I’ve got the Resonator in 9mm. Not sure if I’m using the correct terminology here, but the tube is slightly off center.

The kiosk makes the process easy. Takes about 20 minutes to do your finger prints & passport photo. If you buy from the local shop with a kiosk they shouldn't charge you a transfer fee.
I recommend a 30cal can, should cover most the calibers you have. The Resonator R2 is about $600, full auto rated & up to 300 win mag/300 RUM rated. Some cans have barrel length/caliber restrictions so make sure you look into that depending on the brand.
