I found this 22lr casing a few weeks ago at my local range... while I have seen a LOT of different 22lr casing in my lifetime I have never seen one like this!! It has a dimple on the base. Could this be a design to direct the burning of the powder ?? or??

Its a federal. Creating a more even powder burn is a safe guess.

Minor correction....

It's either Federal (very likely) OR it's the Russian target ammo that Federal got the idea from...

More than likely it's Federal Match ammo... supposedly it's to help the primer mix get settled in the rim properly during manufacturing, and/or aid in getting the "spark" from the primer to ignite the powder more evenly.. I've read both.

Yea it is a federal more than likely.

I wondered the first time I saw them. If they shoot there is a bunch of empty casings they must work

Its a Federal Gold Medal Ultra Match casing...

All the federal gold medal used to come like this till about a year ago. The $2/box Gold Medal Target was great stuff that compared in consistancy w Elly Club. No more though. They got bought out by Blount and they changed their cases and quality. No Dimple and less consistancy. I'm not sure if the high end GMmatch is still dimpled but I'm done with them anyway.
