It looks like the approvals are still all over the place, with no reason to any of it. Multiple people are getting them approved in days, some in weeks, and some are still taking months.
My latest, filed as an individual via eForms:
#1 Certified June 19 - Approved July 18
#2 Certified Aug 6 - Approved Sept 10
So my average has been around 30 days, which according to ATF stats is slightly better than the current average of 41 days for a Form 4.

I had heard from numerous people that if your approval had reached 30 days, that if you call and inquire about the status, that it would be approved within 24-48 hours of the call. Ironically, my last one had gone over 30 days, so I called, and it was approved the next day!
I still don't understand why some people can get an approval in 48-72 hours, but it is still taking others over a month to get an approval. I especially say that because in my case, my second approval took over 30 days, even though I had just gotten an approval in the month before. Leave it to the worthless Fed Govt!
