to contact ATF.
